Aftermarket ATF oil Cooler
Hi All
I plan DIY to install the aftermarket atf oil cooler & my concern is should we keep the stock thermostat or bypass it.
Regards
Omar

I'm pretty sure that your oil does not have a thermostate. The thermostat controls your water temperature and you should mess with that.
BMW engines do not like to get hot as the are aluminium blocks and heads.
Its fine to play with an extra oil cooler but always have a good working water thermostate in your car

The heat exchanger has a thermostat I understand (the one on my 530d does).
Its designed to regulate the ATF temperature so you need to be careful. Too cool might be as bad as too hot. Maybe it's there for German winters to keep the temperature up rather than down.
One reason to bypass could be to avoid the ZF milkshake - but without temp regulation it might behave strangely - viscosity issues?
Maybe install a temperature first so you can quantify the temperature.
