Install New Fluid:
- Clean the transmission pan and reattach it with a new gasket.
- Refill the transmission with the manufacturer-recommended fluid using a funnel.
- Start the engine and allow it to reach operating temperature while checking fluid levels.

3. Inspect and Reprogram TCM

Access TCM:
- Locate the TCM, usually found near the transmission or under the dashboard.
- Disconnect the battery (negative terminal) before working on electrical components.
Reprogram TCM:
- Use a compatible diagnostic tool to access the TCM settings.
- Follow the manufacturer's instructions to reprogram or update the TCM software.
Reconnect Battery:
