Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported.
Disconnect the battery to avoid electrical shorts.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back and remove it again to check fluid level; add fluid if low.
If the fluid is dark, burnt, or contaminated, proceed to replace it:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and gently pry the pan loose.
- Allow old fluid to drain completely.
- Remove the old filter and replace it with a new one.
- Clean the transmission pan and replace the gasket.
- Reinstall the pan and torque bolts to manufacturer specifications (typically around 10-15 ft-lbs).

3. Inspect and Replace Throttle Position Sensor (if necessary)

Locate the TPS, usually mounted on the throttle body.
Disconnect the electrical connector from the TPS.
Remove the screws or bolts holding the TPS in place.
Install the new TPS in the same position and secure it.
Reconnect the electrical connector.

4. Inspect Transmission Mounts

Visually inspect the transmission mounts for cracks or excessive wear.
If damaged, support the transmission with a jack.
Remove the bolts securing the mount to the transmission and chassis.
Replace with a new mount and torque bolts to specifications.
