2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check fluid level.
2. If low, add the appropriate type of Toyota transmission fluid (typically ATF WS).
3. If fluid is burnt or discolored, drain the transmission fluid using a catch pan.
4. Replace the fluid by using a transmission fluid pump to add new fluid through the dipstick tube.
5. Recheck fluid level after running the engine and cycling through the gears.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan bolts using a socket set.
2. Carefully drop the pan and allow any remaining fluid to drain.
3. Remove the old transmission filter and replace it with a new one.
4. Clean the transmission pan and magnet, removing any debris.
5. Reattach the pan with a new gasket, tightening to the manufacturer’s torque specification.

4. Check and Adjust Linkage

Sub-steps:
1. Inspect the shifter linkage for any signs of wear or misalignment.
2. If misaligned, adjust the linkage according to service manual specifications.
3. Tighten any loose bolts or nuts that may affect shifting.

5. Replace Transmission Range Sensor (if necessary)

Sub-steps:
1. Locate the transmission range sensor, usually mounted on the side of the transmission.
