Thread: Anyone upgraded their auto transmission cooler?

My 8speed runs at around 106degs (moving 6T) on the road pretty much regardless of ext temps.
Is that good? its probably to specs..
Had the trans serviced in Darwin recently and asked the question, (mentioning that weight figure--) and the response was every 80K--
would I still like to add a second cooler like my old BSL? yes.
Is it even possible though??

DPL added a transmission cooler which dropped temperatures by about 15 deg.
FWIW, we also service the auto every 60k KMs.

Forget the trans! Post up some race car pics!!!

Hmm. Mine (also the 8 speed) sits at about 86, regardless of external temps - and that includes a recent high revving trip around Moreton Island on the sand, where I checked it out of interest. Maybe a bit high? I get steady state of oil at about 105-110, trans fluid 80-86, coolant 85-95...
