2. Insert the dipstick back into the tube and remove it again to check fluid level.
3. If low, add the appropriate type of transmission fluid (consult owner’s manual for specifications).
4. If the fluid is dark or has a burnt smell, plan to change the fluid completely.
Tools Required: Transmission fluid pump, funnel, clean rags.

3. Inspect and Replace the Transmission Filter

Sub-steps:
1. Raise the vehicle using jack stands for access.
2. Remove the transmission pan bolts using a socket set.
3. Carefully lower the pan and drain the fluid into a container.
4. Remove the old transmission filter and install the new one.
5. Clean the transmission pan and replace the gasket before reassembling.
Tools Required: Socket set, torque wrench, gasket scraper.

4. Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage assembly.
2. Check for any misalignment and adjust the linkage to ensure proper engagement.
3. Test the movement of the linkage to confirm smooth operation.
Tools Required: Wrench set, pliers.

5. Replace Transmission Mounts (if needed)

Sub-steps:
1. Remove the bolts securing the old transmission mounts.
2. Lift the transmission slightly using a jack for clearance.
3. Install the new mounts and secure them with bolts to the specified torque.
Tools Required: Jack, socket set, torque wrench.
