Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Transmission dipstick, funnel
Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, then remove it again to check the fluid level and condition.
If low, add the appropriate type of transmission fluid (usually ATF WS for Toyota).
If the fluid is dark or smells burnt, a fluid change is required.

3. Replace Transmission Fluid

Tools Required: Socket set, drain pan, funnel
Locate the transmission drain plug and remove it using a socket wrench.
Allow the old fluid to drain completely into a pan.
Replace the drain plug and torque it to the manufacturer's specifications.
Refill the transmission with new fluid through the dipstick tube or designated fill port until it reaches the correct level.

4. Inspect and Repair Components

Tools Required: Torque wrench, socket set, screwdrivers
Check the condition of the transmission filter. If it’s clogged, it should be replaced.
Remove the transmission pan by unscrewing the bolts and carefully lowering it.
Replace the transmission filter and gasket, ensuring a proper seal.
Reattach the pan, torque the bolts to the recommended specifications.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and allow it to warm up while checking for leaks.
Perform a test drive to ensure the slipping issue has been resolved.
