Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and securely lifted if needed.
• Disconnect the negative battery terminal 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 the fluid level.
• If low, add the appropriate type of transmission fluid (refer to owner’s manual for specifications).

3. Inspect and Repair Wiring

• Visually inspect the wiring harness connected to the TCM for any damage.
• Repair any frayed or broken wires using solder and heat-shrink tubing as necessary.
• Ensure all connectors are fully seated and free of corrosion.

4. Replace Transmission Control Solenoids (if necessary)

• Remove the transmission pan by unscrewing the bolts with a socket set.
• Drain the transmission fluid into a pan.
• Unbolt and remove the solenoids from the valve body.
• Install new solenoids, ensuring they are seated properly and tighten to manufacturer specifications (typically around 8-10 ft-lbs).
• Reinstall the transmission pan with a new gasket and torque the bolts to manufacturer specifications.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and perform a road test to ensure proper shifting and operation.
• Monitor for any error codes using the OBD-II scanner.
