TCC

1998 Oldsmobile Achieva

Transmission problem
1998 Oldsmobile Achieva 6 cyl Front Wheel Drive Automatic 135000 miles

1998 oldsmobile, acheiva seemed to be missing between spends 58-70. Replace the plugs and wires, throttle sensor, after more checking I deciede it was the TCC kicking in and out at these speeds, I checked all connections and tighten them. Only one time did I get a code and it said loose connection. I also changed fluid and filter in transmission. I can put it in drive and runs fine, seems to be only in overdrive when this jerking happens. Do you have any suggestions of what I should check.
Thanks
