Hi you all.
What does it take to swap a 1999 4r100 with a 1997 e4od tranny?
I have a blown 4r100 and a rebuild beefed up e4od that I would like to use instead.

swapping a 4r100 with a e4od in a 1999 7.3 powerstroke diesel van

You'll have to drill the case for the extra sensors the 4R100 has and then reprogram your PCM for the different torque converter lockup. Not worth it. Why don't you jerk the internals and use them to rebuild your 4R100 and get a new TQ.

What if I use the pcm from the 1997?

 

[Charlie Montana]

That means the intarnals are the same, right?

How aboult the clutch discs?
I heard that the e4od have only one disc and the 4r100 have 3...?

Then your motor won't run. Plus, the wiring pin outs are different. I'm not sure about the clutch packs, but most of the "beefed up" parts are gears/planetaries. Maybe upgraded shafts. All that should swap. Who rebuilt the E4OD?

Thank you.
I will swap the internals as you suggedt.
The tranny was rebuilt by a local shop over here in Norway where I live.
They have rebuilt and upgraded transmissions for the past 25 years.

By the way. They have tested the e4od and given me a written warranty that the tranny can handle the power from my engine. (7.3 powerstroke with 510 hp and 1350lbs of torque at the wheels)

I would take both transmissions back to the shop and have them do the swap.

What rt said. Just not feasable to make the e4od work.

Sounds like you've got some serious mods. What size injectors are you running 250/200's?

I am running modified 250s injectors, ceramic coated cylinders, pistons and heads. Modified hpop, 3/8 inch fuel lines, framemounted fuelfiltr, dual banks turbos and hiflow fuelpump. Compression is 21/1 no headgaskets but o ringed heads.
