Update Time!

My Dealership opened my Transmission and installed the so called

"6th Gear Service Kit" #30099AA840

and changed both gear wheels.

Result

The whine in 6th is completely gone!

The onyl part-difference we noticed was a better surface finish of the new gear-wheels in comparison to the old ones.

The only whistle noise left is from my 4,44 rear diff.
