Solution

1. Preparation

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

2. Fluid Change

Drain Old Fluid:
1. Locate the transmission drain plug and place a drain pan underneath.
2. Remove the drain plug and allow the fluid to completely drain.
Replace Filter:
1. Remove the transmission pan by unscrewing the bolts (use a socket set).
2. Carefully detach the old filter and replace it with a new one. Ensure the new filter is seated properly.
Clean Pan and Magnet:
1. Clean the transmission pan with a suitable solvent and inspect for metal shavings or debris.
2. Remove any old gasket material from the pan and the transmission housing.
Reassemble:
1. Install a new gasket and reattach the transmission pan, tightening bolts to manufacturer specifications (usually around 12-14 ft-lbs).
2. Reinstall the drain plug securely.

3. Refill Fluid

Using a funnel, refill the transmission with the appropriate type and amount of new fluid (check owner's manual for specifications).
Start the engine and let it run for a few minutes, shifting through all gears to ensure fluid circulates properly.
Check the fluid level again and add more if necessary.

4. Test Drive

Reconnect the battery and take the vehicle for a test drive.
Monitor for any signs of shuddering during acceleration.
