Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down before working on the transmission.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, drain pan.
Remove the transmission fluid pan using a socket set. Ensure to have a drain pan underneath to catch fluid.
Inspect the old fluid; if it is dark or burnt, it needs replacing.
Replace the transmission filter by unbolting it and installing a new filter.
Reinstall the transmission pan with a new gasket, torquing to manufacturer specifications (typically around 10-12 ft-lbs).
Fill the transmission with new fluid (consult the owner’s manual for the correct type and capacity, usually Toyota ATF WS).

3. Inspect and Adjust Shift Linkage

Tools Required: Wrench set, screwdriver.
Visually inspect the shift linkage for any signs of wear or misalignment.
Adjust the linkage as necessary to ensure proper engagement.
Test the linkage movement by manually shifting through the gears to check for smooth operation.

4. Check for Transmission Solenoid Issues (if applicable)

Tools Required: Multimeter, socket set.
Check the resistance of the transmission solenoids with a multimeter. Refer to service manual for specific resistance values.
Replace any faulty solenoids by unbolting them from the valve body and installing new ones.
