    I am looking at installing a transmission cooler to completely bypass the factory tarnsmission cooler that is built in to the radiator as a preventative measure. The - Nissan Pathfinders have had issues with the radiator leaking and the radiator coolant being mixed with the transimission oil and destroying the transmission. Is this advisible, would I need to install a sperate thermostat and what size would I need since I am compeletly bypassing the factory cooler.

    It is possible to install a transmission cooler and bypass the factory transmission cooler on your Nissan Pathfinder. This is not recommended by manufacturers, but it is possible.

    You will want to get the largest transmission cooler that will fit your vehicle. I do not know the area that you have available to install a transmission cooler, but if it will fit, I would recommend the Derale Series Plate-Fin Transmission Cooler Kit, part D Measure the height, width and depth of the area where you want to mount the transmission cooler and those dimensions will help you select the appropriate size cooler.

    The best place to mount the transmission cooler is between the AC condenser and the grill. You will first want to cut off the transmission lines going to and from the radiator.

    It is very important that you plug the lines you cut coming from the radiator because you do not want the radiator coolant leaking out. You can then attach the a rubber hose to each transmission line and run those to the inlets on the new transmission cooler. I have attached two images showing how the hoses and lines attach to bypass the radiator and the preferred mounting location for the transmission cooler.

    You will not need a separate thermostat because the temperature of the transmission fluid does not need to be regulated. I am looking to do the same for my Nissan Pathfinder bypassing factory trans cooler and installing a seperate cooler for the trans. Would you recomend the same? The D would provide plenty of cooling ability for your Pathfinder, you should measure in front of your radiator to make sure there is enough room to fit this cooler. Again bypassing the factory cooler is not necessarily the recommended method, but it can work.

    If you install the new cooler in-line with the old, just make sure the path of fluid is transmission, factory cooler, new cooler and back to transmission. I have added links to a couple of videos you may find helpful. Thank you for this information you give to. What do you think? You can mount a transmission cooler in location C on that diagram and it will help with warming the fluid in the colder winter months. It will still help cool fluid in the warmer temperature weather or when pulling a heavy load, but it will not be as efficient at cooling the fluid as it would be if it was mounted in location.

    If you are pulling light loads or doing some mild off-road driving, it probably would not be a problem. If you are pulling loads close to the maximum ability of the vehicle or are doing aggressive off-road driving where the transmission is working hard, then it would really be best to get as much cold air flowing over the cooler as possible.

    On the inside of the radiator, closer to the engine, is a lot of heat built up in the engine compartment. Thank you asked by: Questions and Comments about this Question Aloha! Ken I comment by:
