Well, today was a good news day in my little world.
First, when I pulled the tranny pan, it was shockingly clean. In fact, there was not even fuzz on the magnet. (We has found some tiny fuzzy shavings on the magnet when we serviced the trans pre-race. (It was cleaner than that.)
The fluid did not smell too bad, and was remarkably clean. On top of all that, the stuff that fell out of the valve body was perfectly clean.
Our valve body is on it's way to @88Grandmq for him to work his magic.
Now to just figure out which route we want to go with the cooler.
