Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, transmission fluid dipstick, clean rags, drain pan.
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool down before starting the procedure.

2. Check Fluid Level and Condition

Remove the transmission dipstick and wipe it clean with a rag.
Reinsert the dipstick fully and then remove it again to check the fluid level. If low, proceed to add fluid.
If the fluid is dark or has a burnt smell, it will need to be replaced.

3. Replace Transmission Fluid

Tools Required: Socket set, funnel, transmission fluid (refer to owner’s manual for specifications).
Place a drain pan under the transmission pan and remove the drain plug or the transmission pan bolts (if no drain plug is available).
Allow the old fluid to completely drain out.
Replace the drain plug and torque it to the specifications provided in the service manual.
Refill with new transmission fluid through the dipstick tube using a funnel, ensuring the correct type and quantity are added.

4. Inspect and Replace Filters if Necessary

If the transmission has an internal filter, remove the transmission pan to access it.
Replace the filter according to manufacturer specifications.
Clean the transmission pan and reattach it with new gasket material or sealant if required.

5. Test Drive and Monitor

Start the engine and allow it to idle, checking for any leaks around the transmission.
Shift through all gears with the vehicle stationary, then take the vehicle for a test drive to ensure smooth operation.
Monitor for any burning smells or unusual behavior during the test drive.
