C-6 TRANSBRAKE ?

when in first gear with the solinoide activated,what is actuall ygoing on in the drum clutch area,is it the low/rev clutches being applied,and when the sol is deativated the low/rev clutches release,or something differnt,any ideas?

As far as I know most if not all transbrakes lock the trans in 1st and reverse gear at the sametime.

When you hit the button, it's applying the high/reverse clutches at the same time the low/reverse is applied. Chevy and Dodge use reverse, but Ford uses high.

It will all depend on who's? valvebody you have?, High/reverse clutch&lowreverse clutch is the most common, any valvebody that you have to push the brakebutton to back up means it's not applying the low/reverse and only relying on the rear sprag to hold on the brake
