The work order say 12Q of syn. oil was used. I guess that means all the oil was flushed out including the TC. I was uneasy about flushing having heard stories. I am told the Tranny filter is just a wire mesh and not the tradditional filter media. I have not seen the 722 trainny filter.
Changing oil without changing the filter to me means an incomplete job. But if this the MB way maybe they know something that am not privy to.

My question is: So should I take it back and let them drain it the "old" way? or simply let it slide and do it "right" the next time.
