So where is the first hand? Hmmm?

This may not be an answer you like, but I strongly recommend going with a 4r70w if you want an automatic with overdrive. The fmx flexplate and crossmember work for the 4r70w swap as well, and the factory hard lines can be cut and modified to work with the 4R. I think I remember that the slots in the crossmember just need to be widened a bit. There is the possibility of driveline angle issues with the gear vendors tailshaft, but this isn't always the case. The GV units have good reputations, but their overdrive is .80 I believe and the 4r70w is numerically lower (this is a good thing for highway cruising/mpg). That means you can get numerically higher rear gears and have the benefits of more acceleration, without increasing highway cruise rpm. Not to mention a 4r70w by itself is a ton lighter than an fmx with a GV unit, and since it has lower rotating mass that also means more HP eaten turning the driveline = less efficiency as well. I was damn near doing this swap myself, when I came across a great deal on a toploader...so I'm prepping for that now. Even if they are a good product, which is what I have read, to me they really don't make sense.
