Re: H2 Bang on Cold Startup?
I had that happen as well. The truck seemed like it would almost lunge with a noise from the engine/drivetrain. Never checked it out, but since I changed the T-Case fluid (Royal Purple) it hasn't happened since (T-Case fluid was 65k old). Not sure if it's just coincidence or not. Been a few months.

No idea, but I get it, too. Anyone?
