No low band apply okay for mild car?

I have a "no band apply" unit, got it used, fairly reasonable. One thing "that scares me" is let's say you are in an auto X. Or just banging around curves on a back road. Seems to me, being in low, "hitting" the throttle from a coast, over and over, might be a little uh, "bad news?"

One reason I'm considering an "apply" unit

So far as I have found? there are no? reverse pattern "apply" VBs.
