Default Code-p0700-(tcm)

2008 corvette 76,000 miles:OK guys Wednesday night I pulled into a convenience store and when I was leaving the check engine light came on ,so I pulled over and shut it down then restarted it and the light came back on so I drove it home and it ran and shifted normal. I checked for codes and got a P0700.I got on my computer and read a lot about this code. Auto codes .com gave a few reasons without scanning the TCM.I erased the code and went for a ride and all was normal, now two days later the light has not came back on and still running great.....You guys have any ideal on what to check?. Or was this just another computer glitch...(I Hope)...Thanks...

if there are no other codes present there really is nothing to check.PO700 is code that commands CEL to be illuminated for transmission issues

No other codes,just P0700.I know it has to do with the transmission and the damm dealer will charge $145.00 to scan the TCM with their tool.I've been driving it every day for a few miles and the tranny is working like it should.Thanks anyway..
