Solution

1. Preparation

Gather necessary tools: socket set, OBD-II scanner, multimeter, fluid pump, and drain pan.
Ensure the vehicle is parked on a level surface, and the engine is cool.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, then remove it again to check fluid level; add fluid if low.
Inspect the fluid's color and consistency. If dark or burnt, proceed to fluid replacement.

3. Change Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set, and lower the pan carefully.
Clean the pan and magnet, removing debris and metal shavings.
Replace the transmission filter if applicable.
Reinstall the pan with a new gasket, tightening bolts to manufacturer specifications (typically around 10-12 ft-lbs).
Fill the transmission with new fluid using the appropriate type (typically Toyota ATF WS).

4. Inspect and Adjust Linkage

Locate the transmission linkage and check for any signs of wear or damage.
Adjust the linkage according to the specifications in the service manual, ensuring proper alignment.

5. Test Transmission Solenoids

Disconnect the electrical connectors from the solenoids.
Use a multimeter to check the resistance of each solenoid; compare results to manufacturer specifications.
Replace any solenoids that are outside of specification.

6. Recheck Fluid Level and Test Drive

After repairs, recheck the transmission fluid level and top off if necessary.
Perform a test drive to ensure smooth shifting and no hard shifting issues.
