When I last left you I was on my way to my son's shop for a engine/tranny/diff/power steering/cooling fluid change out. First it is always nice to have the right equipment and tools...and in this case expertise (yes he is my son but he is good at his trade

) First the diff... pump out old stuff and fill with Mobile 1 75-90 and rotate wheels to get diff gears etc washing thru new stuff...pump out and repeat...pump out then do final Mobil 1 75-90 with GM posi friction fluid. Tranny...drain and fill with the BMW spec Castrol TWS. Engine oil..drain and fill with Amsoil AMO..oh here is a little tip he does for the top loading oil filters so as to minimize spill etc..punch a hole in the filter top thus allowing remaining oil to drain

Of course while working under car always time for the cell call from his lady

Amsoil syn in the engine with the Bosch filter..

Now to BG power cleaning of the power steering fluid...neat system

Total service of the cooling system including BG ph balancing fluid (interesting test to determine ph etc)

While under the Z took a few pics..
Found the ZF tranny plate

Just a few last views...

Now to results.. a very NOTICEABLE reduction in tranny noise and rear noise...much nicer sound and while we were under the Z found out source of a minor but irratating heat shield rattle..left side CAT shield and we corrected...
Now a few last items and I be ready...
This is fun
