Shift Linkage Check
Check for a misadjustment in shift linkage by matching the detents in the transmission range selector lever with those in the transmission. If they match, the misadjustment is in the indicator. Do not adjust the shift linkage.

Hydraulic leakage at the manual control valve can cause delay in engagements and/or slipping while operating if the linkage is not correctly adjusted.

Check TSBs
Refer to all Technical Service Bulletins (TSB)s that pertain to the transmission concerns, and follow the procedure outlined.

Carry out On-Board Diagnostics
After a road test, with the vehicle warm and before disconnecting any connectors, carry out the Quick Test using the diagnostic tool. Refer to Computers and Control Systems
