Sorry, but no.
Been there, tried that, and Mark confirmed!
They are in deed very different bolt patterns.

 

He called me last nite and said he did swap bell housings. I guess when your 19 and loaded up on MGD ones memory gets fuzzy....

What did the C6 use for speed modulation since obviously there is no manifold vacuum reference to use.

 

It used vacuum. The diesels had a vacuum pump that supplied vacuum to a vacuum regulator valve on the injector pump. It regulated vacuum to the vacuum modulator on the transmission relative to injector pump lever position.

 

So they must have put an electronic vacuum regulator on the C6 equipped PSD's since there is no injection pump.

 

Was that just in the f450 and f550? The 250 and 350 were only available with an e4od right?

 

Not as I remember. I remember the C6 was available on F250, F350, F450, and F550.

But since all of you are convinced I'm wrong, I withdraw my comments. You were there, you saw them not being produced, and you're all right.

I've had enough of this thread. It's just going in circles.

 

i believe you.

 

Mark.. Don't sweat it!

I just learned a lot myself here reading this. Thank you!

 

I'm not saying I don't believe you. Ford has done a lot of weird stuff. Very interesting fact. So is the e4od a stronger transmission or the same as a c6?

 

I never doubt what you say Mark! Your signature says it all!!!!!

 

No offense meant to 444dieselrod, but I take the word of a transmission engineer over "random guy on the internet" any day.

 

If Mark decides to chime back in I'm sure he can correct me.
But they are basically the same except the E4OD has overdrive.
The newer 4R100 used behind the diesels came with 6 pinion steel planets vs 3 or 4 pinion (I don't recall exactly) alum planets in the E4 and C6, so the 4R are even stronger.

 

I'm to the point now that I keep asking question because Im wondering if a guy could gather enough parts to put a C6 behind a PSD in a rat rod. Before I start calling my ford dealer asking for parts I want to make sure what I'm asking for will be in the computer. You can get a C6 pretty cheap. If all I need is some special electronic vacuum regulator and a manual pcm to drop a C6 behind my PSD, that's sweet! I've got a KB-3 IH truck that needs a PSD, C6 and 3:08 gears......

 

And, of course, the electronic control (thus the "E"). Dunno why people take these questions so personally, or go on about what they "believe". The relevant thing is the question of how it can be done. Our trucks have neither engine vacuum nor an injection pump. That doesn't mean it's impossible to run a C6 behind one. But it would have to have some electromechanical solenoid that would draw the pumped vacuum, and regulate it electronically based on load and/or speed, A sufficiently elaborate contraption, informed by PCM data, could do it. The PCM would also have to ignore the _inputs_ from the tranny (AFAIK, the C6 produces no electronic output like the E4OD).

And if we are gonna talk "belief", I honestly _don't_ doubt that Ford would come up with such a Rube Goldberg. They've never let a simpler solution get in the way of using a more complex one.

 

Yes you can!

Auto PCM will be fine if that's what you have. The PCM just sends signals out to shift, speed monitoring, etc and doesn't care if anything is on the other end of the wire or not.
