DELAYED SHIFT - GDS ANALYSIS
DESCRIPTION:
If you are servicing a 6-speed automatic transaxle with a harsh and/or delayed shift, follow the Diagnostic Procedure shown.
DIAGNOSTIC PROCEDURE:
1. Check the ATF level when the engine is idling in "P" according to TSB 10-AT-001-1. Adjust the ATF level as needed.
2. Reset and relearn the adaptive values according to TSB 09-AT-002-1.
3. Compare to a similar model and year vehicle. If the shift delay is noticeably longer than the comparison vehicle, continue with the diagnosis.
