Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical issues.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Insert the dipstick back into the tube and remove it again to check the fluid level.
3. If the fluid is low, add the appropriate ATF (Toyota Type T-IV) until the correct level is reached.
4. If the fluid is dirty or burnt-smelling, drain the old fluid using a fluid pump and replace it with new fluid.

Tools Required:

Transmission fluid pump
Funnel

3. Inspect and Repair Transmission Linkage

Sub-steps:
1. Locate the transmission linkage and ensure it is properly connected to the transmission.
2. Adjust the linkage if misaligned and ensure all bolts are tightened to the manufacturer's specifications.
