Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely elevated if needed.
Disconnect the negative battery terminal.

Tools Required:

Socket set
Torque wrench
Transmission fluid pump
OBD-II scanner
Fluid catch pan

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it.
Check the fluid level; if low, add the recommended transmission fluid (Toyota ATF WS).
If fluid appears burnt or contaminated, proceed to drain and replace it.
- Place a fluid catch pan under the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan and drain the fluid completely.
- Replace the transmission filter if applicable.
- Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (typically around 8-10 ft-lbs).
- Refill the transmission with the appropriate amount of new fluid.

3. Inspect and Repair Transmission Control Module (TCM)

Locate the TCM (usually found near the transmission or under the dashboard).
Check the wiring and connectors for any damage or corrosion.
If any issues are found, repair or replace the damaged components.
If the TCM appears functional, consider resetting the system by disconnecting the battery for a few minutes.

4. Test Drive

Reconnect the negative battery terminal.
Start the vehicle and let it warm up to operating temperature.
Engage the transmission through all gears to ensure smooth operation.
Perform a test drive to check for any remaining slipping issues.
