Hi Jeff. My name is***** will be glad to help. If all functions are still strong except for travel then reseal your rotary manifold and also remove and inspect your relief valves in the main control valve for travel for debris, sticking, damaged o rings, etc. 9 out of 10 travel problems on excavators are rotary manifold seals leaking and bypassing pressure internally. Let me know
