: The transmission IS rubbish...Top Gear was right!

Actually, it is the shifter that is rubbish!

So I am ripping along at the top of 4th and go for a nice gentle shift to 5th(keep in mind that this is around 110mph+ and the shifter goes over into the reverse gate and GRIND. Pull it back to nuetral and go for 5th again with the same results, give up and shift to 6th. Go straight foraward into 5th with no problem, downshift into 4th and go back up to 5th with no trouble on the round. Furthermore, reverse is very difficult to engage and usually results in the selection of 5th instead.Go figure, you can't get reverse from Nuetral but you can get it just fine from 4th at 110MPH! :cookoo:

I can't wait for the Lasstss bushings and UUC shifter combo and have high hopes that it will make the gear box enjoyable!

BTW, THis is no case of driver error as I know the car and am an experienced rode racer and have driven plenty of difficult gearboxes. This one has just lost a clear delineation between the 5th and reverse gate. Had it into my dealer which is very good and they inspected the entire linkage proclaiming into normal and crappy. They suggested....you guessed it, I UUC shifter! :histeric:

Sorry, just need to vent about one of the worst shifter mechanisms that I have driven in any street or race car in the last 15 years. I would venture to say that this is worse than my prepped E36 M3 that would line up the 3rd gear gate with first coming out of a sweeping high-speed corner. At least there you could predict it! :D

That aside, had an enjoyable time with the V yesterday and found an '04 CLK55 AMG that was willing to play from 70-110 on several runs. The poor guy never had a chance which made me feel bad as that is truely a wonderful car. Too bad they took the best AMG car and stuck the worst motor in it, all because of marketing! If it had the blown V8, the results would have been very different.

Anyway, just thought I would rant and praise the V in the same post! :yup:

I had the exact same thing happen to me (not sure about what speed I was at, though).

What struck me as odd about it is the "CTS-V Details Book" states that the V has a reverse lockout mechanism to prevent this from occuring. The document is posted on the FAQ here:
http://www.cadillacfaq.com/faq/answers/pdf/vsales.pdf
This is listed as a sales feature, right after the "skip shift feature", LOL.

Specifically, it states, "a reverse lockout system consisting of a reverse lockout solenoid that operates the reverse lockout mechanism is used on the T56 transmission to prevent the driver from shifting into reverse when the CTS-V is moving forward at speed of 3 mph or greater".

At the time I rationalized that I just imagined I missed 5th for reverse, and ground 5th with the clutch not fully depressed, or something.

Maybe I should have a dealer look at it just so they can reassure me "there's nothing wrong with the car".

If you use a lot of force the solenoid won't completely stop reverse from grinding.
When the '06 V gets the LS2 will it get the shifter improvements that the C6 got?

I will agree that the shifter is very rubbery. I don't have 15 years race experience, but three VR6 Vws. When my car was in the shop I went into the dealer and there was a '05 vette on the floor so I hopped in. The shifter in that was so crisp! Why don't we have that?:banghead:

What good does this response serve? The complaint is not about manual transmissions, in general. Its about this transmission in this application. Don't even try to pretend its not rubbery in feel, long in throw, and poor in feel. What good is reverse lockout if it doesn't lockout enough to prevent grinding.

I've almost exclusively driven manual cars, and I've had manual pickups with better "feel" than this. How many guys on this list have changed their shifters out to try to improve the feel. Its a bigger problem for the V than the differential, as its something that scares off buyers before they even own the car (both through bad mag reviews and on their own test drives).

This is a legitimate complaint, so don't wave the GM rah, rah flag on the "quality feel of the 6 speed", and tell people who bought the car to go elsewhere. If enough do, there may not be any more V. This is one of those complaints that Cadillac can and should remedy. Its not to be excused. Hell, they made this car a 6-speed to attract serious enthusiasts. Now your telling those enthusiasts to go buy an automatic (SRT or AMG perhaps). That's just stupid. Expecting every buyer to fix their own shifter to have the car be what it should have been is really dumb -- even more so than cheaping out on the differential.

daytripper,

No one is saying the shifter feels great and at times I've hated it. It was a mistake to put this transmission in a car like the CTS-V because a lot of potential customers will be turned off by the poor feel. This is a transmission that's more at home in a Viper, Camaro, Trans AM or Corvette, than it is in a Cadillac sport sedan.

