Well, MADDOG has done it.. and I can get a fully built 4R100 that should handle ANYTHING I throw at it for less than $3500... (monsterbox)

Is it worth the modifications, etc, to do it? Or are you better in the long run to get the 47RE??

I know.. sacrilege.. but I'm still thinking about it.. I mean once you get the billet shafts and everything done, its already pretty expensive, and you still have a LOT more $$ to put into it.

 

What is a 4R100? Aftermarket trans?

 

Ford automatic transmission.

 

Ok thanks, what do they come in?

 

94-2003 F250 & F350s equipped with the 7.3L Powerstroke.. Also known as the E4OD, is also behind gassers.

 

They dont hold up in them torqueless fords?????

 

Not stock.. but the Monsterbox is holding up quite well.. Not sure if they'd warranty it behind a Cummins though...

 

Why is it better?

Those trannies are known not to hold up to Powerstrokes, let alone a Cummins.

Does it have larger shafts or any other positive trait over the 47RE?

Seems it would be a lot easier to stick with the Dodge tranny.

 

The Monsterbox is fully built and is waranteed to take whatever you can throw at it. That was the only reason I would consider it.

 

Just save yourself the trouble, and call Dave Goerend

Yep.... for 3500 you will be close to all billet and have a tranny warrantied for a long time with gb. If thats not enough you have a lot of work to get that blue ovel mounted up right anyways. If its not perfect than you are way behind whare you would be with the one you have.

I don't understand......what makes the built Ford tranny better than the built 47RE? The well built 47RE's are putting up with insane torque levels.....what is different about the Ford tranny that makes it stronger?......bigger input and output shafts? bigger/stronger planetaries? I don't see the need to add the time and expense to do a tranny swap for a tranny that isn't more durable?

 

Good point

and also the 4R100 came out in 98+ 94-97 was the E4OD not the 4R100. There are quite a few cummins conversion trucks and several with twin turbos that are running built E4OD's and living just fine.

Its the same thing as a built dodge tranny. I believe the dodge tranny has more history with R&D for parts to handle the cummins but the E40D's and the 4R100's are being built to hand quite a bit of power from the powerjokes too. I seem to recall 4wheeler had that superduty on 46" michelins and they had bombed thier 7.3 and had a 4R100 and they put a built tranny in. IIRC they used to tow with that truck too. 46" tires off road all the time and towing with a a7.3 and living sounds like a pretty abusive environment to me

 

I agree that the E4OD can be built to be very strong. What isn't clear to me yet is what the advantage of it might be over a properly bombed 47RE that would justify the added time and expense to do a tranny swap.

 

I dont see any advantages maybe more barriers, being that a stand alone computer will be required for running along with the inputs to that computer would probably make it not as cost efficient.

The E40D and the 4R100 can be run on stand alone computers and harness' but those have to be purchased seperately and tuning them can be a pain. FYI i helped install a E4OD behind a carburated 429 in a 77 ford. would i ever do it again not on your life, the kid is still fighting the little shift point gremlins 4 years later. Ford did have a stand alone harness and computer for the 94 and earlier E4OD's because the 7.3 was NA at that time if you did it that is what i recommend but as to the 4R100 it originally is controlled byt the Ford ECC so you will need something as your dodge ECC will not be capable of sending the right data to control the tranny
