I'm not feeling a big difference between the new TR 6060 transmision in my Z06 vs the T-56 that is in my Viper. I mean don't get me wrong. The 6060 does shift A LITTLE BIT more crisp, but it's not a world of a difference like some folks have said. So does anyone else here share the same feelings?
I notice a huge difference as well. I believe that the vette has some stupidly long linkage which makes the transmission feel a fit muddy when shifting.
There is simply no comparison between the t56 and the tr6060. The 60 feels so much better and shifts smoother. As soon as the t56 craps out in the turbo car then the 6060 is going in unless something else better comes along.
A little off topic, but has anyone driven a Viper with a Donato built T-56? The reason I ask, is because DC Performance is going to swap out my stock T56 for a Donato re-built one with close 5th and 6th ratio gears..
1tony1 used the same clutch he had for the t56. The stock 08+ clutch is twin disk but the transmission does feel noticeably different even without clutch. The throw is probably 35-40% shorter and it seems very unlikely that you could do the damaging 3rd to 2nd gear shift. I had this problem a couple of times in my 97 about 12 years ago.
Using a Mcleod street twin with the TR6060, we had to shim things a bit. Not sure how much, but it was needed. For the Gen 3, if you get the TR6060 you'll also need the driveshaft for the TR6060 or you will need to shorten your 03-06 driveshaft. Other than that, it's a direct replacement.
Tony installed the 6060 in my '96 and it's a world of difference. I have the SPEC stage III clutch...not the twin disc. SImms, you can drive mine in a few weeks and see what you think.
SRT guys posted something on this yesterday. Might want to review it, but I think they said it would shift smoother with the Dextron IV in the trans vs the 75-85W Castrol gear oil.
