Park?At this time, even when you put it in "park" it still rolls. I just had the transmission replaced and that did not fix the problem.
So you bought this truck in this condition then?This is an Allison transmission. The shift lever says - PB. I have been told this activates the "parking brake", but is not actually in "park". My son-in-law has been trying to get a scamatic so he can do the work on it. But right now, nothing has been done on it.
