Swapping in a e4od

[InsanePyro]

Sorry for not searching but I'm looking at an e4od on craigslist right now and would like answers so I can decide weather or not to pounce on it.

Looking at a e4od on craigslist for $200 out of a '94 f250. Would this bolt right on? What else would I need from the f250? I'd assume at least the steering column for the button to engage the OD. Anything else?

[SomeDude451]

If it's a small block F250, yes, it will physically bolt up. However, don't expect it do anything unless you get the wiring, and the computer, and the column and rewire a bunch of mess and add sensors and what not. The E4OD is electronically controlled, and nothing else until the later AODE was. So, unless you've got an E4OD in there now, it's going to be a pain in the ass.

What transmission do you have currently?

[B-man]

More information on your rig would help out a little.. What tranny is in there now? Engine size?

I am assuming you have a C-6 3-speed tranny in your rig now? 5.8 liter or 5.0?

Also, like Somedude stated. You jump on that tranny, get every piece of wiring, if not all of the engine bay wiring and the wiring that leads all the way down to the MPLS on the E4OD. Also, get the linkage for the E4OD.

Basically get everything that is involved with the E4OD. ECM, wiring. linkage.

And, research, research, research.

Wow first time ive seen someone wanting to put one in, in a long time. "Is the juice worth the squeeze" ? Its alot of hair pulling if your only going for OD.

[bossind]

I wouldn't buy anything less than a 96 E4od as it has all the upgrades and is as good as they get. Might as well do mass air while your at it.

[InsanePyro]

Yeah I got the C6 with a 351...should I just keep an eye out for a AOD then? Really the only reason I want the tranny is for the better MPG I'm assuming I'd get with OD

[theramsey3]

Go 96 5.8 ecu interior exterior harnesses dash door panels psom whole 9 yards if you are trying to spend money to save money. You would probably enjoy it. But if you do you will need all of the heater controlls and have to do some wiringg harness grafting as well. But if you just want overdrive get either an AOD or a ZF 5 speed manual( it has the same 1-4 ratios as the T18 granny 4 as it is commonly called but has a IIRC .78:1 overdrive gear) but if you want the electronic controlled OD transmission there are many benifits to going to the 96 stuff such as OBDII, tuneability with a handheld/vehicle mounted programmer, updated interior look, PSOM (programmable speed output module/speedometer) so you can make your speedometer accurate to tire size, mass air flow(more horsepower better gas mileage) there are oprions how much do you want to spend and how much work do you want to put into it?

[InsanePyro]

AOD sounds like the way to go...I don't have the time or money to mess around with all that electronics crap...I knew it'd be a undertaking but not that much

[B-man]

I would go as convenient and as simple as possible and what your wallet will let you.

I don't know or didn't know if an AOD would mate up to a 351w. Someone else should know.

If you did go E40D, JUST that. It's not that crazy. It's all the other stuff that gets fun. lol. The MAF stuff and all that. Only the E40D would require the ECM from the rig you are getting the tranny from and some repinning of the ECM. Not hard to do, and the electrical harness in engine bay and wiring down to the E4OD.

But, if an AOD would mount up to the 351w?

That's what I would do.

I have learned that the KISS theory works well.

[4NIC8R]

The AOD should not have any issues mounting up. As for the F250 you saw, the column shifter will be completely different in your truck. If all you're going for is the OD, then an AOD is the way to go.

Personally i would do the zf5 swap.

BTDT and did it cheap with a $800 parts truck and set of synchro-rings.
But that was ~$900 for -2wd- tho. :/

---------------------

It was fun as anything tearing out wiring for the E4od and BW1356-E
etc and taking out that stinkin' broken tilt steering column too! LOL :)

"i don't need this and I don't need that... " LOL :)

Wouldn't be all that much fun putting it back together. :/

I have absolutely no interest in a manual transmission

Thanks for all the quick info guys...time to do some AOD hunting

I have one question though...with an AOD...what gear would I tow with then? Because I don't think I've ever seen a Bronco with a 1 2 D OD cluster

[4NIC8R]

You need a different gear indicator is all.

Look Here

Part number 8, the one listed for an AOD.

[4NIC8R]

Iirc, the AOD indicator says

P R N (D) D 2 1

You won't need a different shifter for the E4OD. In 89-91 the on/off overdrive switch is a seperate button located beside the electronic transfer case buttons if so equipped. It takes the place of the "cubby" hole storage compartment.

As stated by others you would need wiring harness, computer and transmision. The linkage from transfer case to transmission is different between E4OD and C6. There is a difference in transmission shifter linkages between 89-91 shifters and 92-96 shifters too.

I installed an E4OD into my 90 when I swapped in a 351. My truck was originally equipped with a 5.0/AOD combination. I built a 351/E4OD from a 96 F150 to install.

I found a 91 F250 and swapped wiring harness (all of it as the engine/transmission part isn't seperate) and used an appropriate computer. However you can keep your current computer and get a seperate transmission controller from Bauman (and others) that should come with all the necessary wiring changes and instructions. I thought of this route but decided I wanted it as close to factory as I could get. (Not saying this is better or worse, just what I wanted)

There are also differences between the later years and early solenoid packs. The transmission doesn't care but the engine/trans computer MAY not be happy if the wrong combination is used.

The AOD can be built to be plenty strong. I ultimately decided that the E4OD was a better fit for trucks and possible towing, etc. My other reasooning was that Ford never put the AOD behind a 351 in a truck application. (You can get the correct flexplate over the counter by purchasing one from a Crown Vic with a 351/AOD from around 1989.)

Some will tell you, (surprised it hasn't came up already) the E4OD will not function correctly in your vehicle without a PSOM or the VSS in the rear axle. Neither of these is true as Ford equipped 89-91 with this transmission. The VSS in an 89-91 is located in the tailshaft of the transfer case and will allow the transmission to shift just fine. The "VSS" in the factory 8.8 rear end in 89-91 (actually 87-91) was only used for RABS.

Ultimately it is your money, spend it how you want. Hope this helps you make an informed decision on how.

Yup defiantly going with the AOD. Way less stress

He has listed in his profile an 89 Bronco. He said he has a line on a 94 F250. The interior and colums are not the same and the column shifters are not interchangeable.

The shifter istself is still the same. Meaning the shifter in his 89 now will work. (The gear lever on the column and the column) The linkages are different. I covered that in my statement about the 89-91 and 92-96 linkage differences.

The AOD, C6, E4OD all share the same column and shifter. The gear indicator can be changed or not. The transmission will not know the difference.
