:confused: at what speeds should my 1990 supercoupe shift at,, when im on it, it shifts into third at 2500 rpms. its too low, isnt it, it doent get any boost then and the take off is horrible. what should it be at .. ????
 
Don't really know when it should shift but maybe your throttle position sensor is bad? I have a GM that shifted crappie until I replaced that sensor; works like a champ now, don't know if that’s how our AUTO SCs work but thought I would throw that out there.
 
Throttle Valve Cable

Welcome.

Another thing to check would be your TV Cable.
Sometimes the plastic adjuster (factory f-up) just slips a little, and sometimes the grommit that attaches it to the TB linkage wears a little and you get less of a pull on the TV Cable as a result. This means its time to replace that part if that's actually happening. You don't want that to pop off there while you're driving it!
I heard either on this board or TCCoA of a metallic replacement that's supposed to be superior..:cool:
