A500 or 727 trans?.... Need help to identify...

No that is not an overdrive , they have a much thicker pan as the valve body hangs down lower that a 727/904. Also will have a electric connection for the solenoid that controls the overdrive.

blown is right.. an OD trans runs a deep pan..

also a 500 is out of the question anyway.. with that pan it would have to be a 518 if it was an OD trans..
