On start up the car will shift gears but after it gets warmed up it doesn't shift and the check engine light comes on. Not low on fluid.

Let's start with codes. This sounds like a shift solenoid issue but we need to see what codes it is throwing before we go any further. That will tell us what the potential issue is or at least the system.

If you cannot pull codes then just stop by a parts store as most of them offer a free service of pulling codes. Clearly they want to sell you the parts that you will need which is why they do it but we need to start with the code and then do some diagnostic work to figure it out. Thanks
