Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety gloves and goggles.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check fluid level.
If low, add the appropriate transmission fluid as specified in the owner's manual.
If dirty or burnt, drain and replace the fluid.

3. Inspect Transmission Components

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the transmission and surrounding areas for leaks.
Check the condition of the transmission mounts; replace if cracked or worn.

4. Test Transmission Solenoids

Locate the transmission solenoids based on the vehicle's service manual.
Using a multimeter, check the resistance of each solenoid according to specifications.
Replace any solenoids that are outside the specified range.

5. Examine Driveshaft and CV Joints

Inspect the driveshaft and CV joints for any signs of wear or damage.
Check for play in the joints by moving them back and forth.
Replace any damaged components as necessary.
