if a temperature sensor pictogram is lit it should have a symbol indicating hydraulic or drive, the icon should look like a drive gear or for hydraulic it will have a drop like fluid in it. Which ever one is lit you should check that temp circuit. check on the motor itself for a temperature sensor, if no temp sensor is mounted on the motor itself then the problem is indicating that the motor controller for that system is getting hot. also double check the sensor wiring going into the motors, there are 4 wires, 2 are for temp sensing and the other 2 are for brush wear indicators, if all that checks ok then check the motor controller's temperature using a diagnostic temp gun and see how hot it is really getting. If the controller is at normal temp then you still have issues in the circuitry, possibly in the logic card.
