I drive a 2007 Jeep Grand Cherokee 3.7 V6 4*2 with the Mercedes-Benz 5G-Tronic transmission.
I tried to shift manually, but nothing will happen. The automatic works great, it's just that I can't manually select the gear anymore. It worked fine until recently, but now it's not possible anymore.
Does anybody have a guess what could be wrong? Maybe a broken fuse or something? I doubt that it is something mechanically.
