Solution

1. Preparation

Gather all necessary tools and parts for the repair.
Disconnect the battery to ensure safety while working on the vehicle.

2. Transmission Fluid Replacement

Tools Required: Fluid pump, drain pan, socket set, funnel, new transmission fluid.
Remove the transmission drain plug and allow old fluid to fully drain into the pan.
Replace the drain plug and torque to manufacturer specifications.
Using a funnel, add new transmission fluid through the dipstick tube or fill port until it reaches the recommended level.
Start the engine and cycle through the gears to circulate the fluid, then recheck the fluid level.

3. Replace Sensor(s) (if applicable)

Tools Required: Socket set, screwdrivers.
If the TPS or MAF is faulty, locate the sensor and disconnect the wiring harness.
Remove the screws or bolts securing the sensor and gently remove it from its mounting.
Install the new sensor by reversing the steps, ensuring a secure fit and reconnecting the wiring harness.

4. Inspect and Replace Mounts (if necessary)

Tools Required: Jack stands, socket set.
Safely raise the vehicle and support it with jack stands.
Inspect the transmission and engine mounts for cracks or excessive wear.
If damaged, remove the old mounts by unbolting them and install new mounts, ensuring they are properly torqued to specifications.
