i'm using a 3.29 diff. or will be. iirc...get it from a newer 98-02ish 3800/3100 non-supercharged 4t65e. the S/C uses the sprockets to change the FDR to 2.93. i'm looking for tranny label codes now and that will tell me everything.

he 4T65-E was introduced to replace the 4T60-E in 1997. The 4T65-E included a larger 258 mm torque converter and many other changes to improve reliability. It is able to handle vehicles up to 6500 lb (2948 kg) GVWR with up to 280 ft·lbf (380 N·m) of torque. A number of final drive ratios are available, with many distinct models. Starting in mid year 2000 models, all 4T65-E models received an upgraded valve body. Starting in 2003 the internal electronics were changed, and ratcheting springs for input and 3rd gear were added.
