The steps for installing the transmission are as follows: Ensure the torque converter hub is securely engaged in the pump. Raise the transmission into position, keeping it level to prevent the torque converter from sliding out. Connect the transmission fluid cooler lines and align the marks on the torque converter and driveplate. Carefully move the transmission forward until the dowel pins engage with the holes in the bell housing. Install the transmission housing-to-engine bolts and tighten them securely. Install the drive plate-to-torque converter bolts and tighten them to the specified torque. Install the crossmember and remove the jacks supporting the transmission and engine. Install the dipstick tube, starter motor, and reconnect the shift linkage or cable. Plug in the transmission wire harness connectors and install the torque converter cover. If applicable, install the transfer case and driveshaft(s). Install any exhaust system components that were removed and lower the vehicle. Finally, fill the transmission with the specified fluid, run the engine, and check for fluid leaks.

After removing the transmission, it's recommended to inspect the clutch components and consider installing new ones if necessary.

The first step is to disconnect the negative battery cable and remove the shift lever.

Before detaching the transmission, remove the driveshaft and, if applicable, the front driveshaft for 4WD vehicles. If the vehicle has 4WD, remove the transfer case.

Connect the negative battery cable, road-test the vehicle, and check for leaks to ensure a successful transmission installation.

Before removing the drive plate-to-torque converter bolts, mark the torque converter and driveplate for proper reinstallation.
