If you're paying to get screwed, you're in danger of getting VD.
I don't think I have VD but I definitely got screwed, lol. I payed $2300 for a "Stage 2, 600HP" 700R4 from Transmission Depot. It shifts nice and firm 1-2, super hard 2-3, and properly 3-4 with light to moderate pedal but, it won't shift at all 2-3 at WOT. I've tried all different combinations with weights and springs on the governor (shifting 1-2 @ 5000 where I want it). I adjusted the TV cable back and forth some. If I leave it somewhat loose when cruising at ~70MPH and I let off the gas it'll freewheel some and slam when I get back on the gas but, it still won't shift 2-3 at WOT. So I have it back tighter until it doesn't freewheel. Trans Depot's warranty says, all I have to do is pull the trans and pay for shipping back to them - useless! I guess I need to find a shop nearby that knows these legacy transmissions. I've been doing a lot of research and all I can find is this kit from B&M, which I saw on another forum that may help to alleviate my issue, who knows? I would love to see a thread dedicated to the 700R4 including
@Schurkey experience with tear down and assembly as well as any more insight.

Here's a snip of what my trans is supposed to have

Sorry for high jacking this thread, it is kind of germane, or at least, similar.
