- Summary
- 15389 - service update. This bulletin provides a service procedure to reprogram the transmission control module (TCM) on certain 2015 model year cadillac escalade, escalade esv, chevrolet silverado, gmc sierra, yukon denali and yukon denali xl vehicles equipped with an 8l90 8-speed (m5u) transmission and 6.2l (l86) engine. These vehicles may have a condition in which transmission calibration allows a higher than target energy input to the torque converter clutch (tcc) under certain conditions. This may lead to faster than expected torque converter clutch material wear, and a shudder feeling when the tcc is applied.
Owners of these vehicles have filed 329 complaints in the transmission category.
