I thank everyone for your comments on the LBZ model of the Duramax. I found an early 2007 GMC Sierra Classic with the LBZ engine in it and the truck was in very good condition. I drove the 830 miles from Tennessee to Houston, TX to get it and was pleased that it got 22mpg on the way back to TN by me keeping it under 70 most of the time. About 150 miles of that was in severe rain and wind in the left over effects of the storm that hit Oklahoma City.
I noticed that it does not lock into 6th gear until it gets to about 62 MPH. Will it be a problem to tow my 14,000 lb 5th wheel in 6th gear out on the open road, or do I need to keep it in 5th gear manually?
Thanks for your comments.
I would just leave it in D, tow haul engaged, and let it do its thing. As long as it isn't hunting between 5 and 6 (which is probably wont), there should be no issue.
Actually, I would set the cruise at 64, let it shift into 6th, and enjoy moving along at 1700 rpms!
Good luck!
Agree. Too many guys think they are smarter than the Allison...LOL. Just put it in D with Tow/Haul engaged and let it do its thing.
