Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to prevent electrical shorts during the repair process.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, 10mm socket, torque wrench.
Remove the transmission pan using a 10mm socket, ensuring to catch any fluid in a drain pan.
Inspect the pan for metal shavings or debris.
Replace the transmission filter as needed.
Clean the pan and apply a new gasket.
Reinstall the pan and torque the bolts to the manufacturer's specifications (usually around 8-10 ft-lbs).
Fill the transmission with the correct type of fluid (typically Toyota ATF WS) using a fluid pump through the fill tube.

3. Inspect and Replace Transmission Components (if necessary)

Tools Required: Socket set, torque wrench, replacement parts.
If fluid replacement does not resolve the issue, inspect the internal components of the transmission.
Replace any worn components such as the clutch plates or bands if necessary, following the manufacturer's service manual for specific procedures.
