Probably not too strange, electrical connections and shorts can do some weird stuff. I once got a P0785 in my '33 when on a trip in Palm Desert California, about 2000 miles from home. Just got in it and went to take off and it didn't feel right, was taking off in 2nd and would only shift to 3rd. Not really knowing what to do, I bought a shift solenoid from the dealer and figured I'd put it in, but then it started working fine. Then it did it again. I drove the whole way home with it randomly throwing the code, and when it would, I would get the scanner and clear the code, on the fly no less, to get it to shift into OD. Once I got home it cleared up for a couple of months. I never did put the solenoid in it, but found there was a wire between the PCM and the trans plug that had continuity to ground, until you moved it a bit, then it wouldn't. I ended up running a separate new wire rather than trying to strip the harness in a completed car and haven't had an issue since.
