1. The above items, if not correctly installed, will affect PCM or transaxle function. Pay particular attention to add-on wiring splices in the PCM harness or transaxle wiring harness, abnormal tire size, or axle ratio changes.

2. Leaks. See Component Tests and General Diagnostics.

3. Correct linkage adjustments. See Adjustments.

Selector Lever Linkage Check

Check for a misadjustment in the selector lever linkage by matching the detents in the transaxle range selector lever with those in the transaxle. 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 engagement and/or slipping while operating if the linkage is not correctly adjusted. Correctly adjust the selector lever linkage. See Adjustments.

Check TSBs and Mazda Tips

See all Technical Service Bulletins (TSBs) and Mazda Tips messages which pertain to the transaxle concern and follow the procedures as outlined.

Carry Out On-Board Diagnostics

After a road test, with the vehicle warm and before disturbing any connectors, carry out the quick test using the scan tool. See Component Tests and General Diagnostics.
