This 700R4 is a 1986 with no aux valve body, it has just been rebuilt. The TV cable is set correct and everything is working great, but it wont downshift to 1st gear. If you take off in O-drive, it goes through the gears great, but when you come to a stop it is stuck in 2nd gear when you take off again. If you manually shift to first it will drop to first gear. I searched on here and found govenor sticking could cause this, but can anybody confirm that this might be the problem? Thanks for any help!
