It is the same, except slightly thicker.you can do this in your garage, on the floor. I removed the passenger front wheel, and jacked up the car.Here is the ZF heat exchanger. People have been reporting failures, meaning they notice their coolant overflow bottle getting sludgy with oil, which also means the gearbox gets coolant in it. For $196 (retail) you can buy the bigger version or $139 for the stock one. Or you can wait until it fails and rebuild your gearbox and replace it then. My car is now 4 years old and has 50,000kms so I'd rather do it now for peace of mind.Uploaded with ImageShack.usConnecting to the heat exchanger is a "coolant junction", which I think is called a Bypass Valve. These have been superseded because they leak.Mine leaks.Uploaded with ImageShack.usThe part that has replaced the black plastic junction is a one piece pipe, with two new hoses.I'm going to use a hoist to swap the new pipe work in, and hope like hell I don't have to remove the inlet manifold.To swap the heat exchanger is straight forward, the coolant hoses have hose clamps, and the ZF lines have push-pull connectors.There are two bolts to remove and that's it.Here is the new one in.

The same chance of getting the two fluids mixed is there or is this new one a lot better in that regard? A few guys have just the external coolers set up with good results, totally eliminating the possibility of coolant and trans fluid mixing. Link to comment Share on other sites More sharing options...

I keeps the trans nice and cool, the highest temp I've seen is 90c and that was at QR. Link to comment Share on other sites More sharing options...
