Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before starting work on the transmission.

2. Check and Change Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and wipe it clean.
2. Insert the dipstick back into the tube and remove it again to check the fluid level. It should be within the "Full" range.
3. If fluid is low, add the manufacturer-recommended transmission fluid (Toyota Type T-IV or equivalent).
4. Inspect the fluid condition; it should be bright red and clear. If it appears dark or has a burnt smell, proceed to replace the fluid.

Tools Required:

Transmission fluid pump
Funnel

3. Replace Transmission Filter (if necessary)

Sub-steps:
1. Raise the vehicle using jack stands and remove the protective cover (if applicable).
2. Drain the transmission fluid by removing the drain plug and allowing it to fully drain into a pan.
3. Remove the transmission pan by unscrewing the bolts (torque values may vary, check service manual).
4. Replace the old filter with a new one, ensuring it is seated correctly.
5. Clean the pan and magnet, then reinstall the pan with a new gasket, torque the bolts to the specified value.

Tools Required:

Socket set
Torque wrench
Oil catch pan

4. Refill Transmission Fluid

Sub-steps:
1. Refill the transmission with new fluid using a funnel.
2. Start the engine and let it idle for a few minutes, shifting through all gears.
3. Recheck the fluid level and add more if necessary to reach the full mark.
