Mercedes Benz repair: Transmission slipping 1995 S-500, metal shavings, transmission filter

Question
My transmission slips in 2nd and 3rd gear and partially in 4th gear.  1st and reverse are fine.  I would appreciate some advice on what I should look at.
Thanks, Gary

Answer
I would suggest your k2 and 3 spring may be shot I would first start with the transmission filter and a fluid change, then I would work on the spring repair(s). email me if you have any problems after you have done the tranny flush and fill.Check the tranny fluid also for metal shavings(doubtful)
