2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick; remove it and wipe it clean.
2. Insert the dipstick back and check the fluid level; add fluid if low.
3. If fluid is dirty or smells burnt, drain the old fluid using a fluid pump.
4. Replace with the manufacturer-recommended transmission fluid (consult the owner’s manual for specifications).
5. Recheck fluid level after refilling and ensure it is within the acceptable range.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan using a socket set, being cautious of any fluid spillage.
2. Remove the old transmission filter and discard it.
3. Install the new transmission filter; ensure it is seated properly.
4. Clean the transmission pan and replace the gasket if necessary.
5. Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications.

4. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Visually inspect the transmission linkage for any signs of damage or misalignment.
2. Adjust the linkage as necessary to ensure proper engagement of gears.
3. Lubricate any pivot points to allow smooth operation.

5. Reconnect Battery and Final Checks

Reconnect the battery and start the engine.
Allow the vehicle to warm up and check for any leaks around the transmission area.
Test drive the vehicle again to ensure smooth shifting.
