Hey together! With my new builder tipper TGS 33,480 I occasionally have the problem that the switching support fails, i.e. I stand in the middle of the intersection and don’t come away anymore, because without raw force no more gear goes in. Also the split group doesn’t like then. Vehicle WITHOUT Comfort Shift! What can this be? Vehicle has now 12000 down and is three months old, with the friendly one is guessless and has already exchanged various controls, so far without success. tt only sporadically on, and almost always with the yellow message KUPPLUNG! on the display, whereby the then but clean separates, because I can switch on side drive cleanly.
