Visual Inspection

Visual Inspection
This inspection will identify modifications or additions to the vehicle operating system that may affect diagnosis. Inspect the vehicle for non-Ford factory add-on devices such as:
^ Electronic add-on items:
- air conditioning
- generator (alternator)
- engine turbo
- cellular telephone
- cruise control
- cb radio
- linear booster
- backup alarm signal
- computer
^ Vehicle modification:

These items, if not installed correctly, will affect the transmission control module (TCM) or transaxle function. Pay particular attention to add-on wiring splices in the TCM harness or transaxle wiring harness, abnormal tire size or axle ratio changes.
^ leaks.
^ correct linkage adjustments.

Shift Linkage Check
Check shift linkage adjustment by matching the detents in the transaxle range selector lever with those in the transaxle. If they match, the error is in the indicator. Do not adjust the shift linkage.

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

Check TSBs
Refer to all TSBs which pertain to the transaxle concern and follow the procedure as outlined.

Carry Out On-Board Diagnostics (KOEO, KOER)
After a road test, with the vehicle warm and before disconnecting any connectors, carry out the Quick Test using diagnostic tool. Refer to Computers and Control Systems for diagnosis and testing of the powertrain control system.
