Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Change and Filter Replacement

Tools Required: Socket set, torque wrench, fluid pump.
Sub-steps:
1. Remove the transmission pan using a socket set.
2. Drain the old transmission fluid into a suitable container.
3. Replace the transmission filter according to manufacturer specifications.
4. Reinstall the transmission pan with a new gasket, tightening bolts to the specified torque.
5. Refill the transmission with the recommended fluid type through the dipstick tube.

3. Torque Converter Replacement (if necessary)

Tools Required: Floor jack, jack stands, transmission jack, socket set, torque wrench.
Sub-steps:
1. Raise the vehicle using a floor jack and support with jack stands.
2. Disconnect the driveshaft or axles from the transmission.
3. Remove any electrical connectors and hoses attached to the transmission.
4. Unbolt the transmission from the engine and lower it to access the torque converter.
5. Remove the torque converter from the transmission input shaft.
6. Install the new torque converter by aligning it properly and pushing it onto the input shaft until it seats.
7. Reassemble the transmission, reconnecting all components and ensuring proper torque specifications.
