You either have a hydrulic fluid pump problem or you have overtuned it to such an extent the air cooling of the lower intercoolers is causing the fluids to overheat.

pretty sure it is not the pump prob, cuz i just send it to the dealer and get checked. they did open it up and clean the mess for testing, but it keep on going. they say could cuz by tuning and get over heated.
