Thanks for all the Great reply’s
This tranny has 367,000 on it & religiously has filter and fluid done at 25,000 miles during my ownership these past 10yrs.

Tranny fluid is only $20-25.00 cheap insurance for peace of mind, I’m currently making a run of 750 miles a week for the next 4 weeks and just thought about doing a flush or extraction method while changing oil, before the 25000 mile comes up.

I would never consider a power flush like is done a chain stores for these cars

Maybe I’m just being to picky but I Love my Benz and can’t help wondering if theres not another way to take care of Alfred.

You have given me a lot to mull over today as I make my second run today back to STL.
You guys are best
