- Summary
- "15396 - service update. This bulletin provides a service procedure to install the original design temperature-sensor wiring harness to the valve body on certain 2015 model year cadillac escalade and escalade esv; chevrolet silverado; and gmc sierra, yukon, and yukon xl vehicles. The supplier of the transmission-wiring harness introduced an unapproved change to the temperature sensor (thermistor), resulting in incorrect oil-temperature readings during transition from cold to warm temperatures. This could cause a harsh shift when starting the vehicle at temperatures below 32ºf (0ºc); however, shift quality improves once the transmission oil warms up."
Owners of these vehicles have filed 249 complaints in the transmission category.
