I guess issues with the 2120 are well documented. My local dealer has one as a trade on the lot. When I inquired about how much. They responded $4999. I almost fainted (especially compared to what I paid for my G2160. When they saw the look on my face, they offered that they did have to install a whole new transmission in it. Guy on another forum who works at a dealer said it's not "if" they fail but "when". Also indicated the only real fix is to install a newer updated one. Good luck on it
