Code P2862 Description

The Automatic Transmission Adaptive Learning feature is designed to increase durability and provide a consistent shift feel over the life of the vehicle. A new vehicle or transmission may have firm shifts, soft shifts, or both. This operation is considered normal and will not affect the function or durability of the transmission. Over time, the adaptive learning process will fully update transmission operation. Additionally, whenever the battery is disconnected or a new battery installed, the strategy must be relearned. The Adaptive Learning procedures require a factory Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS).
