Transmission Compatibility
At work we have 2 - 2005 F550 Super Duty Service trucks. Truck #1 V-10 gas, motor blown. Truck #2 6.0 Diesel, transmission dead. From my research on the forum is does not look like I can take working transmission from truck #1 and put it into truck #2, is this correct?
I can check the door stickers when I am up there next but it appears that they came with different transmissions and will not just bolt up or work with the electronics.
Thanks for any insight.

Nope. Although both trucks are equipped with the 5R110W transmissions behind different engines. There are internal mechanical differences as well, not to mention the transmission from the V10 gasser will not bolt up to the 6.0L diesel rear cover.

The hard parts wont hold up to the torque of the diesel. You would be better off having the transmission rebuilt to a bullet proof spec. It will last the life of the diesel then. . There was a guy, don't know if he is still around, that would rebuild transmissions with his own hard parts that were superior to Fords. BDS, or BSD or Brad or something along those lines, and the price wasn't much more than a standard rebuild.

Other than the torque converter, the V10 trans will work just fine behind the 6.0L. If you were to install a 6.0L torque converter in the V10 transmission you would end up with a better transmission than the 6.0L had originally. Everyone else that posted above is just plain wrong.
There are only two differences between a V10 and a 6.0L transmission in 2005. One, the torque converters are different. The 6.0L has six studs and the V10 has four studs. The second difference is the intermediate one way clutch. They are both the same strength, but the one in the V10 has a lower allowable lash. The 6.0L one causes clunks on the 2-3 shift. It wasn't super noticeable on the diesel, but it was awful on the gas engine. So they spent the money for a better one way clutch to solve that issue. I was not successful when I tried to get that clutch in the diesel.
There was only one bellhousing pattern for all 5R110W transmissions. All engines that used the 5R110W used the modular engine bolt pattern, including the 6.0L and 6.4L diesels.

What Mark provided is good information.
I was unaware of the intermediate clutch difference between gas and diesel, but was aware of the torque converter when I swapped a 5R110W from a 2006 F250 5.4L into a 2003 F450 6.0L. All works fine and the 5R110W has over 15k miles now behind the 6.0L.

Thanks for all the reply's. I will double check the door stickers when I get up to that jobsite and make sure they both list the same transmission and leave the people higher on the totem pole decide if they want us to move forward with this.
The transmission that died was diagnosed with an internal pressure leak. It works for a few seconds after you start the truck then acts like it sucked air. I can usually put it in gear right after starting and move it a few feet. Only reason I came up with the sucking air thought is by engaging the pto and watching my hydraulic pressure on that system. The pto will come right up to pressure for a few seconds then the needle will bounce a few times then drop to zero.
Estimate to repair the transmission was comparable to installing a rebuild. That was already decided against as either repair cost more than the truck is worth. But if we can swap transmissions that puts us back into a workable solution.

The appropriate way of viewing the situation is not what the truck is worth if it were to be sold, but instead what is it worth working? If a transmission rebuild is all that is needed to put a truck that im assuming has paid for itself already back to work and further its ROI, then that would be what I would do.

I had run across that information, but could never confirm. The transmission is holding up and I change fluid and screen every 5,000MI. Nothing looks or smells out of place.
