Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Transmission Fluid Change

Drain the Old Fluid
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan to drain fluid.
- Clean the pan and magnet of any debris.
Replace the Filter
- Remove the old transmission filter.
- Install a new filter, ensuring it is seated properly.
Reinstall the Transmission Pan
- Apply a new gasket or sealant to the pan.
- Reinstall the pan and torque the bolts to the manufacturer’s specifications (typically around 12-15 ft-lbs).
Refill Transmission Fluid
- Use a funnel to add the correct type and amount of transmission fluid (consult the owner's manual for specifications).
- Start the engine and let it warm up; check the fluid level and add more if necessary.

3. Throttle Position Sensor Adjustment/Replacement

Remove the Throttle Body
- Disconnect the intake duct and remove any electrical connectors.
- Unbolt and carefully remove the throttle body from the intake manifold.
Inspect and Clean
- Clean the throttle body with throttle body cleaner.
- Check the TPS for proper resistance values using a multimeter.
Reassemble
- If replacing the TPS, install the new one.
- Reattach the throttle body and intake duct, ensuring all bolts are torqued properly.

4. Check Engine Mounts

Visual Inspection
- Inspect engine and transmission mounts for cracks or wear.
- Replace any damaged mounts with OEM parts.
Installation
- Remove the old mounts and install the new ones, ensuring they are torqued to specifications.
