Follow the manufacturer's instructions for transmission removal procedures.
Front wheel drive procedures vary. Make sure to support the engine from the top.

Sometimes, engine cradles, suspension parts, or complete engine/transmissions assemblies must be removed. If axles are removed, fluid drains from the transaxle. Save the fluid in a clean can for refilling later. If the container is not completely clean or is not kept covered, the fluid must be replaced to prevent contamination. When reinstalling the transmission, try to put the transmission back in the same position it was in before. Make sure that the constant-velocity (CV) joint boots are not torn.
Rear wheel drive procedures are more straight forward. These general instructions apply to all transmissions.
- Remove the inspection cover or starter motor to gain access to the engine side of the flexplate.
- Mark the converter and flexplate so they can be reassembled in the same position.
- Unbolt the torque converter from the flexplate and push the converter all the way into the transmission pump.
- Install a transmission jack under the transmission.
- Remove any crossmembers or braces supporting the engine.
- Mark and remove any linkage.
- Remove the speedometer cable or wire.
- Unbolt the transmission from the engine.
- Check to see that any dowel pins that align the engine to the transmission are in place.

- After the transmission is removed, measure the depth of the converter. Make sure the converter is installed to this depth before reassembly. Otherwise, the front pump, torque converter, or transmission case can be damaged during reassembly.

- When reinstalling the transmission, be sure the converter is all the way into the pump.
- Install the transmission and bolt it to the engine.
- Make sure that the engine and transmission are touching each other completely before installing any bolts.
- If the converter is installed properly in the pump, there will be enough room to rotate it to align it with the bolt holes in the flexplate.
- Then, slide it forward and bolt the converter to the flexplate.
When installing the torque converter to the flexplate, be sure to use the correct bolts. Bolts that are too long can be forced through the converter housing or they can leave the flexplate loose. This can result in elongated holes and a cracked flexplate due to excessive vibration. The result is a clunk when shifting from neutral into gear. Bolts too long can also deform the converter housing and lock up the converter clutch.
