Hey Jim, I just called it the wrong thing. I did read the TCM, the guy helping me in email said it's the smaller of the 2 boxes so I didn't confuse them. If I read it correctly, the 1 long flash is code 10.

I was told in an email that code 10 is caused by the temperature sensor being bad, it's connector or wires and that this would cause the "lock-up clutch" not to engage. What is a lock-up clutch?
