Thanks Duxthe1, and everyone...What are the chances? I live on Kauai and good mechanics, parts, just about anything auto is weak over here, especially for Mercedes. I was talking to a musician friend last night and turns out he worked Merzs for 16yrs. He's repaired many of these transmissions and described exactly what you said. Gonna test for anti-freeze and if clean, an easy fix he said. Thanks for the responses...As the world turns...
