A full manual valve body forces you to manually shift full time, no auto shifting at all. A transbrake VB has a transmission brake in it.

When you engage a transbrake, it engages both first gear and reverse at the same time. This allows you to stall out your torque converter to its full stall speed without spinning the tires on the line. When you release a transbrake, it simply releases reverse and since the transmission is already in 1st as well, it unleashes all the power to the rear wheels.

No need for manual body with the electronic trannies, since shifting the forward gears can be done with 2 wires. The downside is that there's no internal protection against selecting 1st when you're over 90.

Transbrake has to be hydraulic since reverse is not electrically selected. The generation of trannies coming from mfrs now is doing everything electrically, eliminating most of the valve body hydraulics, so hacking these should be easier, or at least save us the ATF bath we all have taken.
