Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Drain pan
- Socket set
- Torque wrench
- Gasket scraper
- Clean rags
Safety Warnings:
- Ensure the vehicle is on a flat surface and secured with jack stands before working underneath.
- Allow the engine to cool before starting.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan and drain the fluid into the pan.
Clean the pan and inspect for metal shavings or debris.

3. Replace Gasket or Seals

Remove the old gasket from the transmission pan and clean the mating surfaces using a gasket scraper and clean rags.
Inspect and replace any worn seals around the transmission.
Apply a thin layer of RTV silicone gasket maker if required for a better seal.

4. Reinstall Transmission Pan

Align the cleaned transmission pan with the new gasket in place.
Hand-tighten the transmission pan bolts, then use a torque wrench to tighten them to the manufacturer's specified torque (usually around 10-12 ft-lbs for the XV40).
Ensure all bolts are tightened evenly to avoid warping the pan.

5. Refill Transmission Fluid

Use a funnel to refill the transmission with new fluid through the dipstick tube, ensuring you use the correct type of transmission fluid (Toyota Type T-IV).
Start the engine and let it warm up while moving the gear selector through all gears to circulate the fluid.

6. Check for Leaks

After refilling, inspect the transmission pan and seals for any signs of leaks.
Allow the vehicle to run for a few minutes and then check the fluid level again, adding more fluid if necessary.
