Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Funnel, transmission fluid pump, clean rags.
Remove the transmission dipstick and check the fluid level; add fluid if low.
If the fluid is dark or has a burnt smell, drain the fluid using a transmission fluid pump.
Replace with the manufacturer-recommended transmission fluid (e.g., Toyota ATF WS).
Reinsert the dipstick and check the level again after adding fluid.

3. Replace Transmission Filter

Tools Required: Socket set, torque wrench, replacement transmission filter, new gasket, and transmission fluid.
Remove the transmission pan by unscrewing the bolts (be prepared for fluid spillage).
Take out the old transmission filter and replace it with the new one, ensuring the gasket is properly seated.
Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications.

4. Inspect and Replace Transmission Solenoids

Tools Required: Socket set, multimeter.
Locate the transmission solenoids (usually found inside or on the valve body).
Disconnect the electrical connectors and remove the solenoids.
Test each solenoid with a multimeter for resistance; replace any solenoids that are out of spec with new ones.
Reinstall the solenoids and connectors.

5. Check and Replace Transmission Mounts

Tools Required: Socket set, jack and jack stands.
Support the transmission with a jack and remove the transmission mount bolts.
Inspect for cracks or damage; replace if necessary.
Reinstall the new mount and torque the bolts to specifications.
