Nissan 31020-3CX0D Automatic Transmission Assembly

To dismantle the transaxle of 2011 and earlier models of the vehicle, you will first drain the transaxle fluid, and then extract the engine and the transaxle of the car. Remove the connectors from the component and the braces connecting the harness as well as other braces around the transaxle and starter motor housing. Painter match marks of the torque converter and driveplate before being reunite, and the nuts of torque converter should then be removed. Place the engine hoist under the engine and the floor jack under the transaxle, remove transaxle-to-engine mounting bolts and collect the bolts in a container while arranging the similar bolts together. Disengage the transaxle from the engine and pull it aside and if non-essentials are on the outside then they should be removed and the holes covered to avoid contamination. On models made for 2012 and later, uninstall the battery, batter tray, and air filter housing, then, pull out the transmission control module as well as disconnect numerous sensors and cables. For 6th speed transaxles let the oil cooler lines be disconnected; for the CVT transaxles let the coolant hoses be disconnected. Set the engine to the standard position, remove the torque rod then discard the driveaxles, the starter, the paint match marks besides the torque converter and the driveplate. First, loosen the transaxle mount bracket bolt and the transaxle to engine bolt, then, disconnect the transaxle to engine, then lower the transaxle from the car. When installing keep off new O-rings and copper washers and make sure that the torque converter hub is well locked in the pump and the chromatophore is well aligned with the driveplate. Slowly slid the transaxle forward towards the engaged position and torque the bolts to the prescribe torque values and rotate the engine to check that there is free mobility. Next, add the specified amount of transaxle fluid, add more water coolant if required, and test the transaxle by shifting through all gears. Last but not the least include the road test and look for the signs of fluid leakage.
