Recent problem after tuning

I just had my car tuned by a local tuner and after I got it back, the reverse lockout on the transmission of my Mn6 no longer works? WHile driving and wanting to shift to 5th gear I now have to be very careful not to "grind" going into reverse. This was not a problem at all before the tune. The guy was using HP tuners. I want to know if it is possible if he accidentally changed something in the program. He says it is nothing he did and it was just bad timing. I hooked up a "EASE SCan"
program and it says it is working, but I don't know if the the MPH engaement is right. I know it supposed to make the solenoid "lock-out" after the car starts moving a couple of miles an hour, but I can't tell if that was changed?

Thanks for any help.

Have you reseated the connector? When I first had GM fix my rear end and it was doing that, that's what they ended up doiing.

Good luck with that buddy...

Unlikely it is tune related--Probably the only thing he may have tuned on your M6 was the "skip shift" feature
It may be speedo related however--did he tune for aftermarket tire size ??
