Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Check Fluid Level:
- Remove the transmission dipstick, wipe it clean, reinsert, and check the level.
- If low, add the correct type of ATF (Automatic Transmission Fluid) specific to Toyota specifications.
Replace Fluid:
- Drain the old transmission fluid by removing the drain plug (if equipped) or the pan.
- Replace the transmission filter if clogged or contaminated.
- Reattach the drain plug and refill with new ATF using a funnel, ensuring the correct fluid type and amount.

3. Inspect and Replace Transmission Components

Inspect the Transmission Pan:
- Remove the transmission pan bolts and carefully detach the pan.
- Clean the pan and magnet to remove any metal shavings or debris.
Replace the Filter:
- Remove the old filter, ensuring any O-rings are also removed.
- Install the new filter and ensure it is securely in place.

4. Reassemble and Test

Reattach the transmission pan using a new gasket and torque bolts to the manufacturer's specifications.
Reconnect the negative battery terminal.
Start the vehicle and let it idle, then check for leaks.
Perform a test drive to ensure smooth shifting and monitor for any slipping issues.
