Manual Valve Body

Do you have a particular reason why you want to go that route? With the way that transmission is controlled electronically you can have full manual shift control without going to a full manual valve body.

Manual control without the need for a clutch. How can I do that without the manual valve body?

[Craig@Bowler]

Well, there will be clutch packs in that transmission regardless of how you are controlling the shifts. Going to a full manual valve body will allow you to run that transmission without an electronic controller, but you will always have to shift from gear to gear every time you want to change gears. If you keep the TCM in control, you will have fully automatic shifting and the ability to manual shift, so for a street driven car it just makes more sense to us to keep it electronically controlled.

So is it possible to run a sort of gated shifter on just a normal 4l80e and control the low end? With it fully cooperating

Yes, as long as you are still using the shifter in conjunction with a transmission control module. If you go with full manual valve body you will lose the "automatic" shifting and it will have to be manually shifted into each gear, so you will have to physically put the gear selector in 1, then 2, then 3, then 4 and back down again as you need to down shift. If you put it into just "drive" or 4th gear it will always be in that gear if that helps clear it up.
