AutoZone's crappy little scanner won't read transmission codes.
After I convinced the dope that was working at my local store that the flashing O/D light meant there were transmission codes stored, he came out and scanned it for me. I watched to make sure he didn't pull a fast one on me, but the little orange reader they use showed no codes, despite the fact that my EEC was saying otherwise. Later on I scanned it myself with a Ford NGS reader and it showed trans over-temp and also a code for exceeding the rev limit.
Maybe the XCal 2 will read it? Know anybody that has one?
