1977 F 150 4x4 ( bought it new in April 1977 ) ,,, 351 m ,,, manual trans NP435 -- pulled out of the driveway ,, just going to shift into 4th ( in 2 high ) -- Bang -- over to the shoulder we go -- don't know whether the transmission input shaft sheered off or something in the trans/ transfer case let go -- towed back home ------ my question is the need for the tips and tricks to remove the trans without it crushing me in the process ------- any help here is appreciated ,, thanks in advance --- truck has never been abused in its life .
When I removed the T18 from my 1979 F150 4wd, I did what I thought was the conventional method. I chose to remove the transfer case, then unbolt the transmission from the bellhousing. Before I was half way done, I realized that was a mistake. It would have been far easier to remove the engine, then unbolt the transmission from the transfer case, leaving the transfer case attached to it's crossmember and frame bracket.

Similar experience here. I had to replace the clutch disk and transmission input seal on my 1979 F150 4X4 400 T18 so I pulled the engine. It was much easier than trying to deal with the transmission & transfer case. I had the engine out a couple of years earlier so I knew what I was getting into. There are a few other things that are easier to deal with when the engine is out--timing chain, leaking oil pan gasket, ring gear, pilot bearing etc. if necessary. I have never pulled the transmission but having the engine out of the way would definitely be a good start. I have seen some people pull the transmission up through the cab floor with a cherry picker--seat & floor covering were already removed.

Yep, who'da thunk it. And even if the transfer case needs to come out for service, it'd still be easier to pull the transmission out through the front. If you've never pulled the engine out of that truck, don't be intimidated. It's not difficult, and like Mercury said, it affords you the opportunity to do some maintenance on the engine. And if you need to do maintenance on the engine bay, suspension, steering, front axle, etc., it's so much easier with the engine removed. The transfer case is the most difficult of the three to deal with. It's very heavy, very off balance, doesn't sit well on a transmission jack, and you're working on your back (unless you've got a lift). When lining up shafts and seals, I'd rather have to manhandle the transmission than the transfer case. It's much easier to re-install transfer case first, leave the four crossmember bolts and side bracket bolts loose, then install the transmission.
I removed my np435 and 205 together with engine hoist thru cab door and trans tunnel removed, seat removed. Back in i used a transmission jack for dumptrucks.
no pics of coming out but I have seen them on FTE like that is where I got the idea
If your working by yourself, I have run a stout piece of pipe across the back of the bench seat and dash with the gear shift and inspection cover out of the way. I then ran a com-a-long hung off the stout pipe and the tranny secured with chain lowered the tranny safely to the ground. This allowed me to work on freeing it without fear it would fall on top of me.
