Many different theories of the correct Getrag fluid for our SVT. The comment that the trans is the same as the mini cooper is partially correct. The mini uses 2 different manuals and an auto. The cooper-S uses our SVT (285) trans. I believe there is much mis-information about using similar fluids to the mini cooper as the base cooper uses a 252 Getrag.
WD40 has linked a page from his SVT manual that indicates ATF fluid. My 2003 manual makes no mention of that, and I suspect it is not correct.
When comparing the fluid specs, it is apparent that the synchromax type fluids are not the correct spec for this trans. I listed in order below my choices based on similarities with the Ford spec fluid. For the boosted SVT's the second choice of Amsoil Severe Gear is probably pretty safe. For the NA vehicles, looking at saving friction to get the most FE and power leads to the Amsoil Synth Man trans lube. I keep picking the Amsoil based on their website info and the lack of competitors similar comparison data. You can decide for youself, but look at the specs first. The Kinematic viscosity at 40C and 100C show the thickness of the fluids at those temps, lower is better for friction reduction, but unsure of protection. The 4-ball wear is a standard test, with lower is better numbers, some motor oils have .32 ratings. The falex test involved load carrying capacity where higher is better and 2500 appears to be the top area.
The Ford perscribed WSD-M2C200-C (75W90 Gear oil) fluid has specs as follows (from the Ford pubilcation):

As you can see the synchroxxx fluids are substantially thinner than the Ford spec fluid. You may want to seriously reconsider using the synchroxxx fluids in this trans.
Does anyone have specs on other fluids that may be lower in viscosity and within spec for this trans? Always looking to reduce friction and increase HP.
