Caterpillar has changed the control lever 4 times and the latest version will not work on a 416C. Run out of options with my dealer, and can't move the machine.
Why four times? Specifically, what fault was found each time? Also, machine serial number, and component part number, will yield better help from here. What is it, a 1WR?
Do you mean that the Part Number of the transmission control lever has been changed 4 times by Caterpillar.?
