Update:
The T56 i have (TUET2190AD) is from an 2005 Ram SRT-10; confirmed by Tremec, Rockland Standard and local Dodge dealer.
There appears to be a lot of misinformation out there regarding the difference in The Ram SRT-10 and Viper T56 (and all T56's). According to Tremec and Rockland Standard, there are a few differences.
There are two types of SRT-10 trannies: I have an early model which is basically a Viper transmission with a different tailhousing (WITHOUT SPEED SENSOR), larger output shaft, yoke and a .80 and .63 (+/-+) overdrive. The later model trans has an upgraded second gear (stronger material and higher gear) and has different gear overdrives.
I need a speed sensor (or mechanical drive) so i need to swap the tailhousing to a viper, or trade my trans...not sure what im gonna do. If anyone has a viper tailhousing they want to get rid of, i need it!
Thanks for everything guys!
