The sensitivity of the Torque Converter to Glycol contamination was due to
the materiel fabrication, mild steel.
The temperarure at which to dip the box was 80 deg' C, the fill level is half way between min & max on the stick.
The oil temp' may be checked by using a thermistor lowered down the dipstick
fill tube.
The viscosity of the ATF dose not change with temperature, as viscosity is
merely the relationship or graphicaly the curve where one axis shows temp' &
the other pour rate. ( Pour Rate = flow of a given volume of a liquid through a
given orifice, time taken being the variable).
Antifreeze lowers the freezing point of the coolant, it cannot therefore raise the boiling point as well. Pressurizing the system does that.
The level quoted in the TSB posted on this thread indecated a box failure point of 300 mg of contaminant per Litre. One litre of genuine MB ATF ( MB recognise Televisions Pt' no') weighs 0.870 Kg.
This I believe as a percentage by weight works out to approx' 3.5%
I have to say that this seems very arbitary considering the issue's at stake.
As a hopefully intelligent customer if I had made this sort of investment say
£30-£40k in a Merc' I would expect a comprehensive detailed dialogue and assurance from the dealer.
