I've now spent three hours trying to get this bloody thing back on to the truck. Its got four bolts: two to the axle and 2 to the transmission and for the life of me I can't get the thing to line up... its the the tranny is twisted and I can't figure it out.

Ive loosened the engine mount lock bolt, the rear tranny mount and i've been using an air jack under the front diff. to try and get the damn thing to mate up... I am running out of patience today and really need the truck on the road

 

Check for anything like wires that may of fallen between bell and engine.

 

Use two jacks , one under the front axle(mostly on the driverside) and one holding the engine/transmission. Your gonna need to try and wiggle the front axle back and forth and up and down slightly. Thats what worked for me. Also make sure to have to whole front of the truck supported with jackstands while your doing all this

 

Did you ever get it figured out? I'm in the same situation now, and have run out of ideas.
