I got a 1990 150 supercab 4x4 short box
Got it in a transmission shop getting the aod rebuilt with upgrades
The truck has a manual floor boot but a Borg Warner 1356 e-shift case in it without the shift motor and wiring meaning it's a crawl underneath the truck with vise grips to shift into and out of 4x
What t Case's can I bolt on without changing alotta stuff?
Im a fan of NP. 208 but not sure if they will bolt on an aod
Then there is bw1345 is there much difference between the bw1356 ? Or just find a manual shifting bw1356 and let it be that
Or am I missing another t-case option ?
I do got a few days yet but shop figures the transmission should be ready Wed. It being Thurs. I got till Tuesday to get one there or the old pliers shift case goes in

 

I am not sure about the np's bolting to an ado, I have a c6 that had an 205 on it and they had to modify ( hack up) the tail shaft housing to clear the 205. I'd just get a manual 1356, should be plentiful.

 

Supposedly all aluminum and magnesium transfer cases used on any Ford are interchangeable as far as the transmission is concerned. So any transfer case out of any Ford truck (after the cast iron NP203 and NP205s from the '70s) should be a bolt-on.

Somewhere around '90 Ford moved the speedo pickup from the tailshaft of the transfer case to the rear axle. I don't know exactly what year that was, but if yours has the pickup on the transfer case you might want to go with an earlier 'case to keep that simple (if yours is on the rear axle then any 'case will work).

And newer trucks have a slip yoke at the rear of the transfer case while older trucks (and all Broncos) have a fixed yoke. I don't know when that changeover was either, but if you switch from one to the other you're going to end up needing a new driveshaft.

 

The bw1356 or 1345 is plenty strong for whatever you're doing with an AOD, an added benefit is that they can be found basically anywhere for well under $100.

 

My truck got the slip yoke 1356 so I looked around here in Alberta did some other research and a call to my lord of Ford guru and got the same answers yes you should be able to switch between different t-cases but drive shaft/s and linkages may need to be swapped out depending on the case
I called chop shops and used bw1356 there are 2 on the data base in Alberta one for $550 the other 600 but would need to be shipped with charges a call to the back water shop $450
But the kid that was gonna sell me a bw1356 flanged yoke was gonna throw in a driveshaft but I did shy away just in case suspension compression was too long even by an inch would run risk in my freshly rebuilt aod ($3000) so I turned down the offer
An hr later got a text back from the kid and he found a slip yoke 1356 in he's shed $150 looks good seems to shift good so its in the focus now ready to be dropped off at transmission shop Monday morning

If anybody else is considering this type of swap a measuring tape is your best friend consider suspension cycle and linkages may need a custom touch
Thanks for all your input guys hope this helps out somebody down the road

 

Unless you're on a really tight budget, driveshaft length isn't a big deal. If the ends are right and everything's in good condition it costs under $150 to shorten a driveshaft and not much more than that to lengthen it. I've had both done a few times on my Bronco as I've put different transmissions and transfer cases in it.
