If fluid is low or burnt:
- Drain the transmission fluid using a pan under the transmission.
- Replace the fluid filter if applicable.
- Refill with manufacturer-recommended transmission fluid to the appropriate level.

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage: Inspect for wear or misalignment.
Adjust the linkage: Loosen the adjustment nut, position the linkage correctly, and tighten the nut to manufacturer specifications.
