Manual valve body

I think the concern with street driving the "non rear band apply" manual valve bodies is mainly if the rear sprag fails due to some sort of driving mistake, it may be easy to accidentally blow the trans to pieces and hurt yourself. We have ran several non rear band apply valve bodies on the street with out issue but doing something silly in first while coasting and jamming on the gas may cause trouble.

I would simply suggest getting a valve body that has low band apply as part of its design. This would make for a more streetable safe setup and less likely to cause explosion.

Also, street driving I think you can soften shifts slightly by leaving the accumulator spring in? Not sure if that will help but seems logical that it will (as long as the VB still makes use of the accumulator). Our current cheeta foward pattern VB shifts firm and quicl but not at all harsh, I believe I left the accumulator spring in.
