Hey everyone, I am new to THIRDGEN.ORG, I spend the majority of my time over on SYTY.NET. Ive built 4 700r4's successfully and have never had a single problem with them. Except for this one. I build the trans with a few minor mods nothing too fancy. Just more clutches, blocked 4th accumulator, like I said, nothing major. I replaced all seals, clutches and steels. So I get everythign back together and everything feels fine. At first it wouldnt go into third gear but I drove about 60mph and switched gears back and fourth from 2nd to third and it went in and didnt have a another problem with it. Well, then I couldnt get 4th to come on so I tried the same thing and nothing. Upon further testing, I noticed I had no kickdown when I would floor it. So immediately I thought Ild better park it before I take something out. So I double check the servo and it looked just fine. I pulled the governor and it loked fine. I pulled the valve body and noticed the accumulator valve was stuck in the sleeve, I changed sleeves. I double and triple checked the TV. It moves freely and when the pedal is pushed to the floor the TV goes all the way in. So I put everything back together and the 1-2 shift and 2-3 shift is way better than it was, but, still no OD and no kickdown. I dont know what else to look for here, I also switched TV cables as a just incase and nothing. If anyone has any ideas please let me know. Is there somethign I couldve done wrong in the case? Any input is greatly appreciated.

Pull the valve body back down and chect the actual throttle valve back at the end of the bore its sticking .

 

Yeah I did that like 3 times. Even took it to my trans shop near by. It moves just fine. Im stumped.

 

Put a pressure gauge on this and see what the readings are at the different throttle openings. This might give you an idea as to what to look for.
