It is a transgo gil younger kit for 87 and earlier valve bodys that wont shift to over drive under full throttle. Sucks to be whipping up and a bike and run out of gear because the car wont stay in over drive. If you car falls out of od when at full throttle and wont upshift until you back off to 3/4 you need this valve no matter the year of the car. It was for any 87 and lower transmission that came stock with out it. any questions please ask. i take pp and it is 15 bucks for it think it was 30 or 40 new and is new still.

 

any pics so i can have a better understanding of where it goes, I know what you are talkin about with the shifts though, I also contacted you about the servos.

 

my camera is charging still. It goes in the valve body itself. You have to remove it to install. like a shift kit.
