I would as a final if it works, do a proper fluid level check and correct as required via the actual level tube in the transmission pan.

This I am not sure about ... but if the flow from an old R50 Pathfinder is any indication .. those pumps are powerful. It would spit out 2 quarts in about 12 seconds. It appeared to me to have more than enough power to suck fluid up. But that is just a guess in my head.

I would do this with no less than 11 liters in the "clean"bucket, since this is the max capacity of the system without the cooler. From past experience with other vehicles I think the whole thing will take less than 1-2 minutes. You would certainly want someone in the vehicle to turn it off on queue. Obviously a small amount of new fluid would be wasted in the old bucket as that's the indicator that it has flushed it all. This method does certainly flush the torque converter.

I should be able to try it next weekend. I've got $250 worth of tranny fluid on its way. That stuff isn't cheap.

My fluid will be here by Saturday, so I am going to give this a shot. I also have an 24Mx1.5 fitting coming as well; to top off if need be. Does anyone know for sure if it's the upper or lower hose that is outbound/inbound from the cooler?

Thanks.

I think that's a matter of opinion. VW claims never, I would say 40,000-60,000 miles. Closer to 40k if your towing, lot's of stop n' go or unusually hard on it. Closer to 60k if it lives a fairly highway bound easy life.

40K if towing something heavy for a lot of the time, 60K if not, and don't take the slightest bit of notice of VW dealers telling you it is sealed for life.
