Question

Getting a code p0720 just replaced 3rd clutch pressure switch

Answer 1

P0720 Problem in counter shaft speed sensor

The countershaft speed sensor is a generator pulse sensor, if the pulse drop out due to a open condition or a short to ground at the countershaft speed sensor you get this code. As long as there is no P0730 which is a shift control code, the speed sensor would just be a faulty sensor.
