Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues during repairs.

2. Check and Replace Transmission Fluid

Fluid Level Check:
- Remove the transmission dipstick and wipe it clean.
- Reinsert and remove the dipstick again to check fluid level.
Fluid Replacement:
- Use a wrench to remove the transmission pan bolts.
- Carefully lower the pan and drain old fluid into a container.
- Replace the transmission filter if needed.
- Clean the pan and the magnet inside for metal shavings.
- Reinstall the pan with a new gasket and torque bolts to specifications (usually around 8-10 ft-lbs).
- Refill with new transmission fluid (consult owner’s manual for specific type and quantity).

3. Inspect and Repair Transmission Control Module

TCM Testing:
- Reconnect the battery and use a multimeter to check TCM voltage and ground connections.
- Replace the TCM if it fails to meet specifications.

4. Adjust or Replace Linkage

If linkage is misaligned or damaged:
- Loosen the adjustment nuts and reposition the linkage.
- Tighten the adjustment nuts to specifications.
- If damaged, replace the linkage components.
