Solution

1. Regular Fluid Checks

Sub-steps:
- Park the vehicle on a level surface and set the parking brake.
- Start the engine and let it idle; shift through all gears to circulate fluid.
- Remove the transmission dipstick, wipe it clean, reinsert, and check the fluid level.
- If low, add the recommended Toyota ATF (Automatic Transmission Fluid) to the fill mark.

Sub-steps:
- Gather necessary tools: socket set, transmission fluid pump, drain pan, and a new transmission filter if applicable.
- Raise the vehicle securely using jack stands.
- Remove the transmission pan bolts and gently lower the pan to drain old fluid into the pan.
- Replace the old filter if equipped; install the new filter, ensuring it’s seated properly.
- Reinstall the transmission pan with new gasket material and torque bolts to specified values (usually around 7-10 ft-lbs).
- Refill the transmission with the appropriate amount of new Toyota ATF through the dipstick tube.

3. Perform a Transmission Flush (if necessary)

Sub-steps:
- Connect a transmission flush machine according to the manufacturer's instructions.
- Run the flush machine, following the procedure to clean out old fluid and contaminants.
- Refill with new Toyota ATF once flushing is complete.
