Cant figure this one out and I have no codes. Everything works fine with the exception of 2-3 shifts. Well, even those shifts are good and firm, but, they are confused.

Example: Coming from dead stop at normal acceleration, the shift from 1st to 2nd is normal. Before it goes to 3rd, I push the pedal down to where it should hold in 2nd....and it still upshifts into 3rd. Now, if I let off the gas slightly, it will downshift back to 2nd. It will also downshift if I put it to the floor. Its like it is fighting between those two gears. It also does not seem to do this when the trans is cold.....only after it has been warmed up for 15-20 minutes or so.
