I have a 90' f250 7.5l with the e40d... started leaking trans fluid and lost reverse. It's my plow truck don't drive it much but need reverse. I found a 97' 7.5 e40d for cheap locally... will it bolt in? Seen and heard conflicting things any help would be great!

 

Yes. As long as they are both e4od transmissions for a 460. From what I have read the valve body / solenoid connector changed in the mid 90’s. I’m sure others will have more information about it than I.

 

Where is it leaking from?
If leaking from front of trans, torque converter area, the front seal is blown, possibly the bushing as well.
If its leaking from the rear, rear seal.
If trans heated up/overheated, fluid can puke out the breather valve at top, and or out the dip stick tube.

The 97' will bolt in, but you will fry your 94' EEC. There are diodes in your 94' trans solenoid pack, that the 97' does not have. Diodes moved from trans to EEC in 95'.

Two(2) options:
1) swap your 94' solenoid pack into the 97', and trans wire harness.
2) swap the 97' EEC and trans, assuming both are Mass Air Flow(MAF). Can you get the 97' EEC with the trans?

If you 94' is Speed Density(SD), option 2 will not work, without swapping complete engine harness, EFI harness, and all sensors.

 

It's a 90 not a 94

 

Oops, lol. I have a 94'.

No difference, . 1989-1994 early and 1995 and up.
Two different styles. All same 1989-94' with diodes, and 1995 and up have no diodes in solenoid pack.

 

Any cheap e4od that cant be driven is like rolling dice with a set that is loaded for the house and you are NOT the house.

Check that.... any transmission, c6, zf, overdrive whatever that cannot be driven is worth core and expect to rebuild it and you wont be disappointed.

Does it come with torque converter? Check it for play... smell it... roll em baby!-)

i like the c6 and zf5 because they are solid and reasonable to rebuild and also reasonably possible to do at home.

when you HAVE to have an automatic overdrive transmission, expect to pay for it.

the e4od is a monster transmission too. Man...putting that thing in at home....wow. You can do it though.
because that beats what the shop is going to charge to do it.

geez, plow truck...so its 4x4? That’s actually sounding like fun now!-)_

the last quote i received from powertrain on a reman’ed e4od was 1800$. With a 3 year no fault warranty.
used them on an overdrive trans for a Chev tahoe 4x4 5 years ago and it still runs good today. Don’t tow with it though and not plowing with it. And rarely, as in never, sees 4x4 action.

Anyway, good luck and let us know how it turns out.
best regards.
