⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening the transmission pan to prevent burns.

Symptoms

•The vehicle unexpectedly shifts out of gear while driving
•Engine RPMs increase without a corresponding increase in vehicle speed
•Transmission warning light may illuminate on the dashboard
•Harsh or slipping sensations when attempting to accelerate

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe it clean, reinsert it, and pull it out again to check the fluid level.
3. If low, add the correct type of transmission fluid as specified in the owner's manual (usually ATF).
4. If fluid is dark or has burnt smell, proceed to drain and replace it.
5. Remove the transmission pan using a socket set, allowing fluid to drain into a container.
6. Replace the transmission filter if applicable, following the manufacturer's specifications.
7. Reinstall the transmission pan and torque bolts to the specified values.
8. Refill the transmission with new fluid through the dipstick tube.

3. Inspect and Repair Transmission Control Module (TCM)

Sub-steps:
1. Locate the TCM, typically found near the transmission.
2. Disconnect the electrical connectors; inspect for corrosion or damage.
3. Use a multimeter to check for proper voltage and ground at the connector.
4. If defective, replace the TCM with a new unit, ensuring proper programming as per manufacturer guidelines.
5. Reconnect all connectors securely.

4. Adjust Shift Linkage

Sub-steps:
1. Locate the shift linkage assembly.
2. Inspect for any looseness or misalignment.
3. Adjust the linkage according to the service manual specifications to ensure proper engagement.
4. Test the linkage by shifting through all gears without the engine running.
