GM Bulletin No.: 15396A Date: September 2015 Service Bulletin SERVICE UPDATE SUBJECT: Service Update for Inventory and Customer Vehicles Harsh Shift When Starting in Low Temperatures Expires with Base Warranty MODELS: 2015 Cadillac Escalade, Escalade ESV 2015 Chevrolet Silverado 2015 GMC Sierra, Yukon, Yukon XL Equipped with 6.2L Engine (L86) and 8-Speed Automatic Transmission (M5U) This bulletin is revised to update the Parts Information. Please discard all copies of bulletin 15396. This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason. This bulletin will expire at the end of the involved vehicle's New Vehicle Limited Warranty period. PURPOSE 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, equipped with a 6.2L engine (L86) and 8-speed automatic transmission (M5U). 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. This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer for any type of service during the New Vehicle Limited Warranty coverage period. VEHICLES INVOLVED All involved vehicles are identified by VIN in the Global Warranty Management System – Investigate Vehicle History Application. Dealership technicians should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content. Additionally, a list of involved vehicles currently in dealer inventory is available on the “Service Update Bulletin Information” link under the “Service” tab in GM GlobalConnect (US) or attached to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty should also be checked for vehicle eligibility. Copyright 2015 General Motors.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.
