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 my transmission, and replace the TCM with a new one from JS Benz, and Rudy. 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, First pass at the drag strip was 11.044 @ 127mph.And that was with the IAT's around 130.
I cannot reveal to you what transmission was used or what was done internally, but I can tell you there's machine 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 gear first ,second ,third ,fourth, and fifth are the same as the original SL55 transmission ,also same as the E55 tranny. again thanks to js bemz for great work. jim
