700r4 problems after rebuild
So I'm having some problems not that I finally got the car on the road. I can not get the trans to shift into overdrive. Other problems to note, does not downshift from 3rd to 2nd at highway speeds when I go full throttle. It also shifts into 2nd and then into 3rd by 25mph. I have adjusted the TV cable so that at WOT it is guitar string tight. With using the fine tune button I was able to get the shifts alittle higher but no overdrive. I've tried manually shifting from first on up at 5k each shift but no overdrive. To rebuild I used a standard kit for gaskets and clutches, a corvette servo, and a .500 boost valve. I just can not get my head around this problem. I feel as if maybe there is something wrong internally, letting the pressure bleed out and it is not getting high enough to shift correctly.

As for overdrive, pull the servo line up out and check that it is correct. Also check the seals on it for one being rolled over or such.
The band, which the servo applies, is used for 2nd and 4th gear. 2nd gear can work even when there are issues with the 4th gear servo apply. BTDT, didn't fully seat the servo cover retaining clip once.
Intermittently lost 4th.

I'll take a look into the servo. I wish I was wrong about the tv cable not being set up properly but I hsve followed guides to install and set up 3 times now, each with the same outcome.
