Just started acting up a couple days ago. The tranny upshifts fine. Only when it downshifts into 4th gear it slams into it. Every other gear downshifting is fine. I know its 4th because I put it into manual mode and watched it downshift and when it hits 4th it slams down. Even in manual mode when I shift to 4th it slams. I am bringing it to dealership before my warrant runs out. Time to put stock intake back in lol

Wait...did you plug back in all the intake sensors? Make sure, because leaving the IAT sensor disconnected makes the PCM jack up the transmission pressure.

Yes I never unplugged anything. I installed intake tubing pre maf so everything above is still stock. The past 3 weeks the tranny has been acting fine so im not sure now.
