Solution

1. Preparation

Gather necessary tools including a socket set, OBD-II scanner, fluid pump, and torque wrench.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check and Replace Transmission Fluid

Step 1: Remove the transmission fluid dipstick and wipe it clean.
Step 2: Insert the dipstick back and check the fluid level; add fluid if low.
Step 3: If the fluid is dark or burnt, drain the old fluid using a fluid pump.
Step 4: Replace with new OEM transmission fluid according to the manufacturer’s specifications (typically Toyota ATF WS).

3. Replace Transmission Filter

Step 1: Remove the transmission pan bolts using a socket wrench.
Step 2: Carefully lower the pan and drain any remaining fluid.
Step 3: Remove the old filter and replace it with a new one, ensuring a proper fit.
Step 4: Clean the pan and replace the gasket before reinstalling the pan.

4. Inspect and Repair Wiring

Step 1: Visually inspect the transmission wiring harness for any frayed or damaged wires.
Step 2: Use a multimeter to check for continuity and proper voltage to the transmission solenoids.
Step 3: Repair or replace any damaged wiring or connectors as needed.

5. Reassemble and Test

Step 1: Reconnect the battery terminal.
Step 2: Start the engine and let it warm up; check for fluid leaks from the transmission pan.
Step 3: Test drive the vehicle to confirm that the slipping issue has been resolved.
