Hi Jeff, I have a 2016 Silverado with the 5.3 and the 8 speed transmission. Also since the transmission is different the gearing and tuning are naturally different. ! This suggests that the idler gear and ball bearing assembly has a tight interference fit to the stator shaft support housing. If the transmission fluid is discolored or has evidence of debris in the fluid, it would be recommended to replace the torque converter and flush the system to complete this repair. Internal hydraulic leakage, hard part failures and contaminated/failed solenoids are all issues that can plague units, some more than others. We had to use a spacer from Advanced Adapters but otherwise they are the same. The customer approves a teardown.

While not new to the 6L80, it uses an Input Speed Sensor to monitor input speeds to compare against engine speed and Output Shaft Sensor speed, using this data to adjust shift speeds under instantly detectable conditions. However some 2wd vans and HD truck versions had a, J Series Trucks & Wagons, (I6 But the cause he discovered was related to the pump. However, if you look beyond the outside of the front covers of TMBX and JMBX and look inside the units, the similarity quickly disappears. and the maximum output torque is 664 ft. lbs. 3-Bolt Adapter Flange Yoke Kit.
