1985 was the first year for EFI F-series trucks. So 1985 to 1995 you can check for codes with a paper clip (f150/Bronco). F250HD/350 Federal emission trucks stayed OBD-I until the OBS series was retired ~1997.

There are some OBD-II F250/350 w/7.5L engines starting ~1996 (Cali. and other states with strict emissions). The F150/Bronco were all OBD-II starting in 1996.

Thank you for the help rla2005

It looks like ford drilled the frame for the c6 on the drivers side so it's going to involve much less drilling I'm planning on opening the holes to half inch anyway though the passenger side will definately need drilled though

There appears to be a vacuum port on the back of the c6 do I need it where does it need plugged in at judging by the layer of crud on it it wasn't used before and it drove fine

Needs to be on port vacuum, based upon what vacuum that modal gets it will determine about where the trans should shift. So without that line in place it would more than likely be doing wot rev's aka 4500 shift's assuming I am correct here.

I'm pretty sure that modulator gets full manifold vacuum instead of port vacuum. Try it and see, it won't hurt anything. I would replace the modulator. They get old and the diaphragm fails which lets the engine slurp up transmission oil.

Dixie is right. It gets manifold vac.

What is port vacuum. Manifold vacuum is obvious and where does the timing line go

Someone tell why this is a stupid idea before I go and try it

It's to my understanding that the e4od still engages gears the same way the c6/aod/700r4 does so what keeps me from using an adapter plate and a 4 speed manual valve body to run the e4od hydraulically

Don't know enough about it to say yea or nay. I do know the PCM runs that trans so it might not like that too much.

No need for that... look here:

So, all you need is to come up with a sequencer to operate the shift solenoids based on the input of your choice (lever, buttons, paddles, whatever) and a way to control the EPC solenoid to adjust your line pressure.

The idea is that the PCM opens solenoids to let ATF go from the pump to the engagement parts for each gear whereas the older ones use hydraulic solenoids

But I'm not a transmission expert so I don't know if that's true

Hydraulic solenoids? You mean hydraulic valves. Older transmissions relied on a balance between governor pressure and line pressure to determine when to shift. Clutches were engaged using hydraulic pressure like you mention, and that has never changed except for the new crappity crap cars with their belt drive CVT "transmission" which is the same thing that MTD likes to use on their cheap lawn tractors and riding mowers.

What I am saying is if you want to shift manually, then YOU control the solenoids instead of the PCM. Nothing else needs to change.
