How many racers with a TH400 Transbrake car push it into Nuetral

I have talked to the guys with that make the Clean Nuetral valve bodies and it seems as if the only difference is Nuetral is behind high gear

Do you push your TH400 in Nuetral by passing over 3-2-1 into Nuetral ? I dont see any issue with it because your passing over the gears,, your not making enough fluid pressure to engage clutches etc when passing over them (kind of like passing over reverse when going from park to low gear)

I know this is an opinion subjest so let hear them,,,

Opinions?

Just for yours and everybody's information, TCI just came out with a Clean Neutral, reverse pattern Trans-Brake Valve Body for the TH-400. It has a second neutral after high gear. Part #221505.

I have never put an automatic car in neutral. Several of my friends have ridden guard rails and one died from a suspected wrong selection of gears in the lights. Times have changed and equipment upgraded but it still scares me to think about it. With the fourth gear neutral after high that sounds good.

Joel makes valve bodies with an electric solenoid neutral. He is building me one for a C4. Mike Pustelny also has one of Joels transmissions with an electric neutral. I know Joel also builds a lot of transmissions for a lot of Stock and Super Stock racers.

I used to go all the way to neutral, probably did it 1700-2000 runs, but now I just put it in 2nd for coast down. Coan standard brake V/body.

Doesn't shifting into neutral at the line have something to do with spinning up the forward/direct drum up past its rpm limits? Or do some valve bodies prevent this?
