Hi.
Did a fluid change on my 2008 722.6. Sent the fluid for analysis purely out of interest.

Results show high Copper and Tin (Bronze). Where are these metals likely to come from? I think i am correct in saying that by 2008 this 722.6 has bearings rather than bushings.

Fluid viscosity was fine at 6.07-@100c (cst) and was described as ' Red, Opaque'.

Anyway, any comments and observations welcome please.

Incidentally, the Transmission is working perfectly.

Thank you.
