Thanks SubFord, I just wanted to make sure on that before I burned it to the ground.

 

What do you mean "before I burned it to the ground".

 

Just being funny. Im a machinist by trade and when I do my own electrical work I make darn sure. Thats all. Im going to buy a 2 pole switch and run the P/Y wire to it. I re read post #2 and got it then, along with th attached drawing. Good information on this site and Im still learning this computer control stuff.

 

I'm just curious as to why ford designed the E4OD to have soft car like shifts? These trannys are in trucks and I would think they would have higher line pressures? I remember my 94 4R70W as having decent firm shifts. It's also interesting that on the E4OD and 4R100's at least to what I have noticed is the Torque Converter engagement at the same time as a shift. Any how Thanks for the replys.

Oh ya Sub ford Just curious were you are finding these cool electriacal diagrams. We have ALL data at the Diesel shop but I havent been able to find anything as extensive as yours.

Just a FYI My buddy at work has a 2000 F-250 Diesel and we researched the tcc wire on his and it still is a pink with yellow tracer according to all data.

 

The electrical diagram in post #7 is from the 1992 Electrical & Vacuum Trouble-Shooting Manual.

The diagrams & charts in post #11 are from this URL:

But they copied it from the 1994 Powertrain Control/Emissions Diagnosis OBD I manual.
1994 PCED OBDI Section 6A: EEC-IV Pinpoint Test Procedures, TE--Transmission Fluid Temperature (TFT) Sensor Index, INTRODUCTION.

I cant find the Pink/yellow wire coming out of EEC. Found a peach and yellow and that wont it. Looking at the EEC , where about should that wire be ? Sorry for so many questions.

 

Here is a link to a diagram:

But you should be able to find it up on the fender in plug C103.

Here is a link to a diagram of C103.

Pin 53 is Brown/yellow on mine, 93 F-150 351 W E4OD 4x4. I'll cut it and see. The other wire I cut I had too splice back.

 

The above diagrams were from the 1993 Ford F series Manual.

 

Subford , I looked closer and it is purple/yellow. Maybe thats P/Y

 

Yes P/Y is a Purple wire with a yellow stripe.

 

The wire color in the above posting is wrong.

It should have read "circuit #480, a Purple wire with a Yellow stripe".

Sorry about that, I saw P/Y and miss-read it.
Pink would have been PK/Y.

 

No problem, Just got back in from test run and that is it. Thanks for your research. Might burn a little more gas that way but pulls better and will just flip the switch back on for normal driving. That was a good learning experience. I cant imagine repinning for MAF conversion.

 

So let me get something straight here... A switch on this wire disables the TC from disengaging when you let off the throttle so it rides the gear down like a manual transmission would? The transmission can still shift gears right?

 

you can get a lot of the wire info at www.fordfuelinjection.com
also test procudures for all the sensors
