Lost reverse, 3rd and 4th

[Limited]

My trans just up and lost 3rd and 4th gear, plus reverse, about a month ago. I replaced the gov solonoid and that didn't change anything.Its a full billet DTT with a Goerend VB and ATS TC. Bit of a frankentrans, but it has always been pretty good until now. Thinking about swapping a stock VB back in just to see if I get the gears back. If you rev it out for a while in 3nd it will eventually go into 3rd so the gear itself is still there, but I havn't been able to get it into 4th. Reverse just isn't there, won't go in at all. I'm thinking valving....ideas?

Typo, if you rev it out long enough in 2nd it will eventually go into 3rd.

You have lost something on the front clutch sounds like.
The front clutch is used for reverse, 3rd, and 4th.

I just called DTT and they said to adjust the bands, particularly the band that is adjustable from the outside. I'm going to try, but I can't see it being so out of adjustment that I lost reverse.
