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 avoid any electrical issues during the repair.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back and check the fluid level against the markings.
If low, identify and fix any leaks before refilling with manufacturer-recommended transmission fluid.
If fluid is dirty or burnt, perform a fluid change:
- Drain the old fluid by removing the drain plug or pan.
- Replace the transmission filter and gasket.
- Refill with new transmission fluid, ensuring to use the correct type specified in the owner’s manual.

3. Inspect and Adjust Transmission Linkage

Visually inspect the shift linkage for any loose or damaged components.
If necessary, adjust the linkage according to factory specifications, ensuring that all connections are secure.

4. Road Test and Monitor

Reconnect the battery and start the vehicle.
Conduct a road test to ensure the transmission shifts smoothly and no slipping occurs.
Monitor the transmission fluid level after the test and check for any leaks.
