2. Check and Replace Transmission Fluid

Check Fluid Level:
- Start the engine and allow it to warm up.
- With the engine running, pull the dipstick and wipe it clean.
- Reinsert the dipstick and remove it again to check the fluid level.
Replace Fluid if Necessary:
- If fluid is low, add the correct type of ATF (Automatic Transmission Fluid) for the RAV4.
- If fluid is dirty or smells burnt, drain the fluid using a fluid pump, and replace it with fresh fluid.

3. Inspect and Replace Transmission Filter

Remove Transmission Pan:
- Raise the vehicle and support it with jack stands.
- Remove the bolts securing the transmission pan and carefully drop the pan.
Replace Filter:
- Remove the old filter and install the new one.
- Clean the transmission pan and reattach it with a new gasket, torquing the bolts to the manufacturer's specifications.

4. Test and Replace the Throttle Position Sensor (if faulty)

Remove the Throttle Position Sensor:
- Disconnect the electrical connector and remove the screws securing the TPS.
Install New Sensor:
- Place the new TPS in position and secure it. Connect the electrical connector.
