My transmission- 1st shifts into 2nd at 25mph, 2nd into 3rd at 45mph, 3rd into 4th at 55mph. This is not normal. I've replaced the speed sensor, to no avail. Are there other sensors or selinoids that I myself could put in?

Is the check engine light on?

The tps sensor on the throttle body controls the shifts
