Whats an upgraded valve body in your tranny do? does it just help with line pressure and lubrication? if so, how does it do it vaguely? what does it do?

Pretty much, It directs fluid and regulates pressure..

Changes shift firmness and timing, boost line pressures helping to keep the clutches locked up.

So would an upgraded valve body be a good investment, Possibly tranny saving, on a truck with mild modifications?

An upgreaded valve body would be a very good investment.

whats a good valve body to go with? I was looking at the one at beans diesel

BTS or RacerX gets my vote..

I'd go for a BTS myself. A valve body isn't overy expensive but the problem is yes it can help prolong a transmissions life. However when the tranny goes it's going to be toast too from the debris getting into it. So if you have a very mild build then go for it and hope it all holds out. If you're going with a bit higher build then save your money for the full on transmission build later.

So are you saying toss a VB on it and call it a day? (Without putting in a better tc..)
