so i was on I95 going about 80 with my auto gen coupe in 4th using the paddle shifters. i guned it and tried to up shift to 5th and the info screen fliped from D to 4. i tried again and the same result. the car was seeming to be stuck in 4th and instead of up shifting to 5th it would just blink a D on the screen and then blink back to 4.

I layed off the gas and coasted a bit and then just shited the gear selector back to D (drive). I felt the car up shift as normal. Then i put the car back into manual and it was in 5th. I was able to downshift and upshift as normal. Since then the car has been runing fine.

Also as a added note about 2 weeks ago I had a intake and bov installed but i believe this is unrelated.

So the question is do you guys think this is a problem or just a computer glitch? I know what limp mode feels like and i dont believe it was in limp mode plus no lights came on.
