I've been perusing the threads on Accord V6.com and found a guy who contacted Honda and was told that installing a tranny fluid cooler does NOT void factory warranty as long as the internal cooler is not bypassed. This could be good news for those like me who were hesitant to install one until the warranty was up. Has anyone asked their local Nissan dealership? Anyone on here deal with B&M? Sounds like their supercooler version comes with internal thermostatic bypass to keep fluid within operating temp. specs....Sounds interesting....Thread link is.....HERE

 

Highly recommend the B&M. I tried both a Hayden and the B&M. The tranny behaved better when using the B&M. It warmed up quicker and was more consistent in all driving conditions - I'm sure this was due to the thermostatic effect (actually the B&M regulates viscocity) of maintaining the tranny fluid at the optimal temp/viscocity.
