Hello everyone,

I am in the market for an 2010-2011 E350.

I have a couple questions.

The 722.9/NAG-2 transmission known for breaking the transmission oil pump. MB released a updated version of this pump with a needle bearing in place of a bushing.

I have been a trans tech for 35 years. I have been looking and cant seem to find the year that MB switched from the bushing style pump to the bearing style.

Please advise,

Mark
