Has anyone tried one of these transmission mount inserts from revshift ?

If so, is it worth the $50, and do you need to remove the trans mount from the car to install it ?

also, any more noticeable vibrations ?

Thanks.

I'm assuming that this will get rid of some of the flex in the drive-line and also help with the wheel-hop too,
the axles are great, but there is still a little more room for improvement.

I'll buy one shortly, getting motor mounts and other work taken care of first.

Are you insane? It's rubber. Putting it in the freezer is not going to help you--in fact, it's going to hurt you. Big time.

Isn't it a polyurethane; more of a plastic.


Anyways... Got mine on order

 

[SevillianSTS]

How much more work would be involved in just removing the stock mount to press this insert into it ?

 

[SevillianSTS]

Hmmm.... wonder if you should grind it down a little, so its not quite as tall.

Dealer is finishing up my car then I have to work Thurs and Fri, so I'll probably put mine in on Sat.

Fuzzy, yours still working out fine ?

I do still have the stock shifter in, UUC on the way planning on installing this insert first, so i'll be able to compare the insert with both shifters.

Just put mine in, got home from work and couldn't wait until tomorrow.... well "today" now.

info on car:
new trans has 700 miles on it
stock motor mounts installed by dealer yesterday
stock shifter, for now... UUC on the way
Borla cat back exhaust -pretty mellow until you get on it quite a bit.
GForce axles


I like it. It does change the feel of the shifter slightly. I think it may have helped with my wheel hop a little more also. Reverse is easier to get into; wasn't difficult with the new trans... but its even easier now. I feel zero additional vibrations, quarters in my little change holder by the cup holders did not make a sound while on my test drive. Shifter sits perfectly still also, while driving and when idling.

I do think the car "seems" louder now though, just a little, only noticeable when the windows are up. I hear the exhaust more... not that it is bad.
Either it is transmitting the sound, or maybe lifting the trans to install moved my exhaust around a little and I need to re-tighten.

For sure overpriced; but if I was making these and selling them.... I'd probably charge 50 bucks too.

 

[SevillianSTS]

Yes, car definitely sounds different, you guys think its the insert ? or do I need to get under there and check for exhaust leaks. I'll probably check anyways, but figured I'd get some opinions too.

thanks

Revshift Transmission mount insert + UUC short shifter = pure driving bliss
I know that pissnuoff's shifter has a lot of good reviews, but I didn't want the "super" short throw, this is perfect.

I checked my exhaust and did find a small leak. The trans insert does transmit a little more of my borla's sound into the car; nothing wrong with that... I'm just giving my two cents for anyone thinking about the insert. No extra vibrations. Shifter sits perfectly still.
Shifter is so precise... and I've only driven it a mile or two so far. Time for bed.... :cloud9:

 

[SevillianSTS]

Hate to say this... but I toook the insert out to see how I liked the car with just the UUC shifter + shifter bushings.

I think I like it better without the revshift insert, with the insert gears 1 and 3 are so smooth at the expense of 2 and 4 being MORE notchy. Not terrible, but the short shifter was a huge improvement while the insert... i'm not sure. BTW, I have brand new stock motor mounts in.

Thinking about sanding the insert down a little and putting it back in, I like the idea of supporting the trans mount, but it seemed to me that this is so tall that it takes on all the support. I say this because with it in, the rubber on the trans mount was soft since this was sandwiched in there. Seems I would want the trans mount to still be supporting the trans a little.

I also recently installed this and at first had a LOT more vibration in the car, which settled down a little bit over the last few days. It did mostly resolve my issue with "finding" Reverse and some notchiness when shifting all gears, but made it harder to use 6th gear (who needs 6th anyway ...). My main issue is the amount of noise I'm getting in the cabin from the engine/exhaust, which seems to have gotten much louder and much more rumble in my seat since installing the insert. I double-checked the header band clamps which are right under my seat and they don't appear to be leaking, so I'm assuming that it's just the insert transmitting sound into the car. I'm usually not against "louder", but this isn't louder in a good way, it sounds like a giant sewing machine at 3K RPM, rather than a rumbling beast and was fairly quiet without much vibration before the insert. I'm debating taking it out to see which way I prefer, since it's so easy to install after you know how to do it.

Just curious, how did you take it out? Any tips you can share? I was thinking of using a c-clamp and some small blocks to push it back out.

Thats interesting.. because I put my insert in right after the dealer replaced the stock motor mounts; and same results.

As far as removing it, I remember using the hammer again as a lever, and a screwdriver, and probably something else to help push it out; don't remember exactly.

On the stock mount, what holds the rubber to the metal plates ?

I have the insert in there, but 1st and Reverse do not seem to slide in like I remember when I first installed the insert. Trans has been replaced since; insert is still in there. Just wondering if the rubber is separating from the mount.

 

[SevillianSTS]

Even if the rubber separated, it is all held together by gravity and that big center pin.

I kinda thought so; figured I'd check with you guys too though. Din't know if it could shift around or anything.
Seems as I'm slowing to a stop, if I push to 1st just before stopping it pops right in; if I complete stop there's just a little more effort needed.
No issues though, just curious. Thanks.

I few words about the Creative Steel mount. It appears to be good quality in its construction. The polyurethane is softer, it gives a little when I push on it hard with my fingernail, the Revshift I couldn't make an indention. This is logical as the CS mount is 40 hardness and the Revshift is 80. The holes properly aligned with the transmission and the studs on the bottom were straight, aligned easily in the support and had plenty of length.

PLEASE NOTE: I am not saying the Revshift is a poor product or inferior construction! I am completely satisfied with their motor mounts and am considering using some of their bushings.

I installed the the transmission mount and tested it out. The quality of the shifting is still good and it goes into reverse easily. There are no new or noticeable vibrations, similar to the revshift once it "broke in."

The biggest difference is in the sound. There is no more spinning sound from the transmission or gear clicking sounds as I mentioned in my earlier post. The car is much quieter throughout the RPM range, though not back to the Cadillac quiet with the original mount. I can hear the radio better at highway speeds and don't have any reverberating or droning sounds.

The important thing is that, for my use, it is quiet enough. I think I had realistic expectations. I did not expect to obtain stock sound levels, but rather reduce the noise to a level tolerable to me. If this was a pure play car or a track car these would not have been issues for me. The CS mount gave me a good blend of accurate shifting and low noise/vibration levels.

Hope this helps anyone debating the two and what they are using it for!

Do you think there is any difference in shifter movement between the CS Mount, and the RevShift insert ?

I'm less concerned with noise and more interested in smoothest fluid shifting.

Update:

I swapped my stock mount with insert, out for the creative steel mount. (been in for a few weeks now; wanted to thoroughly test it before giving the update)

Gotta say I think it is the best of both worlds. I didn't like how the revshift insert made 1st and reverse feel better at the expense of a notchier 2nd and 4th.

Even after letting the insert "settle in" for a while (months) I like the sound with the creative steel better. I still hear the growl of the engine under load through it, but not so much droan as before.

Shifter feels nice and solid, and all my gears feel equally easy to move to.


The insert is not a bad product by revshift, I just favor this new mount more.

Installed the Revshift trans mount over the weekend. So far so good, tad bit tighter between shifts. I have a B&M shifter which is already a bit noisy but not bad. Now under acceleration it's much louder in 1st & 2nd. Not very happy about it. May look into PISNUOFF's shifter next.

I felt the same way. It helped the shifts, but was louder.

Creative Steel complete replacement mount was the best of both worlds for me.
