Transmission cooler Thermostat?
I just replaced my trans cooler on my 94 325. The new cooler does not have the thermostat installed with it, and the area inside housing where you would install it is sealed off. Do I have to drill this out to make it fit and risk getting metal shavings inside cooler. I took old the thermostat out and put it in water to see when it would start working, the pin starts moving at around 190F. Would it hurt the transmission if I left the thermostat out of the system? Or does anybody know of a good tranmission shop that I could call that deals with BMW's?
