idi tranny question
Good afternoon dieselers,
Doing research on a potential idi swap into my 92 bronco. It has been reccomended to go with the 5.9 cummins, because the bell housing is the same and the motor weighs less than the idi. Well the motor doesn't weigh that much less, and I'd rather have the idi. So....it is my understanding that some diesels came with the e40d electronic tranny. This is what I have as well. Does anyone know for sure if an idi will mount to my tranny?

Why not? As I understand it, the bellhousing is non adjustable. So to me it would seem that it is the same transmission behind both the idi and the small block gassers. Trying to get my research done.
Also.....If the idi came in front of the e40d, how did the trans know when to shift since it uses electronic shifting?

On the E4OD the bellhousing is part of the trans casing so the whole thing is manufactured for each engine family. The diesels are a bellhousing bolt pattern all on their own.
As for the shifting the IDI diesel E4OD had a computer in the truck and there is a throttle position sensor on the injector pump. The tach and speedo also supply input to the trans computer.

The diesel bell housing and 460 bell housing are close but will not interchange. There are some that will say they are the same, they are NOT the same.
Ford makes me confused with all the different bolt patterns on their trannys anyway. Never could figure out the why on that idea!!

Another thing the cummins will not bolt up to any ford tranny without an adapter.
The idi will not bolt up to any gas bellhousing but can be installed in your bronco without fabbing parts like the cummins.

The E4OD is actually a nice trans, but you have to maintain it properly and give it a BIG cooler if you want it to last when you use it hard... which is really the case with any automatic transmission.

It also has the widest overdrive ratio compared to other options like a ZF or auxiliary overdrive.

kinda old fashion nowadays joe.
E40D is a great trans.
toss in a shift kit and cooler,and work her hard.i am.
she's getting fluid flushes every 30k miles on the money.
4x4 with OD unlike the GV provides.that would never fly for me.
i like the great fuel mileage year round.20+ avg.right in the engines torque band.
im happy as a clam with my setup for hauling. minus the SRW/non Super Duty springs.but that's getting fixed soon enough.
nothing wrong with built C6 with OD Joe.don't let the "electronic" part scare you.

nothing lasts forever.especially when your working or playing 'em hard.
and certainly not clutches/throw out bearings etc.etc. been down that road enough lol.with light duty f150 mazda tho.i know i cant can't compare that weak stuff to the zf5.but its still PITA messing with pressure plates/clutches,and just shifting in general got old for me.
i used to have an 85 with what we always called a "4 speed creeper" due to its real low 1st gear in the f150.what trans was that?
basically a 3 speed for the street,as ya never used 1st.
i liked that one much better than mazda 5 in the 96.
(still sucked messing with the trans stuff when it broke tho lol.)

Whats old fashioned about the undeniably toughest there is and the gear vendor worhs great in a 4x4, at least it does in mine. Better than a zf5 or a E40D I have wat more gears to play with. And even using them hard the clutches will lasy as long as most trannies. You usually will have to replace the hydraulics though.
