Some valve body and tranny questions.

[Highway High]

Ok, first off, I have a '91 lx 5.0, with flowmasters and a k&n filter. The tranny slips quite a bit, (I will gun it, it'll rev up to like 4k rpm, then finally catch and shift), and this is growing to be quite annoying. The transmission just seems very sloppy. What sort of a difference would a manual valve body make? Am I going to need a whole new tranny? A rebuild? What? Also, I'm still unclear as to what a valve body is, I've heard a lot of talk of them, but still don't exactly know what it is. What kind of performance gains would I see from a manual one? Also, here pretty soon I'm getting some catless x-pipes and some 4.10's, if that means anything at all.

Have you checked the fluid level? If the fluid is fine, then you've got bigger problems than you think. These things don't slip for no reason. Probably time to think about a rebuild. Check out www.lentechautomatics.com for one of their valvebody kits after you get it rebuilt. the street terminator is a good one for the best of both worlds.

Well what IS valve body? What does it do?

Think of the valvebody as the brain of the transmission. It is a series of valves and passages that trans fluid flow through to control your shifts. It resembles a maze of small passages that the valves control through line pressure, throttle position etc to make the trans shift automatically. When you have a manual valvebody, you have to shift the trans to make it change gears.
