Transmission cooler Thermostat?

[Laker]

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?

Thanks Paul

The more I studied the oil flow and how this thing works I will need the the thermostat installed. Right now the oil would bypass the cooling fins and not cool the ATF. The new problem I have now is that the old thermostat will not fit in the new cooler. So much for an exact replacement part. It looks just like the oem part and is built in germany but the housing is to big for the old T stat. The oem cooler is made in the USA by Modine corp from Racine Wisconsin.

The blowup on realoem doesn't show a t-stat, I wonder if yours isn't aftermarket.
