Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool if it has been running.

2. Drain and Replace Transmission Fluid

Drain Fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan to allow fluid to drain completely.
Replace Filter (if applicable):
- Remove the old transmission filter.
- Install the new filter, ensuring it is seated properly.
Clean Pan:
- Clean the transmission pan thoroughly with a solvent to remove any old gasket material and debris.
Reinstall Pan:
- Install a new gasket on the transmission pan.
- Reattach the pan to the transmission and torque the bolts to the manufacturer’s specification (usually around 8-12 ft-lbs).

3. Refill Transmission Fluid

Add New Fluid:
- Using a funnel, refill the transmission with new, manufacturer-recommended transmission fluid through the dipstick tube.
- Refer to the owner's manual for the exact type and amount of fluid (typically around 8-12 quarts, depending on service type).
Check Level:
- Start the engine and allow it to run for a few minutes.
- Cycle through all gears and return to park.
- Recheck the fluid level and add more fluid if necessary.
