I know I'll get hammered for this but what fluid is best for Allison trans. I have a 03 2500hd with 245,000 on it. . I'm putting a ppe pan on it and just wondering if there is a fluid recommended for it. Any help is much appreciated.
I've had the issue. If I park with front of truck high than back. It loses it prime. A few pumps on primer and it works. while pumping primer I see bubble coming the red wire boot. Any ideas
