I just started building my truck and want to get that junk e4od out of it. Id like to replace with a C6 and hopefully do it myself. I was wondering if that will will be a painless swap(well not really painless), bit if there was something i needed to do to make it work with my engine and transfer case. My truck is a 95 f250 with the 5.8l 351 and taht e4od. I am planning on running 38's at least

 

Out of curiosity why do you call the e4od junk? Is it from rumors that you have heard, or by personal experience? My questions are not to bust your *****, but to gather some info.

1st, your 95 F250 is computer controlled, not only the engine, but the tranny and rear diff as well. By pulling the tranny, you need to change out your ecm to one that came from a manual tranny truck with the same motor, other wise your truck will run like crap! The speed sensor is in the rear diff, not the tranny, so keep that in mind as well.

2nd, If this truck is highway driven much, you will loose your overdrive that the e4od has when you swap in the c6. So if its you DD, and you care the least big with fuel economy, thing otherwise.

3rd, The E4od was not only put behing the 302 and 351w, it also found life behind the big 7.3L diesel! That along with the BW1356 transfer case in the 4wds. So knowing that, I would thing that the e4od should be plenty strong for your 351w, even with 38s. The big problem is the valve bodies suck. Swap in a B&M body, with the Transgo shift kit, and all will be right with the world. I run the e4od and BW1356 combo behind the warmed up 351w in my 95 F-150, and I run it hard off road, even ran it as a full time race truck last year with no issues with either the tranny or transfer case. Oh, and the truck with those parts have 200k miles on them! Check out my gallerys to see the truck I speak of.

Not tryingto put down your idea, I just want to make sure you know what all is involved and that you are making an informed decision, not just that you heard the e4od sucked.

 

The main issue people have with these tranny's is just like any other auto, they overheat them. If you have appropriately sized axle gearing for your tires, and a good cooler/deep sump pan you should have no issues.
If you are dead set on the c6, then go for it. You may have to do some scrounging to find the right tailshaft adapter and whatnot to work with the 1356 case, depending on where you get the c6 from. The main issue will be setting up your tranny kick down linkage. I would think it would be very difficult to set it up with the stock linkage, but I can't see how setting the tranny up with a cable kickdown wouldn't fix that.
Kjett is right about the tranny being computer controlled, but I'm not sure if it would inhibit the running of the truck with out a signal from the tranny. It may throw a check engine code(s), but I think it will still run fine. (Don't quote me on that)

 

The c6 was used at least in 89, as my buddy has one in his Bronco with a manual shift 1356 behind that, so if you find one from that generations, you should be good with no special adapters needed. It works well, just no overdrive.

We tried the c6 swap in another guys truck that still had the stock ecm for 93, and the truck ran like crap, the fuel system was was off due to not having the right input codes from the tranny. Finally ended up getting and ecm from a junked truck that had a manual tranny in it, and it has been running fine ever since. He's since pulled the 351w for a built 351C, so no more fuel injection or ecm to worry about anymore.

 

I have had the tranny in my truck rebuilt twice already and my truck only has 110,000 on it. To me something isnt right. I have never had a tranny even start to slip until after at least 170,000 miles. But after consider your input maybe just getting a new tranny might fix the problem and be an easier solution than going through all that.

Is there anything i can do to make my tranny a little more stout?
Thanks alot for all the input

 

Sounds like the shop doing the rebuilt might have been skimping on some stuff, not sure why you'd have to have it rebuilt twice in that low of milage. Your best solution might be, like you said, to get a "new" transmission. As for things to do to build it up, check out Performance Automatic as they do a lot with the Ford trannys. There are hardend input shafts, panetarys and all sorts of stuff you can do, it all depends on your budjet, and what you are using it for.

Out of curiosity, do you have and tranny cooler, and not just the one built into the radiator? I have the factory auxillary one on my 95 as it came with the "tow package" and like I said earlier, I beat the crap out of this truck, and up until I took it off the road in 06, it was my plow truck.

 

Yeah i do i have actually not been to impressed with the tranny shop i used to have a jeep as my toy and they f-ed me on 2 transfer cases. So thats a really good possibility. I seen you swapped a d44 instead of a d60 what made you decide that?

 

yeah my truck is the xlt 3/4 ton and it ahs about every option they had for that year

 

I wasn't saying you couldn't find one that would work right out of the box, just say that if it came from an older truck it could have a different output shaft length requiring a different tailhousing to work with your case.

 

I know, I was just clarifying for him if he still wanted to go the c6 route, and wanted to give him a place to start looking. We're good!!!

Well, sad to say about your local shop, but if it walks like a duck, and looks like a duck, then guess what it probably is??? As for me swapping a D44 instead of a 60, I wasn't ready to make the transtion to the 1 ton stuff yet, and the 44 is pretty much a bolt in deal with the coils from my previous coiled TTB, so it was a matter of $$. Other than me getting a little silly and welding the front and turning the wheel too far, I haven't had any real problems that weren't self inflicted. I actually got a 10.25 rear that I was planning on swapping in, and I even have the D44hd knuckle/hub/spindle/rotor/caliper that I was going to do while I was at it, but I need funds for the racer, so the rear will go in a deal I already made, and I'll hang on to the front stuff until later on when I feel I need to step up to the 3/4 ton relm.

 

we just talked about this not to long ago, stg said they used c6 right up till 96, i have a c6 factory in my 95 f250 4x4, shouldn't have a run issue swaping to c6 with a 351 usually only run into it when you swap in a truck with a 302 some speed density, mass air crap. idk i personally not big fan of e4od, its a good trans but i don't like the computer controled crap, i don't like fuel inj either but, hey i'm old

 

Oh, believe me I like my carbs too! The problem is if he already had the e4od, with either SD or Mass Air, then his ECM is set to run with that trans, to swap in a C6 from any year, he would need a different ecm for the truck to run and drive like it did with the e4od. Now if he had one of the rare, no OD Auto trannied trucks, then thats a different story! I believe the non-OD tranny was a "special order" deal, and not something found sitting on the typical lot, unless the dealer had a clue about work trucks!

 

mine was special ordered, 351, c6 ,4.10s lim slip, loaded with power and air, i guess its quite rare to find a c6 in a newer truck
