  66.  
  67. Inspect the transaxle fluid level.
    NOTE
    It is recommended that Transmission Adaptive Pressure (TAP) information be reset. Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, the ECM, PCM or TCM will need to relearn TAP values. Transaxle performance may be affected as new TAP values are learned.

  68.  
  69. Reset the TAP values.
  70.  

The 4T45 automatic transaxle uses a line pressure control system, which has the ability to continuously adapt the system line pressure. This compensates for normal wear of clutch fiber plates, seals, and springs.

The Transmission Control Module (TCM) maintains the Upshift Adapt parameters for the transaxle. The TCM monitors the Input Speed Sensor (ISS) and the Output Speed Sensor (OSS) during commanded shifts in order to determine if a shift is occurring too fast or too slow. The TCM adjusts the signal from the transaxle Pressure Control (PC) solenoid in order to maintain a set shift feel. Transaxle adapts must be set again when the transaxle is overhauled or replaced. In order to set the transaxle adapts again, select the following:
