Remove the rear transmission mount-to-crossmember nut(s) and the cross member-to-frame bolts.

Proceed to remove the crossmember and transmission mount, and then lower the engine/transmission assembly to detach the fuel line retaining clips.

You should support the engine/transmission assembly with a jack. Then, remove the transmission mount bolts, catalytic converter hanger, and support braces.

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.
