Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check fluid level.
If low, add the appropriate transmission fluid (consult the owner's manual for specifications).
If fluid is discolored or smells burnt, consider a fluid change.

3. Inspect Transmission Components

Raise the vehicle securely with jack stands.
Visually inspect the transmission fluid lines for any leaks or cracks.
Check the condition of transmission mounts; replace if cracked or damaged.

4. Test and Replace TCM

Use a multimeter to test the TCM for proper voltage and signal output.
If malfunctioning, remove the old TCM and install a new one, ensuring all connectors are secure.

5. Inspect Throttle Position Sensor

Locate the TPS on the throttle body.
Disconnect the TPS connector and use a multimeter to check for proper resistance values according to manufacturer specifications.
Replace the TPS if out of range.
