Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Dipstick, funnel, transmission fluid.
Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and pull it out again to check fluid level.
If low, add the correct type of transmission fluid (typically Toyota ATF WS) as needed.
Inspect the fluid for color and smell; if burnt or contaminated, a fluid change is necessary.

3. Replace Transmission Filter

Tools Required: Socket set, screwdrivers, new transmission filter, gasket, transmission fluid.
Remove the transmission pan by unscrewing the bolts and carefully lowering it.
Remove the old filter by unfastening it from the transmission.
Install the new filter and ensure it is securely in place.
Clean the pan and replace the gasket before reattaching the pan.

4. Refill Transmission Fluid

Pour the appropriate transmission fluid into the dipstick tube using a funnel.
Start the engine and cycle through the gears to help circulate the new fluid.
Check the fluid level again with the dipstick and add more if necessary.

5. Reconnect Battery

Reconnect the battery terminals and ensure they are tight and secure.

6. Test Drive

Take the vehicle for a test drive to monitor the shifting behavior.
Pay attention to any unusual sounds or continuing delays.
