Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, transmission fluid pump, funnel.
Carefully remove the transmission pan if necessary to inspect fluid condition.
If fluid is low or contaminated, drain the existing fluid completely.
Replace with the manufacturer-recommended transmission fluid (check owner's manual for specifications).
Reinstall the transmission pan and torque bolts to the specified value.

3. Replace Transmission Filter (if applicable)

Remove the transmission pan (if not done in the previous step).
Locate and remove the old transmission filter.
Install the new transmission filter, ensuring it is seated correctly.
Reattach the transmission pan.

4. Inspect and Replace Transmission Mounts

Tools Required: Jack, jack stands, socket set.
Support the transmission with a jack.
Remove the bolts securing the transmission mount to the chassis.
Replace with a new mount and torque to the specified value.
Recheck alignment and ensure the mount is securely fastened.

5. Throttle Position Sensor Adjustment or Replacement

Disconnect the TPS connector.
Use a multimeter to check resistance and voltage output according to specifications.
If faulty, replace the TPS with a new unit.
Reconnect the wiring harness and ensure it is secure.
