oilburner Posted October 8, 2012 Author Share Posted October 8, 2012 Has no one ever ran one of the 13 speed macks before, i was just wordering if it was a sign of trouble to come or if they are like the eaton 13 and 18 speeds, they have a slight wine in the overdrive position.

turckster Posted October 9, 2012 Share Posted October 9, 2012 I don't think a whine noise is normal for any transmission. There may be some damage on the gear(s) like some slight pulling/galling of metal on the gear teeth. Most likely cause is the EP additive breakdown in the oil(not changing oil at recommended intervals) or overheating of the tranny. The noise will probably get worse with time depending on damage.

David Posted October 9, 2012 Share Posted October 9, 2012 A noise from the rears can be transmitted to the trans. You wouldn't be the first to get into into the trans and later find a chipped ring or pinion.

oilburner Posted October 10, 2012 Author Share Posted October 10, 2012 Well i was afarid it my be bad news, it is like a high pitch wine, Now most eaton fullers 13 and 18 speed make a similer noise in the rear box mostly the 1400 series but only in the overdrive postion at mid range in the rpms, but this one does it in the underdrive postion at any speed and it gets louder with engine speed, shift it in direct and it is quit as a mouse, i thank i will change the fluid in it this weekend and service the truck it needs a good greasing anyway. I am starting to like the transmission i hop it is not nothing major, does anyone know what oil to put back in it, or what it calls for, it is a 98 model T2130.
