He's talking about adding an external cooler for the transmission. The Pathfinder already has one of these but the fluid goes through the engine radiator first and then through the external transmission cooler. When you do option 1, it just bypasses the engine radiator part and runs the coolant straight through the external cooler. This is probably perfectly adequate and many have done just that with no problems.cabinpath wrote:Thanks for the help guys. I agree. Why wait .... I'll take care of it asap
In regard to option 3 - excuse my limited car knowledge , my mechanic said that he can install this additional smaller radiator that will then only serve the transmission while the original will only serve the cooling fluid... Makes sense ? Anyone heard of it ?
I might give him a call to verify

If you wanted to bypass the radiator permanently, an additional external cooler wouldn't be a bad idea. It probably isn't necessary except in extreme circumstances, but besides adding some additional non-factory fittings into the mix, it probably wouldn't hurt.
I'm a bit anal about leaving things the way the manufacturer designed them, so I replaced the radiator and moved on with everything stock.
