- Torque wrench
- Fluid catch pan
Safety Warnings:
- Ensure the vehicle is on a level surface and securely supported to prevent movement.

2. Check and Replace Transmission Fluid

Locate the Transmission Dipstick: Open the hood and find the transmission dipstick.
Remove Dipstick: Pull out the dipstick and wipe it clean with a lint-free cloth.
Check Fluid Level: Reinsert the dipstick and remove it again to check the fluid level; it should be within the marked range.
Inspect Fluid Condition: Look for burnt smell or dark coloration; if fluid is contaminated, it needs replacement.
Drain Old Fluid: Use a socket set to remove the transmission pan bolts; carefully drain the old fluid into a catch pan.
Replace Filter (if applicable): Remove the old transmission filter and replace it with a new one, ensuring proper alignment.
Reinstall the Pan: Clean the pan and reinstall it with a new gasket, tightening bolts to manufacturer specifications.

3. Adjust or Replace Transmission Components

Inspect Shift Cable: Check the shift cable for proper adjustment; if misaligned, adjust or replace as necessary.
Examine Clutch Packs: If applicable, check clutch packs for wear or damage and replace if needed.
Check Solenoids: Test transmission solenoids using a multimeter; replace any faulty solenoids to restore proper shifting function.
