Follow the good advice here: Change the ATF fluid completely (trans drain and torque converter) and the filter and gasket. Use MBZ parts!

Adjust you vacuum modulator. Check for vacuum leaks.

I have been using synthetic ATF (Mobil 1) in all the cars and it works great.

If the trans has been properly serviced you shouldn't have to touch the valve body at all.

Keep us posted,
