(ERS) Electronic Range Select on my 2010 GC CRD
I need help please ?. When using ERS shift control my transmission does not allow me to limit the highest gear - at 4000 rpm it changes by itself to the next gear ( for example it does not stay in 2nd gear, at 4000 rpm it shifs up to 3rd gear that is 500 rpm before the red line starts ). With my previous 2006 GC CRD, i was able to limit the highest gear. My local dealer say it is for precaution and to save the gearbox. .....cant that settings be changed ?? and if so, who will be able to help ?
