I'm a big fan of the bullet proof 727 and from what I hear, the 46 rh/re are closely related to it. so I wouldn't doubt one bit they can be built to handle power.
I just finished rebuilding a 46rh and am working on a 46re. they're about as easy to work on as the 727.
incidentally what is the adjustment specs for the front and rear bands? I've heard tighten to 70 inch lbs then back off 4 full turns in the rear and 2 1/2 for the front band. is that correct?
Let me tell you how I do my band adjustment for the 727/904, A-500/A-518 and 42RE-48RE. If there is a way I can make the adjustment while the pan is off that is how I do it. I like to have a visual of the band apply lever and the support. I like to set the band apply lever 1/4" away from the piston.
Now, on the other hand, here is the procedure direct from the Factory Service Manual from 1972.
