Hello guys I was wondering what could be my problem... I have a 1993 sierra 1500 single cab 4.3l automatic and my problem is when I shift into gear from parking into first the truck jerks forward and when it goes from 1st to 2nd also a jerk and after that I have no problem ... Some one told me that the drive shift could be too loose on the knuckle but I don't know what the problem could be ... Some please help thanks.
