Auto serviced 2010 SDV6 3.0
Trannie bloke suggested replacing heat exchanger as my fliud had trace coolant <10ppm
Any of these fail?
Mine saved in time he says?

Price for LG6 @ MR Automotive yesterday = $26/L
Also, can anyone get me about 100ml of clean new LG6? I want to get a lab analysis done.
Can save you the effort if you like:Quote:

Interesting sodium and potassium levels for a virgin sample Shane.
The potasium levels are fairly consistant with the used samples. Sodium is elevated in the used samples compared to the new sample.
For the record, the sample on the far right was the from the first change I done on the transmission. The second from the right was sampled at the time of failure

It always makes for interesting reading when you have a failure.
Doesn't help the hip pocket nerve though.
Good to know that sodium is there from the start, otherwise you'd be looking for a coolant leak. Elevated sodium may indicate that.
Any conjecture from your trans shop or ZF as to why it failed?
II didn't get any offical report, but the original trans shop was going to rebuild it until they stripped it down and they decided that it would be more beneficial to have ZF rebuild and test it. The guys mentioned that the clutch packs where completely stuffed but from the initial noises that I had I would suspect a bearing let go
I have a XR8 FALCON with the same transmission and they have a recall for the radiator & cooling pipes. I have bypassed the radiator on mine because of the horror stories about coolant contamination of the fluid. The 6cyl falcons have the same type of heat exchanger as yours and they fail also, in fact a lot of taxi owners replace them between 60000km - 100000km. pwr sell a heavy duty one for the fords so might make one for you. just make sure your sitting down when you get a price.Quote:

Just havent heard of D4 having this issue or 95% of other makes and models...
Every modern car seems to have these brazed plate heatexchangers nowadays!
At over $300 for the unit I hope they’re not common to fail [emoji53]Quote:
