84 3.8L Bucks in 1st gear at low speed May 04, 2016, 07:31:25 PM Hey, have a 1984 Tbird, and have noticed a few times that while at low speed, in first gear, on a grade, driveline will buck a bit. Has not happened in other gears. For example, was in parking garage, and going up a grade at 5mph and noticed the bucking. Any thoughts on this? Seems to be tranny/driveline and not engine. Could this be band slipping?Thanks.Russ Quote Selected
