Yeah, I hear ya! I'd love to see what is does too! I never did crack open the secondaries since we had the trunk full of tools, fluids, water in a lidded bucket, floor jack and jack stands, so was mindful of those flying around the trunk. It was sooo tempting, but I played the cautious card. The TH400 shifts so quickly that it's in high gear by 20 mph. I thought it lost 3rd gear early in the drive, but it was already there and confirmed with a manual downshift. Overdrive would be nice for sure.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.

Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
