Terry's been talking about the MTL issues with a couple chemical engineers on the other side of the pond that know a hell of a lot more than the ppl on this board. Here is one recent email.

Dear Terry,

You're right about non-ferrous
(brass/bronze,aluminium) corrosive wear with EP
additives. Those based on sulfur/phosphorus are not
suited to European Ford transmissions due to increased
corrosive wear/glazing on these materials. The EP
additives used in the WSD-M2C200-C series are
developed from ATF packages (zinc/sulfur) and provide
good EP performance without causing this problem.

The viscometrics of WSD-M2C200-C are significantly
different from typical 75W90 lubes and have much
better low-temperature viscosity. Running a typical
75W90 material will certainly lead to baulking at low
temperature.

Unless the Redline fluid was specifically designed with
the above characteristics I would recommend you switch
back to the FCSD 200-C lube. Never use GL5 as you can
only achieve this level with sulfur/phosphorus EP
additives.
