Solution

1. Preparation

Gather tools: socket set, torque wrench, OBD-II scanner, transmission fluid, and a clean rag.
Ensure the vehicle is parked on a level surface and the engine is off before starting.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If fluid is low, add the appropriate type (refer to owner's manual for specifications) and check for signs of contamination.

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage connected to the shifter.
Check for any wear or damage; replace if necessary.
Adjust the linkage to ensure proper alignment and operation as per the manufacturer’s specifications.

4. Inspect Transmission Mounts

Using a socket set, remove the bolts securing the transmission mounts.
Inspect the mounts for cracks, separation, or excessive wear.
Replace any damaged mounts with new ones and torque the bolts to the manufacturer’s specifications.

5. Fluid Change (if necessary)

If the fluid is contaminated or burnt, drain the old fluid using a drain pan.
Replace the transmission filter if applicable.
Refill the transmission with the correct type and amount of fluid per the owner’s manual guidelines.
