Hey Everyone, I have a 94 F-150 5.8 E4OD 4x4. My auto trans is going bad and I was thinking of converting it to the M5OD 5 speed manual.
I know that I will need to:
Cut a hole in the floor for the shifter
Install a 3 pedal setup in the cab
Install a clutch master cylinder on the cab
run the hydraulic line down to the clutch.

I already have a transfer case for the 5 speed

Can anyone else think of any problems I might run into with this project?

 

If you can find one before you find a M5OD....go for a ZF5. MUCH better transmission, both in terms of longevity and gearing.

The M5OD has such a TALL Reverse gear, if you have to back up a trailer, say goodbye to your clutch! At least your 4x4 so you can just stick it in 4 LO but still.

I hate my M5OD, and if ever something was to happen to it, ZF5 it is!


However, finding a small block 4x4 ZF5 is pretty hard to find.....


Otherwise, sounds like you already know what your doing.

Might have to mod your current tranny cross member or get one from a 5 speed truck.


And you will need a clutch pedal assembly from a 1992-96 F-series, other years wont work.

 

The Mazda tranny was never placed behind a 351W. It is not rated for the power a 351 puts out and is a light duty tranny. You will need a ZF tranny out of an F250 that will hold-up and has the benefit of a granny gear.

Here's a conversion thread:

Computers made to run with auto trans. have slightly different programs. I have interchanged computers with EEC-IV, like yours, without noticeable glitches, but that does not mean you will be happy with the way your E4OD intended computer behaves running a manual trans. You likely will get "check engine" codes generated, as your computer tries to figure out what's happening with the E4OD which ain't there no more. At that point, you will want to get the correct computer for your application, as specified for manual trans. impish

 

^^^^ That to. A C6 engine computer will also work as the C6 doesn't use a computer so it's just like the standard transmission computer.

 

Imo the m5od will probably hold up ive never and any issues and I pull alot of weight for well over 200,000 miles I like it better than my zf for intown driving

 

Probably?, What's an M5OD rated for? There is a reason Ford did not put it behind a 351W and the torque it can deliver. Torque input is different than what you tow.

 

Go for the ZF right off the bat. It's designed to be a sturdy truck transmission so it can take whatever you throw at it.

 

careful.many people think their E40D's are going bad,when in fact the issue causing what seems to be major is simply caused by something small with it's electrical system.
can you describe the symptoms and or any codes your getting?

yeah,i don't miss that thing at all.last f150.

 

I say probably because I have never had one behind a 5.8 and I only talk facts I know mine held up to win the truck pull it seen tq that day
