GM 4T60-E Transmission - 4T65-E

The 4T65-E was introduced to replace the 4T60-E in 1997. The 4T65-E included a larger 258 mm torque converter for some models 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, hardened 4th gear shaft, ratcheting sprags for input and third gear were added. The last application was the 2011 Chevrolet Impala as GM has transitioned to the 6T70 family transmissions for 2012.
