Beercanman Posted September 2, 2008 Share Posted September 2, 2008 Hey guys I need a little help. I have an 05 Granite tri-axle with 370 hp motor, and Mack 10 speed with just over 127000 miles on it. Had trans rebuilt 2 months ago because hi-low syncronizer came apart. Last week it started loosing coolant but couldn't find where at first. This morning I started truck after sitting for the long weekend, and the engine shutdown light and buzzer were going off. Checked it out and it took 4 gallons of coolant. Started it up again and noticed alot of fluid pouring out to the ground. It looks like oil and water mixed, comming out of the top of the trans just to the right of the base of the shift lever. Anyone have an idea whats causing this and how bad it might be??Thanks for any help.
