Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to avoid electrical issues.

2. Check and Top Off Transmission Fluid

Locate the transmission dipstick (if applicable) or fluid fill plug.
Remove the dipstick or fill plug and wipe clean with a lint-free cloth.
Insert the dipstick back into the tube without screwing it in and pull it out to check fluid level.
If low, add the manufacturer-recommended transmission fluid slowly using a funnel until the correct level is reached.
Recheck the fluid condition; if burnt or contaminated, a fluid change may be necessary.

3. Inspect Transmission Linkage

Locate the transmission linkage connected to the transmission and the gear shifter.
Visually examine the linkage for signs of wear, damage, or disconnection.
If damaged, replace the linkage or cables as necessary.

4. Test and Adjust Clutch (Manual Transmission)

For manual transmissions, check the clutch fluid level; top off if low.
If the clutch pedal feels soft or spongy, bleed the clutch system to remove air.
Adjust the clutch pedal free play according to the manufacturer’s specifications.

5. Inspect Brake Switch (Automatic Transmission)

Locate the brake switch near the brake pedal.
Test the switch for continuity using a multimeter.
If faulty, replace the brake switch to ensure proper shifting functionality.
