Been using these B&M cooler for my automatic transmissions cars with aftermarket radiators for years. This is the latest purchase for my personal 2002 Lexus GS300 with a 2JZ-GTE VVTi Turbo engine swap. I am running 6AN lines from the trans to the front of the car, and using 1/2 NPT to -6 adapters to finish off the look and ensure a leak free install.
