I have a project that I've just got running and registered running and LS3 and 6L80E.



When it's idling it tries tries to drive the vehicle forward moreso than any auto I've ever driven.

I'm suspecting the cooler lines are too small or the cooler in the radiator is restricting the oil flow and loading the trans up.

Once up and moving it goes quite well adn drives OK.

What are people's thoughts?
