2007 Mazda 3 TCM hard shifting


2007 Mazda 3 TCM hard shifting on this car, I can see on dash board shift light changes after starting speeding forward on (D), it cycles for a few minutes, then sits at (DM), driven at high RPM about 3000 to reach about 50-55 MPH after run for about 30 minutes stop and then go again shifting goes back to normal, (sometimes) it seem like something warm up and make it operate normal.
