oilburner Posted January 17, 2013 Share Posted January 17, 2013 I was told to shift it at 1500 and no more as that is what a Mack likes...I do know that winding it tight gets me nowhere and it goes better at the lower rpms...I still like the quatraplex better...I guess I just need to spend the seat time and figure it out. Oh on more thing...no clutch after its rolling. I don't double clucth either, just use it to pull out. My E7 454 does best at 1600 and 1700, we gross around 88 to 95,000 so i get alot of smoke if i shift any sooner, empty i shift at 14 or 1500, gets her rollin fast.

gry Posted March 31, 2016 Share Posted March 31, 2016 Hey Pal,fix the Eaton,the 8LL,it is far superior to the Mack 10 speed which is an engineering catastrophy,I've got 35 of them and they're all junk. Quote Link to comment Share on other sites More sharing options...

220cummins Posted April 3, 2016 Share Posted April 3, 2016 My experience with this problem has been shifter related in that position. When they pop out of the 1/5 position it's usually worn on the beveled edges of the gears and worn on the sliding clutches. A fuller "tune-up" is needed, replacing the gear, sliding clutch, and re-sealing it. The 310 maxitorque with the LL is pretty nice trans. A 10 fuller is shorter in length compared to an 8LL because the back half is longer for the deeper reduction. Quote Link to comment Share on other sites More sharing options...
