Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Change Transmission Fluid and Filter

Drain Old Fluid
- Place a drain pan under the transmission pan.
- Remove the transmission fluid pan bolts using a socket set.
- Carefully lower the pan and allow the old fluid to drain completely.
Replace Filter
- Remove the old transmission filter by unfastening any retaining clips or screws.
- Install the new transmission filter, ensuring it is seated properly.
Clean Pan and Magnet
- Clean the transmission pan thoroughly and inspect the magnet for metal shavings.
- Reinstall the magnet if it was removed.
Reinstall Pan
- Apply a new gasket or sealant to the transmission pan.
- Reattach the pan to the transmission, torquing the bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs).
Refill Transmission Fluid
- Using a funnel, refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual (usually Dexron VI or similar).

3. Inspect and Replace TCM if Necessary

Remove TCM
- Locate the transmission control module, usually found near the transmission.
- Disconnect the wiring harness and unbolt the TCM from its mount.
Install New TCM
- Position the new TCM in place and bolt it down securely.
- Reconnect the wiring harness ensuring a secure fit.