Although, the 6 speed manual in the V is something I'll miss if I decide to get the STS-V. I don't mind the transmission now that I've driven the car for nearly 2 years but it's still sub par compared to its competitors.

I'll be amazed if the next CTS-V (if they make it) dosen't have a 6 speed auto. GM doesn't seem to show much interest in manual transmissions, probably because that bulk of American drivers don't know how to shift. I'd actually like to see the V taken up a couple of notches, and priced around $60,000. Offer a dual clutch transmission as an option, a SC small block or the LS7, and a solid rear end / cradle.

10-24-05, 01:04 PM
Damn it...thats what ive been saying for the past year! Running through the gears SUCKS and to make it worse...the dealer can only say...it shifts fine! What short shifter are you guys using and does it help any in shifting gears? It makes the throw shorter, without a doubt, but as to actually getting it in first gear...does it make a difference?

10-24-05, 01:24 PM
Shifting from 4th to 5th should be second nature. I find I have to make sure I don't grind reverse going into 5th. I asked a while back if we had a lockout after hearing that grinding. Please fix it.

LMAO--the timing of your post is actually quite scary, as I was just going to do a search on this forum on the EXACT same issue; I mean EXACTLY...

I have a UUC shifter and the problem does NOT go away AT ALL; not one iota.

I just got back from the dealer, but their transmission specialist didn't have time today to look at it. I scheduled an appointment for next Tuesday for him to look at it, but, reading what you have said, it might just be for nothing.

I have found that the "lock-out" to reverse is actually quite feeble. While I consider myself a fairly powerful man, I can assure you that I'm NOT shoving the crap out of it to get past the "lock-out;" it's just not that strong/resistant. In other words, next time you are driving, say 60mph or something, just push to the passenger side of the car, like you were going to shift into reverse. By all means, don't push it up into reverse, as that will result in a nasty grind, but you can test/see just how strong the solenoid is (which it isn't...)


Specifically, it states, "a reverse lockout system consisting of a reverse lockout solenoid that operates the reverse lockout mechanism is used on the T56 transmission to prevent the driver from shifting into reverse when the CTS-V is moving forward at speed of 3 mph or greater".

Is there anything out there that is a simple solution to this problem? Perhaps a solenoid that generates more than like 1 lb of counter-pressure might help...

It's so frustrating.

#1 concern about this car: REAR DIFFERENTIAL
#2 concern about this car: the CRAP SHIFTING TRANSMISSION!

ARGH!

It's ironic that my '97 Z28 Camaro shifts 1,000 times better than my Cadillac in my mind...

10-24-05, 03:48 PM
Try palming the shifter from 4th to 5th. it will naturally want to go into the propper gate, and you will NEVER grind reverse if you do it in this manner. Its faster too. Same technique applies from 2nd to 3rd. You'd be amazed at how much more accurate, and quicker this technique is.

UUC didn't help here either, nor did Exedy clutch/fly. What did help was shifting like shooting a rifle--relax, breathe out, follow through. I agree-- a simple palm of the shifter or a flick of the wrist and it usually finds fifth pretty easily, in my car at least. I've driven manual transmissions for 25 years, and this one has taken me the longest to master...that said, I think the tranny will outlast just about everything in this car.

keeks,

The linkage is the issue. When (if) you have swapped out the shifter, then you know about the spindly long attachments to the tranny. These are the slop causers. The issue is that this is not a directly connected shifter.

I was about to post that the linkage was likely the issue, but you beat me to it. Doesn't the Mallet shifter replace the linkage too (maybe some other aftermarket one). Like I said before, the owner can only be expected to correct so many of the wrongs -- Cadillac has to meet us somewhere in the middle.

I agree with those who point out that when you shift carefully, guiding the shifter to its gate, it goes where you want it. Its when your quickly running through the gears, or slapping/forcing/hurrying the shifter into gear, its tough. I guess that's more of the kind of no-no driving Cadillac did not expect. Note to group. No racing through the gears, take it nice and easy and slow guys...
After all, this isn't a Porsche or a Miata, or some other car with a shifter that receives praise.

Don’t mean to put more gas on this fire, but I have to ask, is this another case of mechanical differences in the actual linkages or transmissions between some of the V’s. I have been driving standard for about 40 years ( ya… I am an old guy). I have a UCC shifter on order through the group buy so I clearly think that the shifter could be cleaned up and shortened up, but I have never experienced the issues that are being described here. I have done may share of “spirited” driving and aggressive shifting with the V. I have banged a gate or two, but never got past the reverse gate and never any issue going into first.

