As most of you know, I recently changed my differential ratio, from 3.07 to 3.27. after having lots of trouble with the tcm and the tranny,,,, Rudy, ( the builder of my car) send me a tcm, that actually worked, and did not cause my transmission to slip between second and third,(that tranny is now toast) because of that , I had to rebuild (replace) my transmission, and replace the TCM with a new one from Rudy, and I am now running the 3.27 gears, There is no more limp mode, there is no more slipping between second and third., there is no more problems whatsoever with the transmission or the TCU, (track time) First pass was 11.044 @ 127mph.And that was with the IAT's around 130. Backed that up with 11.49 @ 126 mph
I cannot reveal to you the new transmission used or what was done internally, but I can tell you there's a lot of work and a whole bunch of extra clutches. I can also tell you, externally there is a small mod to be made so that it fits in the car.
The transmission gears,,, first ,second ,third ,fourth, and fifth are the same as the original srt6 tranny ,when the V8 was installed we used the SL55 transmission ,also same as the E55 tranny. jim

example
The limited has the smallest amount of clutches
the srt6 has more than the limited but less than the sl,or E55
the transmission that Rudy used has more clutches and is better than all the above

 

That's the fastest 1/4 mile pass I've seen so far.
Would love to find a TCU tune that wouldn't put any expensive parts at risk.

 

Thanks for the kind words Jim. The trans is built like a brick **** house and should take all the punishment you can throw at it. Between that, the modified valve body, blue tops and the TCU software upgrade, it shifts is very pronounced and firm at WOT but isn't too harsh while just driving around town.

I'd like to clarify though that the gear change TCU and trans software upgrade was handled by Marcin at Speedriven and I'm very happy with how it performs.

Also, have to say I had a blast while we were down there and ripping your car down the track was a truly unique experience I will dream about for a good long while. Looking forward to getting down there again soon and getting you into the tens!

 

Nice work Rudy....you and Speedriven are making some nice progress in the tranny area....

 

Nice job, guys!!!!!
