Question
rondefly
I have a 2001 Mack Vision 450 HP the jake has a two position sw and while I am loaded (approx 75000 lbs) going down a 6% hill I have to be in 3rd or 4th low range to hold it back, My question is: is it just not working well or should it be more effective. everyone else is passing me by while I am down to about 15 or 20 MPH.
Thanks
Ron Triano
