Mine is an automatic, but I've heard the kit fix is permanent with them. I'm not sure which one to order though. There used to be one and now several and I've heard pros & cons about all of them. My vette shop has never done one but said he needs to know from someone who installed one how long it took, in order to determine the cost. I'm supposed to hear from GM tomorrow when they will want to know total cost of part, install & tow, to possibly approve covering it since I've gone along with them long enough with their dealers.
The first dealer only reprogrammed the computer, admitted it, but GM found they turned in the recall paperwork as though they had done it. GM was not pleased. Next one took one part out and cracked the dash, next one took another part out & damaged the auto rearview mirror/compass connection. Until they start to moniter themselves nothing will change as far as dealers having a bad rep. They either don't care or maybe have not worked on many vettes, but they will never get that experience as long as owners are afraid to let them touch their babies.
