My truck seems to buck around 35-40, if I shift it manually to second its fine, or speed up then come back down, so its in fourth its fine. But while in third gear it bucks. The fluid was changed at 90,000 it shifts smooth and dosent slip in between gears.

Clean/replace the MAF, it's the sensor on the air filter box.
