727 no reverse, forward in neutral after rebuild

Thanks for the info. It has a no low band apply valve body. Should I keep that and go billet steel front drum and piston, bolt in sprag, and billet low rever servo kit while I'm messing with it? I know change vb to lba would add another layer of safety but trying to find happy medium of safety and cost on a car that is only really street driven right now. Thanks again

I would certainly recommend the LBA valve body for your exact reason stated. Especially on the street, the sprag can be beaten up badly when at stop lights and starting out in first gear and burning tire. If you have a higher power street car that has no issue cutting the tires loose on the street, your at a lower risk than the guy who barely has enough power to turn the tires on dry pavement running a non LBA valve body. Yes highly recommend the LBA valve body. But if you only have money for the bolt in sprag, and billet front drum, and billet solid l/r piston, you are still making the transmission much much safer. The good thing with the valve body, if you have to hold off on buying one because a lack of funds, you can always buy one later and swap it out while the transmission is in the car.

I am currently building a 727 for a street car that is getting an automatic shift valve body.
The automatic shift valve body does not apply the low/reverse band when in drive, but when put in manual low it does apply the band. That is as safe as I can make it given the valve body he is going to be using. He is getting the bolt in ultimate sprag, billet front drum, billet low reverse piston, and some other good upgrades.
