Hi,
Just after some ideas and where to head next. Machine background: transmission oil level is correct, t/c inlet pressure and outlet pressure and lock up clutch pressure is within specifications. Transmission modulation pressures are within specifications. Engine coolant level is correct. Did a stall test and the temperature of oil line coming out of t/c is starts at 70 degrees Celsius and rapidly climbs to above 130 degrees Celsius. When the stall condition is removed and engine is free- revved to cool temperature down it drops quite quickly. Seems to be a max of 30 degree celcius max temperature drop across the powertrain oil cooler. T/c is at 59% life. Dont have any oil sampling results.
Thanks in advance.
