About how much do you have invested?

In this mod alone? About $125, not counting the second generation Katech short shifter that I installed two years ago.

What does the Tremec spring and Ball fix? I missed those when I did all the upgrades!

What does the Tremec spring and Ball fix? I missed those when I did all the upgrades!

Look up the Anti-venom mod for the T56. The detent assembly utilizes a captured ball and spring to give you that tactile "notch" going in and out of gears. The force required to push past that ball and spring is dependent on the strength of the spring, the condition of the ball, and (mostly) on the length of your shifter. Most people complain about the additional force required to shift following the installation of a short shifter, but they don't understand what's causing that other than the obvious loss of leverage. Now you do.

Most of the time, when people complain about trouble shifting, the root of the problem is a transmission-motor misalignment (sagging motor mounts anyone?), but if they have a really short shifter, sometimes you really need to recalibrate the strength of the detent assembly by shimming it with one or two copper 13/16" washers. Finding a lighter spring really isn't an option, unfortunately, since the spring is an odd size. In some rare cases, that captive ball has gotten corroded or otherwise jammed in the assembly and won't spin any longer, which makes it even harder to shift than Tremec intended with the stock shifter assembly length. Emphasis on "rare." Since the parts are cheap, I figured I'd get in there and replace them while I have the transmission down.

By the way, I'm sure I don't need to remind you, but take the opinions you'll find on the Anti-venom mod with a huge grain of salt. Some of the people that are reporting success are masking major transmission misalignments, and some of the people that are indifferent or entirely pooh-pooh this mod have stock length shifters. This is truly one of those situations where the statement, "your results may vary" truly applies.

I assume the B-Quiet is to reduce shifter rattle. I now have a few pieces of RAAM mat on mine. It helps.

Are these in your parts pic?, if not where can a guy get some of these?

Holy mother of .... ! You win the award for the most deteriorated shifter bushings ever. Here's where you get new ones:

Seriously. Wow. Mine were bad, but nothing compared to yours. FYI, installation of the new bushings is a bitch without some sort of lube/grease.

Will do good to know, when I do the cradle,Trans,trailing arm and motor mounts they will go in at that time.

Really? I typed "anti-venom mod" into Google and all kinds of images came up. Took five seconds.

Thanks for the pic - I was searching "Anti-venom T-56" and kept finding forum references but no good photos showing where it was at. This morning took out the "-" and the picture you showed popped up. Ah the nuances of searching...thanks for finding that and sorry for being tarded.

I will pay and handsome fee!!!!!!!!!!!!!

Those parts look awesome and remember reading some threads about the pvc side linkage.

Not to sound like an unappreciative impatient ***hole but i'm in when ya'll figure out price.

Wish I had the ability to come up with something awesome to contribute...other than money.

That center linkage arm wouldn't work. I'd bet money on that.

Can you explain more? I'm getting ready to drop my tranny and am trying to get all the info I can to get that last bit of slop out.

Center linkage arm is too short from the first post. I wouldn't go that route with the linkage arm at all. Trust me. Everything else looks good.

I'm on travel, so I don't have much time to write, but suffice it to say that the center linkage arm in my original picture is not required and would not fit anyway.

I wrote most of this up on the LS1Tech forums already, but to recap:

- Based on Cadzilla's original thread on LS1Tech, I subjected te center linkage pin to extreme scrutiny. On my shifter, the pin barely moved in its hole, so I did not feel that welding it in place was necessary.

- I replaced the plastic shifter cup with the #95 brass cup. Unless your cup is broken, it shouldn't have any effect on shifter slop. It is "merely" a durability upgrade.

- I also evaluated the "Anti-Venom" mod. After looking at the shifter detent assembly and experimenting with several copper crush washers, I came to the conclusion that any deviation from the stock design would result in very sloppy shifting characteristics. My detent ball and spring were in excellent condition. If yours is seized, I would buy a whole new assembly instead of just the ball and spring, since it's not obvious how to service the detent assembly. I looked and looked for instructions to no avail.

- The big two winners were the Home Depot mod and PISNUOFF's brass replacement bushing for the rear part of the center linkage arm. They really, really tightened up the shifter and added zero additional vibration. Advice: even though you only need four bushing pieces from Home Depot, buy 6-8. You'll find that their manufacturing tolerances result in some pieces that fit like a glove and others that are just a touch looser than you'd like. They're only like 48 cents apiece, so you can afford to buy a few extra. ;). Also, having a press on hand (e.g. a $30 bench vise) is very useful when it comes to jamming the metal cores from the stock rubber bushings into the PVC Home Depot bushings.

- The Creative Steel shifter bushings are terrible. Get the UUC ones from Luke @ Lindsay Cadillac. I bought a set of Creativr Steel ones in advance to compare to my old UUC bushings and was stunned at how poorly fabricated and soft the Creative Steel units were. They might actually be worse than stock!

So you will or will not gather these parts along with instructions for my lazy a$$ once you testing is complete?

----------

Nevermind, I guess I should have read the post all the way through. Thanks for the R&D! I already have Brian's shifter and center bushing along with the UUC bushings. I was hoping to try and clean up anything I could on the other end of the linkage.
