I've read that lockup 47rh dont like the hydro fluid, so a 700r4 prolly won't fair much better, especially since its a lockup as well, or at least that's how we set up mine, automatically locks converter when I hit 4th gear
We ran it in a 47re just fine with lock up. and we've ran it in 518 lock up gassers fine, but we ran a bottle of lube guard in it also.
I want you to know also I'm not arguing just putting out what has worked for me.
