My truck runs great no codes present, but after it shifts from 3rd to 4th gear with little pedal input it kinda sputters, only happens in town but if I am running it hard it doesn't happen all. No fluctuations on tachometer, all pids seam normal. How do I tell if it's in the tranny? My scan gauge 2 has no tranny readings. Any help would be appreciated forgot to add if o/d off is on it will not happen at all

If it is the trans the RPMs will fluctuate.

Ok that's what I thought also. How about the torque converter selinoid not working right? Could that be a possibility

That's part of the trans. If the trans were the problem the RPMs would fluctuate. You're looking too far back. The problem is in the engine.
