  1. I try to shift smooth too but I still have problems some times ! I tried with the rpm, I tried with the sound of the engine and still sometimes grr grr on some speed especialy from 10 to 11 and 11 to 12 , goes better when loaded .

    I have a Mack 12 speed with an E7-400 1990 , will I stop driving cause of the grrr = no do I want to improve yes !

    do I try to improve = yes , the boss ( me ) is not always happy about that ! lol

  2. nothing wrong with a Mack 10 spd, the gear steps in the 10 actually make it easier to drive loaded in high range than an 8LL, I like the Mack 10's I have driven I had one straight 10 and a 310M multi speed reverse that one was nice in a dump truck you could shift all thru low range in reverse to get the perfect gear. I dont think it would be a great idea to swap it out but the reason is you could have that one fixed in a day for less than what it would cost to get the parts and the driveshaft done to swap em out.

    Sorry I meant a Fuller 10 speed not a Mack one I did missread the post properly . I do have a 12 speed mack and she is good to me.
