  48. Notice: Saturn automatic transaxle fluid (ATF), P/N 21005966 and P/N 21019223, is not compatible with this transaxle. If Saturn ATF is used, transaxle damage will result. This transaxle uses Saturn T-IV fluid P/N 22689186.

  49. Add fluid to the transaxle as necessary. Refer to the Transmission Fluid Replacement procedure located in this service manual.
  50. Start the engine and check for leaks.
  51. Important: 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. Transmission performance may be affected as new TAP values are learned.

  52. Reset the TAP values. Refer to Transmission Adaptive Functions .
