Symptom: a Honda Accord 2.2 into the factory maintenance, the performance of the cold automatic gearbox everything is normal; and when the temperature rises to normal, the way in the brakes on the brakes, the engine jitter abnormalities, and even car. This car was burned six months ago, automatic transmission friction plate, after the failure, had to repair a few repair shops, but also replaced some parts, but did not completely solve.
    Fault check: In view of the above phenomenon, we on the car's braking system, the engine was a comprehensive inspection and maintenance, excluding the relevant doubt, check the end of the automatic transmission to check, automatic transmission itself is no problem, The oil temperature in the automatic transmission is abnormally high. Since the automatic gearbox has been inspected and no problems have been identified, it begins to consider how to eliminate the high temperature of the automatic transmission. What causes the gearbox oil temperature too high? It is speculated that it may be a cooling system. Because this car automatic transmission is by the tank cooling. So, remove the radiator, blowing the automatic transmission heat pipe, found to be blocked, and then with high pressure gas blowing, blowing a lot of dirt, until the heat pipe completely flow. We suspect that the dirt may be the residue of the ablation plate. Finally on the road test, the phenomenon of failure to eliminate all normal.
