5R110 to 4R110 swap? Who has done it?

[7.3L PowerStroke]

*The reason im asking is because I found a amazing deal on a built suncoast 4r110*
I was curious in how hard this would be to do? I was reading in DIESEL POWER that a fella had this done on his truck its the black 2010 that makes 1100hp.
Just wondering if its hard or easy?
I could not find anything in the search.

Thank you

You need an aftermarket controller, and I would imagine you're going to need a different converter than what's in that suncoast, as it will likely be a 4-stud. I am not sure if the bolt circle is the same on the 8 stud as the 4 stud.

I saw that article and was like WTF did He do that for LOL

that had to be a pain in the arse and for what ?

A 4r for a 7.3 will not work on a 6.0-6.4 wrong case.

The 5r is what will not hold up to big HP, thats why many are swaping to a BTS 4r and dropping a couple of tenths on the strip. We just shiped one to a customer with a 6.4that's planing over 800HP.

they never had a 4r for a 6.0/6.4 but the swap was done in the magazine article so IDK what they did for adapters but it was accomplished



or are you saying there is a 4r that works ? confused LOL

I'm sure NADP would choose to disagree with you...

Sure they will but facts are facts...4r will drop ET's over a 5r..

NO adapter is needed when using a BTS 4r100 to replace a 5r.

We are a BTS dealer..and drop ship all over the Continent, email me or PM for pricing.

They are plenty of guys over on PSA swapping over to the 4R's. I even know a few 6.0L guys. Faster spool, drops ET's, shifts are more predictable at WOT, etc.

6.0's seem to do alright with the 5R110. However, 6.4's eat them alive above 700-800 HP. The 4R100 isn't the best option either though. The guys at MPD have done several swaps, and they help, but they still have issues with the shafts not holding up. Those guys are trying to get a transmission to hold behind a 6.4L making over 1,000 HP at 7600 lbs though. That's not something easily accomplished. When the transmission does hold and the shifting is spot on, the truck moves out.
