Manual 4l80 ?

Does anyone have a manual valve body 4l80 that drive on the street? How does it handle the stop and go? Does it churp the tires when shifting up and down? I'm thinking of going this route, but I don't know how it would work. I don't drive the car much, but I don't want it to fail premature. Thanks.

Actually since you do retain presure control via either the modulator or some have kept the PCS to the shiftfeel is overall not different from the auto version except you control all the shifts. In fact its even possible for the PCM to continue controlling lockup .

I am running a full manual with the 4L80e and I really like it. I believe I may be having some issues with a tranny mount or something however because when I downshift it into 2nd at around 30mph and 1st at around 15-20mph I hear and even "feel" an unpleasant knock type sound. It will not chirp the tires going into second gear, it will completely rape the tires going into second gear. You can see two long parallel tire marks for first gear with about a 2ft gap between another pair for second gear. I am running a 3500 stall on it right now and it is NOT locking up. I need to get that checked out, it is completely killing my gas mileage and hw mile enjoyment.

If I can get the knocking figured out from the downshifting, lockup for the stall converter, and a nice b&m shifter I will be as happy as I could be.

This is my daily driver, so the full manual may not be for everyone. BUT it makes driving it such a better experience IMO.

Are you having problems with the 6 speed? I plan on doing this in my 93 once the stock trans starts dying.

Yep, 6 speed is whinning like a eaton. It will be any day now, before it turns inside out. I'm leaning to an auto now, rather another t56. I just don't see the manual or clutches holding very long.

^ Is it a stocker or is it upgraded any? Your going to be going through a lot of clutches at your power level. It probably would be a good choice.

Beaflag, were you asking me if my 80e was upgraded any or were you asking about Firechikn's 6-speed?

FYI I took it around for a while today and played on some back roads and all I can say is I have never had a car with shifts as incredibly fast and smooth as the forward manual 4L80e. Now, downshifting it...still working on smoothening that out. Goodluck guys
