Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to ensure safety while working on the electrical components.

2. Change Transmission Fluid and Filter

Drain the Transmission Fluid
- Place a drain pan under the transmission oil pan.
- Remove the drain plug (if available) or unbolt the oil pan to drain the old fluid.
- Dispose of the old fluid properly.
Replace the Transmission Filter
- Remove the oil pan completely.
- Unscrew the old filter from its mounting position.
- Install the new filter, ensuring it is securely attached.
Clean the Oil Pan
- Scrape off any old gasket material from the oil pan.
- Clean the oil pan thoroughly with a suitable solvent.
Reinstall the Oil Pan
- Apply a fresh gasket or gasket maker to the oil pan mating surface.
- Reattach the oil pan to the transmission, tightening bolts to manufacturer specifications (usually around 8-10 ft-lbs).

3. Refill Transmission Fluid

Add New Transmission Fluid
- Using a funnel, pour the recommended type and quantity of transmission fluid into the dipstick tube (consult the owner's manual for specifications).
- Start the engine and allow it to run for a few minutes, then cycle through the gears to circulate the fluid.
Check Fluid Level
- With the engine running and the transmission in park, check the fluid level using the dipstick.
- Add more fluid as needed to reach the proper level.
