Idi restoration project

I've been plugging away at this thing for a while, I've been doing some thinking though. Some how I wound up with an 89 that still had the c6 transmission in it. If I want to drive this thing around I think while I'm restoring I should upgrade to an e4od, in other words I'm asking how hard it would be as far as electronics and what can I expect to gain as far as Mpgs and drivability? The c6 in it now would have to be rebuilt anyways, just looking for some advice

I would drop a ZF5 in it and go that route, better mileage, reliability and it will pull better.

It's not that hard with an aftermarket controller I've done it, It gained me 4mpg then I finely got it tuned right and I was up to 20mpg

A nice ZF would run you $900 around here. But you'd also have to buy everything to make the truck a manual

ether way I would plan on $2,000 to do, that's if you can find a good used trans for under a grand,
Auto would need, a new converter $300, after market controller $700, different drive shafts, and throttle position sensor. of course the Trans.


Manuel might be cheaper because you don't need a controller, but you would need a clutch and flywheel, drivelines. peddle box, it all depends how lucky you can get at a junkyard.

Incorrect, for every model year with same equipment, an E4OD is rated to out-tow a ZF. My van is rated to tow more than my F350, but the ZF would live longer than the OD in stock form (do a couple of upgrads and have no worries and smooth shifting goodness)

That said, best bang for the buck would be to pick up a cheap donor vehicle that has all the parts you need. Look for one thats wrecked or blown motor and go to town

Virtually no RPM drop between shifting. But, a manual is more fun to drive!
I'd take a 5-speed over an auto anyday

No argument there, my F350 has the ZF and its no problem to drive especially when loaded (actually a lot better with at least 1500lbs in the back)

The van is no slouch either with the E4OD, not brake neck speed, but enough to get you into traffic. Both geared with 4.11s
