I have a 2009 chevy cobalt LT 2.2L with the 4T45E transmission the problem I was having it wasn't shifting into 4th gear. I checked fluid was fine so I changed all of the shift solenoids and computer inside the transmission. The 2-3 shift was burnt up. So I fixed that but since I've changed them and put new fluid and filter now my car shifts hard only when it's hot. I live in texas. So on days it's 30ish outside car drives fine until the motor and transmission heat up to running temp. Once I drive for a while it's starts to shift early like into 4th gear before I hit 35mph so it bogs the motor way way down. And when I'm on the freeway doing 75mph and I need to get up and go it won't down shift when the motor is warm. But when it's cold I can be doing 75 and 80 and will downshift and go as normal. There's no check transmission light on.
