Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Transmission Fluid Change

a. Drain Transmission Fluid
- Locate the transmission drain plug and remove it using a socket wrench.
- Allow the fluid to completely drain into a pan.
b. Replace Transmission Filter (if applicable)
- Remove the transmission pan (if applicable) using a socket set.
- Replace the old filter with a new one, ensuring the gasket surface is clean.
c. Refill Transmission Fluid
- Reinstall the transmission pan and torque the bolts to manufacturer's specifications.
- Use a funnel to refill the transmission with the recommended fluid type (check owner’s manual for specifications).

3. Inspect and Replace Damaged Components

a. Check the Throttle Position Sensor
- Disconnect the TPS connector and use a multimeter to test its resistance and voltage output.
- If faulty, replace it with a new unit.
b. Inspect Transmission Mounts
- Check the transmission mounts for cracks or signs of failure.
- If damaged, replace with OEM parts.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature.
Test drive the vehicle to ensure normal shifting behavior.
