I have a 700hr t190 (2005) with selectable joystick, and while one of my operators was running it the right track in REVERSE ONLY went to about half power and half speed! it will not back up in a straight line unless you feather and slow the left track....... it does NOT make a difference if it is in "H" pattern or "ISO" patternn Is there any sort of calibration procedure that can be done in the field ? does anyone know which coil operates the right reverse ? does anyone have ANY ideas ? lol..

is it throwing any fault codes? that sounds like a speed sensor to me. you could check the wiring harness to the pump controllers for any damaged wires, it's hard to get to the speed sensor wiring to check anything. bobcat has an update for SJC machine to disable the speed sensors with new software. :drinkup
