E53 3.0D Auto Gearbox Fluid Pressure??
 

Any one know the operating pressure of the fluid in the GM 5L40E auto gearbox??

Looking to fit supplimentary cooler but not sure if the one i have in mind is up to it as it will go to 10Bar but i don't know what the gearbox runs at??

Looking at the pipe connections would suggest it is a high pressure box but youo never can tell????????!!!!!


Anyone know??

TIA
