Question about 1993 Buick LeSabre
When going down the road the transmission wont kick in like it is suppose to it has new transmission fluid and filter and it is full.
When you say kick in do you mean shift? the throttle valve cable controls the "shift point" of the tranny if you mean it shifts at higher rpm's then it should and the modulator valve controls the "softness" of the shift if it shifts weak or too hard id replace it. its a 20 dollar part so if not the problem wont hurt your wallet too much

Try running a trany flush machine on it at first and if that doesn't work you may have a bad tork converter clutch.
