I slide the motor mount bolts through the mount, go under the car and lift the transmission into place with a floor jack, install the transmission mount and bolts, install the drives shaft and tighten the U bolts, lower the rear of the car, and install the nuts on the motor mounts and begin connecting all the lines, wires, hoses, belts, etc. Your method may vary. Works for CJ/C-6. Joe-JDC
