Motor Swapping a 4x4 86 ranger

So I've been having issues with my ranger its a 86 with the 2.9l v6 and automatic 4x4 transmission been having issues with both motor and trans and ive been thinking of swapping it and a buddy sent me ads for a 86 302 and also a 89 AOD 4x4 trans now what would need to be done for that to fit? The 302 is carbureted while the 2.9 is fuel injected. Now I've got the full set up with the 2.9 automatic everything except windows auto locking hubs press button 4x4 and auto trans i want to keep that so im trying to figure out what I should be looking for

Welcome to the forum

The carb'ed 302 with an AOD trans is a good combination, but your BW1350 transfer case won't bolt to the 4x4 AOD, and it would fail pretty quick in any case

You will need a BW1356 with electric shift, your current shift motor and controller will work with this transfer case, and auto hubs, they don't care about any of this

The BW1356 is wider than the 1354, so when you mount the engine and trans move them 3/8" to passenger side, and it will fit, or you can notch the frame but that will weaken it unless you reinforce it

On the AOD there is a cable adjustment that is VERY important, you will burn up the trans unless its done right

the AOD has its own transfer case already will that work?

Yes, if it's electric shift, 1989 should be BW1354

Rear will look like this: https://www.smartpartsauto.com/image...nsfer_case.jpg

You can see where your shift motor would go, exactly the same setup as on the BW1354, or if it has a shift motor on it, you can use it, same wiring harness

Your rear drive shaft, of course, won't work, wrong length, not sure about the front drive shaft

"...also a 89 AOD 4x4 trans......"

1986 AOD with transfer case may be the BW1345 which was manual shift only, it was used 1980-1988 on F-series

This is a BW-1356 correct? It looks like it has a elctronic shift,


I just want to make sure its gonna work because my ranger is my daily driver and I can't decommission it for too long I know both driveshafts will need to be changed

Its a BW1356 alright but a manual shift
All BW1356 have rear case thats cast with electric shift but its sealed and bolt holes are not drilled or threaded, if its going to be a manual shift

The shift shaft with bar attached is on front case, the electrical plug-in just below it is for High Low 4WD lights on the dash

Short video of a BW1356 manual shift here:


Electric shift BW1356 rear housing would look like this: https://i.ytimg.com/vi/CXDWLXnW_sQ/hqdefault.jpg

Yes, it would just plug in to your harness, you Ranger shift motor would also work on it

Manual shifts are more popular with 4-wheelers so you shouldn't have a hard time finding a Swap
Go Bronco or full size Ford truck forums and post that you want to trade

thank you, now it was mentioned above shifting everything 3/8ths of an inch towards the passenger side so I wouldn't have to notch the frame do you happen to have any pictures or videos of this being done?

Have a look at this article: https://www.therangerstation.com/Mag...7_ranger.shtml

You can see how the V8 mounts using Ranger mounts and V8 plates, so you can elongate the holes in the plates and add holes for locator pins vs grinding then off

This guy is using the Explorer AWD transfer case so no clearance issue except for remote oil filter which needs the same shifting to passenger side
Same for transmission mount, elongate the holes, either at the trans or at the cross member ends
