“While merging into highway traffic the truck surged with RPM going to 5,000. Shortly after this event there was a grinding or rattling noise in the transmission bell housing along with unusual shifting behavior and a repeatble vibration + rotational noise between 50 and 60 MPH. The vehicle was brought to the dealer for inspection at least 4 times with claims they could not hear the obvious noise that did not go away. On the last drop off, I picked up the vehicle and the noise was gone but the shifting behavior and the constant vibration from the transmission still persists. …”
