From what I have been told is no you can not install the 5R110 into a truck with a 7.3L. At least not yet. Maybe some company will make a conversion kit in the future.

 

PCS - Powertrain Control Solutions currently has a stand alone controller under development for the 5R110.

And I believe that Bean's may be making an adapter for it. This is currently being discussed on another forum.

 

So what would be cheaper- a 5R110 or an auxillary trans like the Gear Vendor unit.

It would give you the advantage of overdrive and underdrive for every gear. And it can go in right now.

 

For the price of the 5r110, controller, and adapters... you would have one hell of a 4r100 that would be hard pressed to be busted.

 

I agree, Dirk. Go with a built JW or BTS tranny and be done with it. IMO, that would be the best way to put the power to the ground...

 

the gear venders isn't cheap but neither is all the stuff to put one in a 7.3.
I would imagine 4wd would only add to the fun.

 

I don't think he was asking about pounding on it, he was talking about having the extra gear for the fuel economy?

 

Do you think that the possible fuel savings will pay for the swap? The OD isn't THAT much different. A properly built 4r100 and a properly tuned 7.3 will get decent mileage for it's size/weight.

If you really need better mileage and keep the truck... I have a 3 cylinder perkins diesel that makes 20-35 brake hp.

 

I agree with dirk... spend the money on the tranny u already have... its probably better spent on the 4r100

I do think that a 7.3 with a 5r110 is a good idea though

 

I also wanted to do the swap before I got my tranny built a year ago but as others said you can have a badazz 4r100 for cheaper than a 5r100 swap yet if you got the green it would be an awesome upgrade

 

from my understanding its already been done with the stand alone module , and is being tested now , i will agree that by the time , you spent the money on the 5r110, and the conversion kit ,and labor for the install unless you did it yourself , you could by a bullet proof 4r100, and afford to spend a few dollars extra on fuel

 

What i really wanted to do was fit a 7.3 with either an 8LL or a standard eaton/fuller 9spd. Now that would be the ultimate trans.

 

That would be badazz and could take all the power you could throw at it

 

exactly! The only prob would be fitting it in the truck. Especially with 4wd.

 

Yeah beat it would hang down a little past the frame rails :hehe:

 

I just found a reman 9spd on ebay for 1900 bucks. Thats not bad comparred to adding a gear vendors unit.

 

I have been considering a Gear Vendors unit. I am not aware of the Eaton Fuller 9 spd option. Does anyone have a source for this transmission or a costs?

Rick

 

Well its not really an option that is easily do able. You can buy a commercial fuller 9spd tranny and try to custom fit it in there. I found a reman 9spd on ebay for around 1900 bucks. I'm not sure of the output shaft sizes and such though. It might be more work than its worth, but if you did it you would have the coolest truck in my opinion. Especially if you had the DIY exhaust brake mod also.

 

I've got a nice eaton 6spd in my F700 dump that I love its not that big either...
