When cold goes thru all gears just fine, when it warms up no 4th or 5 gear. Oil not burnt and look good too, no codes. Changedo oil same result. If it will go into 4th or 5 get a very bad shutter from transmission when trying to accelerate unless I put it to the floor then it down shifts but will do it again when up shifts. It's a 2010 with 100 k on it. Never tow anything just normal hiway driving.
