Review on Derale 13102 7000 Transmission Cooler by Brian Cox

Fits my Nissan 4x4 SUV with KA24DE engine. No problems mounting in series after the heatsink. I plan on towing the boat hence the upgrade. I've noticed that my car now won't upshift for the first few minutes of driving in the cold due to the extra cooling. I think that means it works! No problems after warming up. Schedule a transmission flush now in case the installation introduces air into the system.
