DISCUSSION:

The 948TE automatic transmission uses a shift algorithm, that includes learned information so that the shift quality remains, even as the transmission wears. This learned information is recorded in memory cells, referred to as “Adaptation Memory Cells”.

Each applied clutch records the amount of time it takes to fill the clutch (Fast Filling Counter/Filling Time) and the amount of pressure (Filling Counter/Filling Pressure).

The adaptation memory cells are set to zero (0) on every new transmission (new in vehicle and/or replaced for service) and when the transmission control module is replaced for service. In addition, the adaptation memory cells are set to zero (0) anytime the transmission control module is flashed and when the transmission control module adaptation memory cells are cleared using the wiTECH diagnostic scan tool (Quick Learn/Valve Body Solenoid Learn).

Until the adaptation has been learned/relearned, the transmission shift quality may not meet the customer’s expectations.
