Solution

1. Preparation

Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, fluid catch pan
Remove the transmission fluid drain plug and allow old fluid to drain completely.
Inspect the old fluid for metal shavings or burnt smell.
Replace with manufacturer-recommended transmission fluid (usually Toyota ATF WS).
Reinstall the drain plug and torque to manufacturer's specifications (typically around 29 ft-lbs).

3. Inspect and Replace Transmission Filter

Tools Required: Socket set, screwdriver, transmission filter kit
Remove the transmission pan by unscrewing the bolts and gently prying it off.
Remove the old transmission filter and replace it with a new one from the filter kit.
Clean the transmission pan's surface and reinstall it with a new gasket.

4. Check Transmission Linkage

Tools Required: Wrench set
Inspect the linkage for any signs of wear or misalignment.
Adjust or replace any worn components to ensure proper shifting.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the engine and check for fluid leaks around the transmission.
Test drive the vehicle under various conditions to confirm that the slipping sensation is resolved.
