Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, funnel, clean rags.
Safety Warning: Ensure the vehicle is on a level surface and the engine is off before checking fluid levels.

2. Check and Replace Transmission Fluid

Check Fluid Level:
- Start the engine and let it idle.
- With the transmission in 'Park', pull the dipstick out, clean it with a rag, and reinsert it fully.
- Remove it again and check the fluid level. If low, add recommended transmission fluid.
Change Transmission Fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission drain plug (if equipped) or unbolt the pan to drain old fluid.
- Replace the drain plug or clean the pan and reattach it.
- Refill the transmission with the recommended fluid through the dipstick tube using a funnel.

3. Replace Transmission Filter

Remove Transmission Pan:
- Safely lift the vehicle using jack stands.
- Unbolt the transmission pan and remove it carefully to avoid damaging the gasket.
Replace Filter:
- Remove the old transmission filter.
- Install the new filter ensuring it is seated correctly.
Reassemble:
- Clean the transmission pan and replace the gasket if necessary.
- Reattach the transmission pan and torque the bolts to manufacturer specifications (typically around 10-12 ft-lbs).

4. Test Transmission Operation

Start Engine:
- After reassembly, start the engine and let it warm up.
- Cycle through the gears while stationary to ensure smooth operation.
