Silverado SS with RPM level 3 tranny and Circle D 3200 rpm TC, both new. Has kicked P0757 code twice. Search for P0757 issues say to turn off test in tranny diagnostic, but there is no P0757 in tranny test. There is a P0757 in engine diagnostic. Do I turn off there? Is yes or no...off? Not real explanitory.
Help would be appreciated!
