Solution

1. Preparation

Tools Required:
- Jack and jack stands or ramps
- Drain pan
- Wrench set
- Torque wrench
- New transmission fluid (specific to Toyota specifications)
Raise the vehicle securely with jack stands or ramps.
Allow the transmission to cool if it has been running recently.

2. Drain Old Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using the appropriate wrench.
Allow the old transmission fluid to drain completely into the pan.

3. Inspect and Replace Gasket/Seals

Carefully remove the transmission pan and inspect the old gasket for wear or damage.
If the gasket is damaged, clean the mating surfaces on the pan and the transmission case thoroughly.
Replace the old gasket with a new one, ensuring proper alignment.
Check the transmission filter (if applicable) and replace it as needed.

4. Reinstall Transmission Pan

Position the transmission pan back onto the transmission case.
Hand-tighten the pan bolts in a criss-cross pattern to ensure even pressure.
Use a torque wrench to tighten the bolts to the manufacturer’s specified torque value (typically around 10-12 ft-lbs for most applications).

5. Refill Transmission Fluid

Locate the transmission fluid fill port.
Pour the correct type of transmission fluid into the fill port using a funnel.
Start the engine and let it idle, then check the fluid level with the dipstick (if applicable).
Add fluid as necessary to reach the appropriate level.
