Mack 7 Speed
in Modern Mack Truck General Discussion
Posted
Hey truckers! Just registered on this site! Glad to be here among all you Mack lovers. Getting ready to purchase my first Mack this week. It's a 2000 RD690S tandem axle dump, with a 16 ft steel body. It has the E7 300 mated to a Maxitourque 7 speed. I am impressed with this ride but the 7 speed has caused some concern for me. She seems to be a bit stubborn even when double clutching. Is she an extended range tranny in so that it should be around 1200 rpm for downshifting and against the peg for upshifting. I am used to an Eaton 8LL. In my trial run with the seven speed I ground the gears alot when I first took off but as my run went on I was getting a little smoother. If you have any tips at all I would truly appreciate your feedback.
