Does anyone know where I can find a 4L80E full manual valve body? Someone has to make it. I've searched and searched but can't find one. I need a reverse pattern fully manual valve body with trans brake.

 

patc sells a 4l80 with a fmvb... you can probably buy one from them

 

probabley not the forward manual valvebody is a kit transgo sells, but a t-brake plus one of those would have to be invented. right now it doesn't exist, but hey i wouldnt mind tryin

 

ck transmissions offers one with a trans break... so does rossler

 

Are you guys talkin about the whole tranny or just the valve body? Have links?

 

interested as well. Any more info on this?

 

We can't link or provide phone numbers for non-sponsors because it's against the rules. But if you google Rossler Transmission you'll find all the info you need.

 

I dont think that the Rossler Tbrake is for a manual vb.

 

if none of the sponsors carry what the guy is looking for, then posting another company is not competition for them.

my rossler brake is on a standard automatic valvebody.. which works great for me.. why let me mess up a shift when i can let it be done perfectly every time for me?

 

Agreed. No need for manual with an electronic tranny.

 

I agree but I still think it's againt the rules to post a link or direct phone number. But I very well could be wrong.

 

i guess pm it if you let that sort of thing bother you

 

I have done a bit of research and have yet to find a single person that has a perfectly working 4L80 w/ manual valve body. Seems like there are always issues. I gave up on it and am going 3 speed with a GV OD down the road.

 

what's the shifter in your car??? looks like a b&m pro-ratchet..........

but you're saying you have the computer controlling the trans still??

im confused.

 

Wow they make 4l80 manual valve bodies? AWESOME LOL

 

i dont know about the manual valvebody but there is trans brake for them now

 

its a B&M quicksilver

you can put in ratchet mode if you want to manual shift or just drop it in D as seen here:

 

What issues are there with the full manuals?

 

I have heard of problems downshifting. One guy could only down shift above 30 MPH and the other guy couldn't don shift unless the car was stopped. Also pne of them would bang really hard into gear when stopped.

 

I’m not an auto-trans expert but this idea needs clarification. An important advantage of a partially electronic valve body is that the hydraulics are simplified by the inclusion of electrical valves (solenoids) rather than mechanical valves. Reverting to the old-fashioned type of valve body seems so impractical to me as to be essentially impossible. If, by fully manual valve body, you mean “stand-alone manual controller” then it makes sense. I think TCI makes such a controller for the 4L60E and 4L80E. This, I assume, is an independent (of the PCM) electronic controller that can simulate a fully manual valve body. Forward or reverse is probably optional.
