1999 DRV 3500 5.9l stalling... TCC problem?
#11
I don't think the computer would have a clue about a sticking solenoid..... I know it looks for an RPM drop when it commands TCC, but, so far as I know, it doesn't monitor whether it disengages or not..... Try this trick..... drive at a steady speed, fast enough that TCC will actually engage...... and then step lightly on the brake while maintaining your speed. RPM should jump about 200 or so.... (do you have a tach??)
