I've just been alerted to a potential problem with the 6psd heat exchangers that are mounted on the block in the Territory's and Falcons. In the BA/SX the transmission had cooling lines into the radiator which ruptured stuffing up the gearboxes. In the SY/BF the transmission cooling lines did not go to the radiator but to a separate heat exchanger on the side of the block where coolant was piped to the exchanger. I imagine this was in an effort to stop the corrosion problem that happened with the radiator systems and it would have worked except for the fact that they corrode and do exactly the same as the earlier radiator cooling lines. So my thoughts are to fit an air/oil cooling system in front of the radiator and totally bypass the ticking time bomb which is the transmission heat exchanger.
I'm looking at this kit.
Now I do know that the ZF is very sensitive to line pressure variation and if it outside certain parameters the ECU will put it into limp home mode. My question is, has anyone fitted a full bypass cooler to the ZF and if so how did it go? Was it the system above?
Am interested to hear from anyone regarding this issue, as it is just a matter of time before my blows and destroys my gearbox. If I fit the bypass I've totally fixed the issue. If it messes with the ZF's head I'm in trouble as well. At the end of the day though I DO NOT want water in my ZF.
