Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery cable to prevent electrical shorts.

2. Fluid Change

Tools Required: Socket set, fluid pump, transmission fluid.
Remove the transmission drain plug and allow the old fluid to drain completely.
Replace the drain plug and torque to manufacturer specifications.
Refill with the recommended transmission fluid using a fluid pump until it reaches the proper level.

3. Solenoid Replacement (if faulty)

Tools Required: Socket set, torque wrench, new transmission solenoids.
Remove the transmission pan by unscrewing the bolts carefully.
Drain any residual fluid from the pan.
Locate the solenoids, disconnect the wiring harness, and remove them from their mounting.
Install new solenoids, ensuring they are seated properly, and reconnect the wiring.
Reinstall the transmission pan and torque bolts to the specified value.

4. TCM Reset (if applicable)

Tools Required: OBD-II scanner.
Reconnect the negative battery cable.
Use the OBD-II scanner to reset any trouble codes related to the transmission.
Perform a soft reset of the TCM by turning the ignition on without starting the engine, allowing it to sit for 10 minutes.
