Overdrive Indicator Flashing
So last night I blew out what I believe is a coolant return hose the little 90 degree one on the back side of the head just above the EGR Plate. after the hose blew out my O/D OFF indicator started flashing while the overdrive was on. It doesn't flash at all when the vehicle isn't moving weather its in park or drive. And it stays lit when the overdrive is actually off. The over drive its self still functions properly so my guess is there is a connector around the bell housing that got wet or I might have accidentally disconnected something. Have any ideas?

A flashing "O/D" light is an indication of an auto transmission trouble code. I don't remember the exact procedure on how to check it, but it should be in the TSRM, as well as a description of said codes

Try again.... those aren't transmission diagnostic codes. Did you follow the link I posted?
As for the code 11 and/or 22: What good will it do to ignore the ECU codes? Something IS ovbiously wrong or they wouldn't be present. You may reset them to see if they're old codes for things which may have been fixed in the past but it's not too likely.

TSRM says 22 is the CTS and 11 does not exist (not listed as a code). Don't know what source you checked from but the TSRM is the one to use... But you need to check the trans codes as per cre's link anyhow.
I'd lay odds on a speed sensor fault (42 or 61) as it only occurs when moving. Perhaps the wiring plug got wet or knocked loose but the code will at least give you an idea where to look closer
