Everything fine till this morning. Shifts fine until it's time for the last gear to shift (overdrive) - nothing - stays stuck in 4th, or 5th - didn't count the shifts. At about 45mph I'm turning 3k on the tack. Fluid is fine, red, smells good. Interesting thing is that the "D"indicator light (on the dash) is not coming on when shifting through the gears. Don't know if there is a connection between this and the lacking shift.
