As the title says, has anyone put a c6 behind a powerstroke.

Can I run the stock powerstroke flywheel and if so what torque converter will bolt to the flywheel and work with the c6.

Reason I want to do this is I have a stand alone engine harness I built for my 73 with a manual trans. I don't want to go threw finding all the connectors for a e4od or 4r100 and the speed module and rebuilding the harness. This setup is going in my wheelin rig and I will be running a b&m shifter and I can't do manual shifting on a e4od do to not having the computer control the roc. Only going to use 1 and 2 occasionally 3 driving down forest roads and I like the reliability of a c6.

 

The C6 was available with the Powerstroke from the factory in 1995 and 1996.

Automatics don't have flywheels. They have flex plates. They are two very different parts.

 

I've never heard of the factory putting out a C6 in the powerstroke. I'd like to see one. How could it be without the electronic capabilities?

OP, I think it could be done. I'd talk with a very reputable transmission builder.

 

I have never seen a c6 that application. I would love to see that.
I spoke a while back to my converter builder. He said he could build a hybrid converter to make it happen. We planned on reverse manual valve body maybe with a trans brake...that project is back burner tho.

 

Um, the same way they put gazillions of ZF5s behind PSDs.... If it were the other way 'round (putting an E4OD in an vehicle with no electronic/digital control), you'd have a challenge. But the only thing the C6 needs to shift is vacuum, and preferably something to kick it down to second gear at WOT. Mark Kovalsky would probably know how that is accomplished with a PSD+C6. I reckon either there's a kickdown solenoid on the transmission, commanded by a particular go-pedal position % from the PCM, or they just figure sorry, no WOT kickdown, downshift yourself.

I think you'd likely find a PSD+C6 only in fleet/U-Haul application, a C&C truck.

 

I know there is a difference between a flex plate and flywheel but idi engines have both with the c6 in 88.

I am putting a manual valve body in so I will shift it not the trans shifting so I don't need the vacuum modulator and kick down lever.

So my best shot is to have a convertor built.

 

C6 requires a vaccum mudulator. No true vaccine except for power brake system.
Also c6 uses a mechanical linkage for kickdown. Not sure how to overcome that (manual vb). The modulator could be converted to mechanical like a commercial application.

All in all it shouldn't be impossible at all.

I would be using the e4od flex plate to start with.

 

I believe you will find idi to be 4 stud vs psd are 6 stud.
I was looking at a custom unit but wanted to do more studying before going forward.

 

If there was a C6 behind a PSD, then there should be a TC built for it, right? Hmmm......I may have to make some phone calls....

 

I was needing to check bell to front of converter distance

Engine plate to face of flex plate distance and converter pilot diameter(I think I measured but it's been a while)
A bushing or custom diameter pilot may need installed on new converter.
There again I needed to finish my homework but have stacks of trans and parts to compare if I can help.

 

I have a 86 c6 in my shed but I don't have an e4od to compare to and the issue with running an idi flex plate is if I remember don't quote me on it is idi is external balance and powerstroke is internal. Other question is will an idi flex plate bolt to a powerstroke crank and if so I just get my c6 idi flywheel rebalanced and go that route.

 

And before someone decides to correct me on the flywheel. With the 80s idi with a c6 they ran a 2 piece flywheel which is cast and then the flex plate that is how ever thick bolts up to the crank with the flywheel

 

The IDI and PSD crank shaft bolt patterns are different unfortunately. Would be nice if they were the same. I have had a project in mind for a couple years, and this is one of my problems also. When ever my project gets back on track, and the time comes for the TC, Aaron is gonna get with his guy and have one built. Probably be the best route unless we could dig up one these C6s that was behind a PSD.

 

I want to know the application. I have never seen it in real life. It will have to be box van or something off the wall. My converter guy didn't know a shelf application that would have come from . If he didn't know then I'm confident they are either very rare(like hens teeth) or nonexistent. He is old school and been doing converter work since the 70s so I sure would have thought he would know

 

U-Haul C&Cs, from what I've read. Never seen one in the flesh.
