My 2006 mitsubishi endeavor went into limp mode after it was erraticly going in and out of gear at 65 mph highway. Its slow going into drive and reverse and you hear a rat ta ratta tat as it occasionally slips into gear or violently slips into gear. Anyone experience this. No slippage tho. Does anyone know where i can find what the transmission fliud pressure should be going to the fluid cooler?
