Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery before working on electrical components.

2. Fluid Change

Drain Transmission Fluid
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket set and carefully lower the pan to drain the fluid.
- Dispose of the old fluid according to local regulations.
Replace Transmission Filter (if applicable)
- Remove the old filter and O-ring from the transmission.
- Install a new filter and ensure the O-ring is properly seated.
Install New Transmission Fluid
- Reinstall the transmission pan with a new gasket, ensuring all bolts are torqued to manufacturer specifications (typically 8-10 Nm).
- Use a funnel to add new transmission fluid through the dipstick tube, following the manufacturer's specifications for fluid type and amount (usually around 6-8 quarts).

3. Transmission Control Module (TCM) Reprogramming (if applicable)

Reprogram the TCM
- Connect the OBD-II scanner and navigate to the transmission control module settings.
- Follow the manufacturer's instructions for reprogramming or updating the TCM software.
- Clear any error codes that were previously logged.
