I haven't done it, but I heard it's not a real fun job. You need the wiring from another truck, which it sounds like you have. Are the computers the same between E and F and 2x4 and 4x4 anybody? You will also need the tranny out of a 4x4. Other then running the wires it should be like any other swap. Your English is good but I can't figure out this one line, "But, I need som info about mines not to fall in, if there are any" I think som = some but i can't figure out the rest. Also, the E4OD ISN'T known as the most reliable or longest lasting tranny there is.

I think what he means is, he wants to watch out for pit falls one might encounter. I can appreciate wanting to swap the E4OD for the C6, to get the locking torque converter and overdrive gear, but I'd much rather throw a Gear Vendors unit on a C6. I realize this would be an expensive proposition, perhaps especially in Norway (although with the weak American dollar, maybe it's cheaper for him). [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Im almost done doing the same thing . Wasnt to bad , just very time consumping . I had a complete donor truck and swaped all wiring harnesses , motor , steering column , tranny .

If your just swaping the tranny , you'll need the get the driveshaft shortened (170$) . I had to cut my front gas tank gaurd down a bit so it dint rub on the tranny .

The tranny mount is different , its a little longer and mounted a bit further back towards the rear end . If you could get the one that was on the e4od it might line up....my truck had the holes already .

Ran new tranny cooling lines , and put in a secondary cooler wich i think is recomenneded with the e40d . Also the shifter thingy is different , so if you can get the rods that goto the steering column , that would help .

Thats all i can think of , although ill add that there was absolutly no room to squeeze this tranny in with my reguliar cab truck . I actually put the tranny in first , then the motor , and it was TIGHT , too a while to get the TC lined up and boldt the bellhousing . Like i said i actually had to cut the gastank gaurd down because of the rubbing .

Hope this helps

Thanks to all of you, for your info [img]/ubbthreads/images/graemlins/smile.gif[/img]

I'm aware that the C6 is a better gearbox, but as stated by "Mel" I really need to get the RPM's down to save gas (diesel in Norway cost about 5.7$ a gallon).
And I also want to increase the speed of the truck!

I'm hoping that some of you can tell me if the computers the same between E and F and 2x4 and 4x4? Because my computer came from a E-350 2x4!And the gearbox is from a F-250 4x4!
Both 7.3 IDI..

I also have one extra oilcooler, that will be mounted!

Larry, you wrote:
"If your just swaping the tranny , you'll need the get the driveshaft shortened"
This means I need the driveshafts from a F-250 delivered with E4OD??
Or that i also need to make the driveshaft to the frontaxsel longer, right???

Sorry about this one: [img]/ubbthreads/images/graemlins/phoney.gif[/img]
"But, I need som info about mines not to fall in, if there are any"
Thanks Mel, your transelation is correct!
"I think what he means is, he wants to watch out for pit falls one might encounter"

Thanks again all of you [img]/ubbthreads/images/graemlins/smile.gif[/img]

I believe i read that the computer for a 2x4 IS DIFFERENT than from a 4x4 . But you might want to wait for someone who knows more about that to chime in .

Yes , you'll need to lengthen the front drive shaft .

Like i said i had an entire truck , so i just stole his front drive shaft rather than getting mine resized . I couldnt with the back because he had an extended cab and i dont , his was actually a 2 piece shaft .

I'm telling you right now the hardest part is going to be wiring it up . Theres alot of wires involved with the tranny , wich is why i took the time to take everything apart and swaped all the wiring harnesses . I couldnt imangine running all those on my own .

But in any case i bought the wiring schematic for 12$ here>

Turbo69 just pulled a computer/e40d from a Van and put them in his standard 4wd truck with good results.
His knees were killing him.
I presume everything would be simular to an 86, with one exception.
The rear differential has a speed sensor used by the computer.

He finally got frustrated at issues other than the trans and has gone newer Dodge cummins.

He might still respond to a pm, or might be found on www.[censored].net

If you really get stuck, send me an email at leefrankpierce@hotmail.com and I will see if I can give his email out.
He has been known to be reall helpfull, so I am shure he wouldn't mind but I do want to respect his privacy.

On another note. Much cheaper to put big old tires and change the diff gearing.
Go to www.ring-pinion.com and check out their calculators.
Stock 2x2 tires are 30 inches, common 4wd are 33's. I think you can go as tall as 3.07 in the rear but I am not shure about that. 3.55's and tall tires may get you there.

Thanks again all [img]/ubbthreads/images/graemlins/grin.gif[/img] I'm glad I startet this thread (it has been realy helpful).

Lee, I hope/think you are right about the controllbox... (time wil show)..
But how did the gearbox effect his knees??

And regarding the speed sensor on the rear differential, I think this is mounted on my vehicle (I have a speed sensor for the rear axel ABS).

And one question: About the tranny mount, can I use the one I have for the C6 (with some small adjustments) or do I need to get the original E4OD-mount?

Thanks [img]/ubbthreads/images/graemlins/warmsmile.gif[/img]

You can use the mount , but will have to make adjustments . You will probably have to lengthen it because it sits further back on the frame . And you may have to drill holes in the frame to mount it .

if the van computor used the speedo drive for roadspeed just use the t/case speedo drive if the van only used the rear abs to run computor and speedo then the van computor will not work as you have no way to run the signal through the psom module in the electronic cluster used in later years <approx 1992/93 up>
