1. Vehicle modification
2. Electronic add-on items:
- Air conditioning
- Generators
- Engine turbo
- Cellular telephone
- Cruise control
- CB radio
- Linear boosters
- Backup alarm signals
- Computer
3. The above items, if not correctly installed, will affect powertrain control module (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.
4. Leaks. For additional information, refer to LEAKAGE INSPECTION.
5. Correct linkage adjustments. For additional information, refer to Automatic Transmission/Transaxle; Shift Cable, A/T.

Shift Linkage Check
Check for a misadjustment in the shift 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. For additional information, refer to Automatic Transmission/Transaxle; Shift Cable, A/T.

Check TSBs and Mazda Tips
Refer to all Technical Service Bulletins 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.
