Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fluid catch pan.
Gather the necessary parts: transmission fluid (Toyota WS type), transmission filter, and gasket.
Ensure the vehicle is on a level surface and the engine is cool.

2. Fluid Change

Sub-steps:
1. Lift the Vehicle: Use a jack and jack stands to safely elevate the vehicle.
2. Remove the Transmission Pan:
  - Place a fluid catch pan under the transmission pan.
  - Remove bolts using a socket set and carefully lower the pan to drain the old fluid.
3. Replace the Filter:
  - Remove the old filter by releasing any retaining clips or screws.
  - Install the new filter securely.
4. Clean the Pan:
  - Clean the transmission pan with a suitable solvent and a lint-free cloth.
  - Remove old gasket material from the mating surface.
5. Install New Gasket:
  - Place a new gasket onto the pan and position the pan back onto the transmission.
  - Torque the bolts to the manufacturer's specifications (typically 6-8 ft-lbs).

3. Refill Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or filler tube.
2. Use a funnel to add the new transmission fluid slowly.
3. Start the engine and allow it to idle.
4. Shift through all gears with the brake applied, then check the fluid level using the dipstick.
5. Add fluid as necessary to reach the proper level.

4. Test Drive

Sub-steps:
1. Take the vehicle for a short test drive to ensure smooth shifting.
2. Monitor for any slipping or unusual noises during the drive.
