how is the fluid?

Customer: replied 1 year ago.
I apologize, I didn't send my entire question. The fluid levels are fine. The minute I shut the car off and restart it totally stops. I had noticed leaks in the ATF pan and replaced the gasket. but the problem persists. It completly ceases once the car has been turned off and then restarted.

any codes?

Customer: replied 1 year ago.
I had the codes read a while back but i lost what i wrote down. I know it is reading o2 sensor problems, and it registered that the transmission was slipping.
