PHOTO DIY- 722.6X TRANSMISSION FLUID CHANGE

Greets,

As I have posted in the past, DB has changed their mantra about the "sealed for life concept", on the new vehicles which have the 722.6X transmission.

Not to re-hash an old topic of "change or don't change", but this post is just meant for those who DO believe in changing the fluid. My target has always been 40,000 mile intervals.

I AM IN NO WAY PROMOTING GOING AGAINST WHAT IS IN YOUR OWNERS' MANUAL. YOU DO WHATEVER THE SPIRIT LEADS YOU. YOU MUST CONSIDER THE POSSIBLE REPERCUSSIONS SUCH AS WARRANTY VOID, ETC.

ONE NOTABLE THING ABOUT THIS PROCEDURE IS THE STRICT ADHERENCE TO "SURGICAL-LIKE" CLEANLINESS AT ALL STEPS, AND METICULOUS CARE TO NOT OVER OR UNDER-FILL THE TRANSMISSION. APPARENTLY, THESE BOXES ARE VERY SENSITIVE TO ANY DEGREE OF CONTAMINATION OR IMBALANCED FLUID LEVELS. IF YOU OVERFILL, YOU NEED TO SIPHON OUT EXCESS.

I opted for the "new" type fluid, designed for the new 7-Speed boxes. I had a long discussion with one of the engineers at MotherShip Montvale, who confirmed that the use of the "New" fluid- A.001.989.45.03.10 (which is also only 1/2 the cost of the "old" fluid A.001.989.21.03.10) IS ALLOWED!!

The usual CYA blah, blah stuff. I am not claiming any expertise. I make no bones about it, I am a novice mechanic. My projects are based on my interpretation of the WIS procedures, and/or outside sources. Do work at your own discretion.
