Do Not, under any circumstances, do a wot shift to 4th.
4th is "Special" in these trannys, where there's a race condition on the Direct Clutch vs the Intermediate Clutch.
If you win, you can break the intermediate shaft into Three Pieces, which is very hard to do.
A 4th to 2nd shift is also discouraged; unless it hits 3rd first, it breaks shit.
You really should read some of the stuff here...
