Auto trans recommendation for 360 crate engine

Thanks for the info. The shop that wants the off the shelf solution is in San Antonio. I don’t think he will be interested, but I will forward the info.
Off the shelf is nice. One of the reasons I didn't do it. I know 46RH uses electronic OD, and 3rd and OD lockup. And I *think* A518 = 46RH. So I didn't want to deal with that, although there's probably an easy solution.
