Diagnosing, Adjusting and Fine Tuning Mercedes Automatic Transmissions
High Mileage and age can raise havoc on the shifting patterns of an automatic transmission. Even if the fluid has been changed on a regular basis, they still wear out. Seals harden and leak both internally and externally. Vaccum and cable shift controls leak and fail. Rubber hose connections crack and work loose. And quite often some mechanic gets in there and messes things up.