Yeah, and then everytime you try to start in 1st you put it in reverse accidentally...Think about the nightmare accidents that would cause in rush hour traffic.

10-24-05, 05:54 PM
How often do you quick shift into first though? ;)

Typically there requires more force to pull a transmission into reverse. When powershifting through the gears it would be easier to hit reverse with GM's layout and nigh impossible to do it in the one I presented.

In fact, it is quite a pull over to the left to select reverse in the cars I have driven with that layout.

10-24-05, 06:12 PM

Like the ZF in the C4. Never accidentally hit it going into 6th because it is a straight back shift and you are NEVER shifting into 6th fast anyway.

Much better place for R. Never understood why the T56 had it up near 5th....

I had the two other shift patterns in other cars mentioned and the both work way better than what we have laid out. I've changed the way I shift now. If I palm the shifter on top or grab it I have a much greater chance of hitting reverse. Oh well, I still love this car.

JOEYCTS-V
10-24-05, 06:32 PM
I never had a problem with hitting reverse instead of 5th until it happened last week. I was so shocked when I heard a grinding noise. I also noticed my UUC shifter just doesn't feel like it did when I first installed it. I'm going to take a peak under there and see if something got loose or damaged. Is there anything I should look for inparticular?

I've complained to no avail the difficulty getting it into 1st (from a stop) at times in my V. I've had friends who take it for a spin straight up ask me WTF is with your CAGS in 1st - I'm like there is no CAGS!!!. 1st is impossible for me to get into every maybe 1 in 20 shifts - not near impossible, absolutely impossible - I've tried to put force on it (and double triple clutch) no dice until I roll a slight bit then it goes in but you can feel it notch halfway as it has since day one.

I'm not a fan of the t-56 at this point, and yes I've driven it in a Viper, Vette, WS6, etc.

i am not going to go ahead and say that this shifter is really that great but at the same time while I have defintely had some grindingly bad experiences they have all been due to user error. Now that I have put about 10K miles and gone through the gears a zillion times I have to say that I very very RARELY ever experience any misshifts anymore. Reverse is kind of a pain in the ass and can be a pain to get it in there. I have found that by:

1.) disengage parking break and roll a smidge
2.) hold clutch put in first gear
3.) NOW put it into reverse (especially while rolling a little helps)

I have had some 4th to 5th woes but nothing compared to 1st to 2nd. You have to be really smooth bringing down 2nd gear because if you get off the track you will find that you have to put it back in neutral and really kind of bring it left and up a little before bringing it back down into 2nd.

My biggest GRINDS have been just plain me missing 3rd gear (shivers) by being inexperienced and a little overanxious... haven't done this in a LONG time

I have the B&M shifter and it is about the same, better than stock but the transmission itself feels clunky and the noise transferred seems like the trans has issues. Probably the remote shift rod that kills the shifting feel. My Z06 shifted much better stock and it couldn't be more of a remote shifter, guess it was much better designed. BTW, B&M has tips on shifting in this catalog that follow what most are saying here (ie easy does it)...

I've had the same problem at the track at over 100+, 4th red going to 5th. I think they must figure your not suppose to go over 99 (3 digits) so the solenoid must think it's OK. I'm more aware now so I know it's coming over 100.

Anybody got a lonely stretch of highway to test? Not to grind but to see if the shift gate is open > 99 mph. Hello, onstar.....:crowded:

In all honesty, this is, by far, the best setup.

Personally, I loathe having R between 1-2 (ala an M3). You can EASILY hit a "notch" when shifting from 1st to 2nd (happened to me a few times when driving an M3, as I am so used to the GM layout) & it drove me nuts. Granted, I'm certain that I'd get used to it, but what on earth for when all that needs to be done is a simple change in the layout?

Addionally, I am in 100% agreement--having R DOWN, rather then up, would be a nice improvement.

This waaayyy too expensive thing is curious to me. Compared to a Mustang, yeah it is. Compared to most other high performance cars that is cross-shopped with it, it's a bargain.

The V is middle of the road in price, and high in performance. I am wondering if we are all victims of the 'get what you pay for' syndrome. I wonder if similarly priced competitiors (GTO, SRT8) have similar problems.

That said, I applaud the effort. I was headed for an M5 until I drove the V. I would never have considered a GTO or SRT8 as a cross-shopper to the M5. The V, though, caught my attention.

