1990 E4OD to 5spd swap???
Well, as the title states, I am curious about any problems that may arise if trying to do a E4OD to 5spd swap.
My thoughts--> With 97k miles, I seriously doubt the E4OD will go too many more miles before having to be rebuilt. Given the high price of a quality rebuilt E4OD and the fact that a 5spd would still likely be more durable, I have considered doing a swap when the E4OD kicks the bucket. I like a manual transimisson anyways and I was thinking that I could probably find a wrecked 5spd truck for around $500. With the entire wrecked truck on hand, I would have everything I need (pedals, shifter, boot, flywheel, etc...). This would definetly be a very involved project and something beyond my previous experience, but in theory it looks like it would work out.
Reason for posting-->
1. Issues that I may not have thought of?
2. average 5spd life in miles?
3. What 5spd trucks would be compadible? Any 3/4-1ton? 460 trucks only? Any Fseries truck?
4. Will I need to swap the computer too?
5. If I could find a newer 460 truck, could I convert my truck to a MAF system/computer as an added bonus?
Thanks in advance for information

Well, I just ran across this thread and it has given me a few things to think about. Cant believe I didnt see it before starting a new thread.
https://www.ford-trucks.com/forums/5...-match-up.html
With the balance issue, I could have the flywheel match balanced to my current flexplate right? Problem solved.
As mentioned in the above thread, I would be looking for better economy too. My current best MPG on highway only is 14.5 and mixed/city around 10.
Will my 3:55s be too high for the 5spd? Should be great for the highway, but I assume a little sluggish when pulling the 5th wheel.

Well the first thing in that thread he was looking to swap a 5 spd into an older truck with an unknown year engine so the balance could have been an issue, but any F250 or F350 with a 5spd will have the same balance as your engine so the flywheel shouldn't be a problem.
compatiblily is the F250 or F350 with a 460 because thats the only ones that will hve the right flywheel and bellhousing that you need, and I believe that you need to swap the computors also because the E4OD is controlled by it, and when it doesn't see the trans it's going to throw a code. (Your current computor that is), but that means you need to have the right engine managment system for that ECM so if it's maf thats what your going to have to run.
Average life? Heck I don't know I have seen several with pushing 300k miles but then again I have seen a few E4OD's with over 200K also and still ticking.

I wouldn't count that E4OD out yet. We have an E4OD behind a 351 and it still shifts fine with 123k on the clock. That being said, when this thing does throw the towel in, I will likely be doing the same thing that you are.
The E4OD computer will work and the truck will run fine, but it will throw codes when you pull them. It will not light the CEL.

Well, I have found two different trucks. I have not been able to talk to the owner of either truck, but both have been basically abandoned at a auto repair shop and both have 5spds. One looks like a 88 or so, but has a carb, so I dont know if it was converted or what. By the appearence of the truck, i would doubt the trans is in that good of shape, but the bell housing and clutch pedals and stuff like that would still be useful if I could get the truck cheap enough and then just take it to scrap metal.
The other truck is a diesel and also appears to be a late 80s or early 90s body style. Not sure of the miles on either truck since the odometers dont read 6 digits?
The computer not having to be swapped is a plus, because the 1st truck I mentioned has had all the electronics and emissions stuff ripped out.
Anybody know how the OD gear in a E4OD compares to the 5spd??

But, If I do the swap now, I would have a working E4OD in good condition to sell.? Looks like it would be worth a little more as a used but in good working condition transmission than simply a core, right?
thanks for the thoughts and advice
Eric

The diesel is useless to you. The gear ratios are different than the gas version.
I don't know what kind of money you'd get for an E4OD with 100k on it already, if it's been down the dragstrip and hauled a camper that much. Personally, I wouldn't give much for it, expecting to have to rebuild it right after I bought it. I definitely wouldn't buy it unless I could drive it.

With the trans in good working condition, I could allow the potential buyer to drive the truck before taking it out of the truck.
What do you think $3-400?

I have located a high mileage F250 (93ish), but it has a 351 instead of a 460. Will this trans work with my 460? What will I have to change to make it work? I know that the flywheel is probably different, but I would expect everything else to possibly work???
Thanks guys for the help
