  2. Hi there great site. does anyone know why my 12speed grinds in the top two gears up or down but not in the bottom three. split shift or strait shift.truck has close to 500,000 K.M on it. i changed tranny oil there were some fillings in there some small metals to. I have read that these would grind but i don't know if it should grind when you split shift,using the jake helps on the strait shifting. Ithink mack is one of the best trucks around i just don't know about there trannys,but it could just be me to,kind of green on driving truck after 22 year delay.thanks again
