Got the Davies Craig 678 Transmission cooler with a fan fitted in last week. Tin's bracket worked a treat.
Fan is yet to be wired but the transmission temp difference is great... I'm seeing 10°C - 20°C less than usual.
Normal driving temp is sitting around 68°C. Highest so far has been 94°C going up to Sky High Mt Dandenong driving in D to test it out.
