It could be the transmission. It could also need a tune-up. Is the bucking and shaking the result of misfire? Find someone with an engine analyzer and see if there is a miss.(s). Normally if there is a miss in a couple of cylinders it shows up under load. Process of elimination. Check the easy things first.
