How severe is the problem? As others have said, the TCC was known to surge slightly at the speeds you mention. It wasn't a fault, it's just the way they were. For the most part it was barely noticable, unless you were driving the car and payed careful attention to it.

Back in those days, transmissions were still hydraulicly controlled. So when you hit that magic combination of speed, and throttle opening, the TCC clutch would click in and out. Modern day cars controll the TCC via the computer and it's much better about adding hysteresis to prevent surging.

Next time you notice this surging, very gently place your foot on the brake - not enough to slow down, but enough to disengage the TCC. If the surging stops, then the TCC is most likely what's doing it.

well changed plugs and wires but she still chugs right after she shifts. when you rev her up she sounds good-but when ur sitting at a stoplight and it turns greeen you go to take off and she sputters a little and then goes. any suggestions? TCC possibly?? wheres it at and how do i change?:sad: also the tbi injectors are chattering loudly-is that normal? one in particular seems to possibly have weaker spray.-------also the oxygen sensor on that side is broke-could that cause theses symptoms?
