Transmission swap! C6 to Zf S5.

TRANS SWAP C6 to ZF

I could use some help and a lot of info on how to swap out my C6 and replace it with the ZF. Is this a straight forward swap or a real big PIA? I use to turn wrenches for a living so there is very little I won't tackle. The truck is an 86 f250 6.9l.

Its a straight bolt in if you have a donor truck to pull parts from. Many have done this swap so hopefully they will chime in with information. I personally have not done the swap. I have done an E4OD trans replacement and will never do another one. The truck must have about 30 inches of clearance so the trans and the trans jack can get under the truck. Most floor jacks lift 17 inches. The engine must be supported too.
