Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical shorts.

2. Fluid Change

Tools Required: Transmission fluid pump, wrench set, drain pan.
Drain the old transmission fluid by removing the drain plug and let it completely empty into a drain pan.
Replace the transmission fluid filter (if applicable) by removing the access cover and the old filter.
Install the new filter and gasket, ensuring a proper seal.
Reinstall the drain plug and refill the transmission with the manufacturer-recommended fluid type and quantity.

3. TCM Inspection

Tools Required: Multimeter, socket set.
Remove the TCM from its mounting location, ensuring to disconnect any wiring harnesses carefully.
Test the TCM according to the manufacturer's specifications for voltage and continuity.
Replace the TCM if any faults are detected, reassembling it carefully.

4. Throttle Position Sensor Check

Tools Required: Multimeter, socket set.
Disconnect the TPS connector and test the voltage output using a multimeter.
If the readings are outside of the specified range, replace the TPS.
Reconnect the TPS and clear any error codes if previously stored.
