My T770 keeps jumping out of high flow. In the mornings when the hydraulic fluid is cold the high flow runs find and than after about 30 minutes is will jump out of high flow and will not go back in. Time after time and i am running a mulcher head. Does anyone know why it keeps jumping out of high flow once the hydraulic warms up. The hydraulic fluid temperature is at only 100-120 when it jumps back to low flow. Low flow will run all day with no problem. The dealer said i need a whole new wiring harness for 6,000.
