tranny bouncing in and out at slow speeds
Hey guys , I have a 1988 RS, 305TBI, 700R4 as my daily driver. I have started having a prob with the car jerking back and forth as if the tranny is going in and out of gears at cruising speeds (20-40 mph)....... any ideas ???

Next time it acts up, depress and ride the brake pedal slightly.
If it goes away, it's the converter locking and unlocking (hunting).
Could be a bad lockup solenoid or 3-4 pressure switch on the valvebody.
