Re: Shifting problem
The pwm,,pulse width module,,,,,,pcm ,,pressure control module,,or so called solenoid,,,i'm talking about the same solenoid,,they call it different names.....this control raises and lowers line pressure as the load it sees changes ,,,,,as unit gets higher mileage,,,control seems to leak pressure when trans gets hot,,causing high line pressure,,,or harsh shifts...problem seems to go away when trans is cold...when these shift bangs occur ,,,you can probably hear the pressure regulator in the trans buzzing !!!
this may not be the problem,,,,good place to start,,,may talk to a trans shop about this
