Eddie Posted August 30, 2009 Share Posted August 30, 2009 Hi Guys, Can you tell me which pipe from the gearbox is which, ( which one takes the hot oil to the cooler and which is the return) 1 pipe comes out of the side of the gearbox the other from the bottom, Also which one has the temperature warning lamp in it? Thanks Eddie Quote Link to comment Share on other sites More sharing options...
steve_d Posted August 31, 2009 Share Posted August 31, 2009 I don't have the answer but can predict that those who do will want to know which gearbox, vehicle and age as the pipework is most likely different for each 'box. Steve Quote Link to comment Share on other sites More sharing options...
Dave W Posted August 31, 2009 Share Posted August 31, 2009 Assuming it's a ZF auto, the answer isn't completely straight forward... The oil cooler is in line with the torque convertor so in normal operation the oil flowing out of the torque convertor goes to the oil cooler and then returns to the valve block. IIRC the output in this case is the one on the side of the box with the return to the one under the box. (This is from memory though !). The problem with your question is that, when the gearbox locks the torque convertor it does so by reversing the oil flow through the torque convertor which also means the flow through the oil cooler changes direction at the same time. The short answer is therefore, that depends The temperature sensor is normally located on the end of the oil cooler and, as above, can be on the input or the output of the cooler depending on the direction of flow at the time...

Eddie Posted September 2, 2009 Author Share Posted September 2, 2009 Sorry, Yes it was a ZF from a RRC - didn't realise the oil was pumped both ways, All sorted now thanks for the info. Eddie Quote Link to comment Share on other sites More sharing options...
