93 tranny not shifting properly

I have a 93 grand am with a 2.3 automatic tranny. driving around town runs great, take it on the highway and come to a stop, idles good, try to go and she stalls. If you are doing 100 kmph and slow down to 50kmph and then start to speed up the tranny didn't shift down on it's own there for your rpm's are so low you can't get going again unless you manually down shift. Whats' up? I am thinking either tcc sensor (no engine light on) or change fluid and filter.

Re: 93 tranny not shifting properly

yeah, several things possible,

Throttle valve cable needs adjust
Vacuum Modulator
Neutral/Park Position switch
Clogged trans. filter

Hoo boy, could be most anything. Best to have a shop look at it, save you some aggravation with self-diagnosing, at least, my thinking.
