Borg Warner 1356 Electric Shift on the Fly

When I did my 4X4 conversion I decided that I wanted an electric shift on the fly transfer case for several reasons, but mostly because I didn't want a shift lever in the middle of the floor.

Most 4-wheeling that I do in the SMB is in high range and at faster speeds than low range can be driven at. I hardly consider my EB a hard core wheeler - I have a Jeep and other full size 4X4's for that, but we love to get out to the deserts and beaches of Baja and CA.

I picked a Borg Warner 1356 with electric shift from a Bronco or F150 because I have had good success with them in the past, even in racing applications.

To get the electric shift on the fly to work, I picked up the complete wiring harness, computer, and shift button assembly from a donor '95 F150. I located the computer under the steering column, behind the steel knee guard panel. It requires power and ground, key switched power, connection to the neutral safety switch, brake switch, dash light dimmer and to the Speed Sensor on the back of the transfer case.

I mounted the selector buttons in the panel to the right of the steering column. It all works great, just as it did in the Bronco/F150 i took it from and I am very happy with it.

Re: Borg Warner 1356 Electric Shift on the Fly

Congratulations! I wanted that done when I had my van converted to 4x4, but the converter talked me out of it.

Any chance you could describe the model, engine and year of your van and post some pictures?

I would like to remove my manual BW 1356 and replace with a esof NV 273 transfer case.

'97 E350 EB V10.

I'll try to get a picture of the Button - everything else is tucked away.

Re: Borg Warner 1356 Electric Shift on the Fly

FWIW - QuadVan also does ESOF but using the NV273. In the pre-'09 vans the dial replaces the cig lighter, and in the newer vans it goes on the flat panel between the steering column and the radio.

Normally I like to keep things simple. But with a van, especially with backseat passengers, I'd rather not have a shifter on the floor between the seats.

Re: Borg Warner 1356 Electric Shift on the Fly

I have had shift on the fly and auto hubs fail me. Expensive to replace.
Hard core manual is the way for me, especially on a 1 ton. Never mind the inconveniences.
Good luck with it.

Re: Borg Warner 1356 Electric Shift on the Fly

I keep bumping the transfer case lever when I climb from the back into the drivers seat.

I've been considering everything from moving the lever to the other side of the drivers seat (might be a bit too much linkage), adding some sort of a gate, or replacing it with a multi position solenoid. I don't think I'll go as far as swapping an otherwise serviceable transfer case, but if I was starting from scratch, I'd consider one with electric shift.

There's no reason you couldn't use manual (or even semi manual) hubs with it, which is really the thing that fails in the fully automatic setups.

Auto hubs can be problematic, especially if not serviced regularly, I'm not using them - they are standard locking hubs. If the transfer case does to not want to shift with a push of the button, it is relatively easy to shift it manually and anything that could fail is pretty cheap new or real cheap from the wrecking yard.

Keeping the shifter off the floor is well worth the outside chance and temporary inconvenience of it failing at some point and being easily remedied afield.

But, I understand your concerns - that is why when I ordered my SuperDuty, I ordered it with a manual transfer case and manual hubs, the vacuum operated hubs on them are particularly problematic. Luckily they are manually operable as well.
