2. Remove the dipstick or fill plug and check the fluid level.
3. If fluid is low, add the manufacturer-recommended transmission fluid until it reaches the correct level.
4. If fluid is burnt or contaminated, proceed to drain and refill the transmission fluid.

Tools Required:

Transmission fluid funnel
Fluid pump (if applicable)
Rags for cleanup

3. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage at the transmission and shifter assembly.
2. Inspect for wear, damage, or misalignment.
3. If misaligned, adjust the linkage according to the manufacturer’s specifications.
4. Tighten any loose bolts or fasteners.

Tools Required:

Wrench set
Screwdrivers
