It's 600SEL 1992. I was having a slipping problem from the 2nd to the 3rd so I replaced the whole transmission with one imported from Japan. When I installed it it worked perfect, even I noticed more HP. After about one week on using it I made a kick-down so the transmission down-shifted to the 1st, after that I noticed slipping from the 2nd gear to the 3rd gear. Then after 1 more week the slipping problem disappeared and will occasionally comeback again. What could cause such a problem?
