[ChinaClipper]

Been look for a solution to PS Fluid For my 87 190D. ATF is listed pre 86..A friend replaced his fluid with a Febi product and with in 2 weeks, it was leaking. Disassembled the pump and all the rubber was harder than a woodpeckers lips. Pentosin keeps popping up as a replacement. Going to start this process this week, any suggestions? Btw I searched and most of the info was very old.
