  A:

  To be able to completely pull out the transaxle, start by taking out the battery and taking out all the fluid from the transaxle. Subsequently, pull out the entire air cleaner assembly inclusive of the PCM for certain models and then, unplug various sensors harness connections, as well as disconnected the transmission fluid cooler hoses and seal their ends. Remove the connections of shift control cable and the steering shaft from the steering gear, and identify the connecting and mating parts for reassembly. Release both power steering hoses and suspend the engine from above with fixture. First, the upper transaxle mounting bolt needs to be unscrewed, the front wheel lug nuts as well as the driveaxle/hub nuts loosened, then the vehicle has to be lifted and supported with jackstands to let the driveaxles be removed and the steering knuckles temporarily reinstalled after that. Disconnect the inspection plate and the torque converter-to-drivplate bolts and nuts, turning the engine for clearance, as well as denote converter's orientation. The next steps by step components to be removed are: transaxle mounting bracket, front and rear lower roll stopper mounts, and front section of the exhaust system will be needed. The engine must be supported and the subframe should be held by floor jacks; the control arms and the stabilizer bar links should be disconnected and the subframe mounting bolts should be removed before lowering the subframe section with help of another person. Position a transmission jack under the transaxle, take out the rest of the transaxle to engine bolts and make sure all the links are disconnected. Push the transaxle back to unload it off the dowel pins, support it with a jack and put locking pliers at the bell housing case to hold the torque converter from falling off. Last of all, can tilt the transaxle backwards and pull it out from beneath the vehicle and safely put it aside. For removal, it is the other way around followed by making sure that the torque converter is fit well with the transaxle fluid pump with the matchmarks on the torque converter and driveplate properly aligned, all the fasteners should be installed before they are tightened and then the transaxle mounting bolts, subframe and the driveaxle/hub nuts and finally the wheel lug nuts should offer a tight fit. Always ensure that the correct type and quantity of ATF for the automatic transmission is used to fill the transaxle and also, the shift cable and the Transmission Range sensor should be set when through.