Yea, compared to the M5 it is cheaper. Yes, I do applaud the effort in model year 04. In 05, start fixing the problems, don't rest on your lurals. Because it's World Seriers baseball time, I'll sum it up like this, Cadillac hit a home run in 2004 with the CTS-v, but has been hitting foul balls for 2005 and 2006.

Definitely NOT good. If everything is aligned correctly, you should not be able to do this, at least not without permanently damaging something, which would most likely cause a permanent shift problem.

Somehow you managed to find your way in between the shift gates. I would not think this is possible to 'recover' from, as you would most likely shear a roll pin or bend a shift fork or rail, etc. The stock Tremec internal shifter does have a knife edge point, but I still don't think you could force it between the gates without serious side effect.:hmm:

So, pretty much when something is wrong with the car...its GM normal...or as the "insiders" call it GMN. Yeah,....GMN, that's it..that's the ticket.

Well it is normal to a degree.

From neutral to 1st, odds are that you are at a stop, which means the output shaft and therefore the synchro is not turning. The input shaft is only turning briefly after the clutch is pressed, particularly from idle. That means that the synchro is effectively useless as there is no 'matching' that can occur, because there is no movement.

So the only matching is purely a function of the knife edge on the gear mesh and synchro hub mesh as they come together. If they happen to butt edges perfectly, so to speak like flipping a coin and it lands on the edge, it feels like it will not go into gear. If you push harder, there is a possibility that you will force it to budge enough to engage. In 1st gear it is harder to budge simply by a factor of leverage. The ratio is higher, so you have to budge back through a 3:1 ratio (not in your advantage). With a heavy duty transmission like the T56, you have heavier gears (6 of them), shafts and clutch disk, so more to rotate.

Your best bet is simply to row back to second, which will most likely rotate the countershaft via moving second gear, enough that shifting back to 1st will now be clear of the 'perfect misalignment'.

Barring that, you can just double clutch to spin the input shaft again, or let the car roll a little (if there is a slope), to move the output shaft.

I've complained to no avail the difficulty getting it into 1st (from a stop) at times in my V. I've had friends who take it for a spin straight up ask me WTF is with your CAGS in 1st - I'm like there is no CAGS!!!. 1st is impossible for me to get into every maybe 1 in 20 shifts - not near impossible, absolutely impossible - I've tried to put force on it (and double triple clutch) no dice until I roll a slight bit then it goes in but you can feel it notch halfway as it has since day one.

I'm not a fan of the t-56 at this point, and yes I've driven it in a Viper, Vette, WS6, etc.

03/04 SVT Cobra's have T-56 too. Only (big) complaint seems to be the shifter itself, which the aftermarket has addressed well. Cobra's have no solenoids I believe. The internal gearing can be quite different (between cars w/T-56's) which could account for the shifting difference in addition to the shifter, linkage, syncro's, etc.

Didn't know the WS6 had a T-56! Did the SS Z-28?

Any insight from those who have used Redline Synthetic in their trannies? How much does it help?

I have Royal Purple in mine. Personally I think it is a great improvement. Quieter, and sure seems to shift easier.

Me too, seems to run a bit cooler too.

Any thoughts re: why the UUC shifter owners are finding that there shifters don't feel like they did when new? Is it because they didn't put in the revised Lasstss bushings?

Try palming the shifter from 4th to 5th. it will naturally want to go into the propper gate, and you will NEVER grind reverse if you do it in this manner. Its faster too. Same technique applies from 2nd to 3rd. You'd be amazed at how much more accurate, and quicker this technique is.

I agree with this completely. Speedshifting and 'pushing; the shift will throw you in the wrong gate. You cannot 'direct' the shift. Letting it go its own direction and moving into gear always works pretty good.

Letting it go its own direction and moving into gear always works pretty good.I 3rd this. Sit with the car parked and slowly row through the gears. Watch how the shifter guides itself to the center. Also notice how little effort it takes to get to the 5-6 gate.

I either let the base of my palm direct the shifter up and over or I grip the shifter ball as a baseball, with most of the contact used up by my thumb and first and middle fingers. When gripping this way, the thumb is pushing the base of the ball where it meets the stalk and a snap of the wrist, clockwise, gives just the right amount of force to get into 5th.

Have i helped anyone with that explanation? Probably not. But, it's amazing how much you do things without realizing it.:hmm:
