LS3 with 6R80 Transmission (Ford) Does anyone know if the 6R80 transmission (F150) will connect directly to an LS3 engine? If not, do you know where I can find an adaptor?
Thanks.
Thanks.

It will not. I’m not aware of anyone currently making such an adaptor, but I’m sure you could have one made. I have to ask, why not use a GM transmission?

I had a 2011 GMC Sierra and hated the transmission. From the time I picked it up from the lot it was jumpy, skippy. It drive me insane so I don't trust the GM 6L80. The Ford version 6R80 seems to have a good track record.

Getting a Ford tranny to talk to a GM computer would be impossible. Get yours reprogrammed correctly and you will be happy.
Your engine is a Gen IV, not Gen III. This is in the wrong forum.

I absolutely love the 6L80 in my 12’ Silverado. It’s my favorite part of the truck, other than the bow ties on the grille and tailgate.
