The B&M 70273 SuperCooler is universal stacked plate transmission oil cooler that is built from the same rugged black aluminum construction as all other B&M SuperCoolers.
The SuperCooler 70273 comes with 1/2″ NPT fittings which will require you to source your own fittings, but this allows you to construct your own custom lines such as -6an or -8an braided lines for a higher quality and secure connection.
Like all B&M SuperCoolers, the stacked plate design of the 70273 gives drivers an estimated 30% more transmission fluid cooling efficiency than traditional tube and fin designs while, having 15% less transmission fluid flow restriction which allows for maximum cooling.
Based on its size and construction, the B&M 70273 would be best suited for daily driven trucks and SUVs, performance street vehicles, and light towing and hauling.
This cooler shares the same characteristics as the popular B&M 70264 with the only difference being the fittings. The 70264 utilizes basic barb fittings and includes a complete installation kit with hose and mounting hardware.

B&M 70273 Installation
The B&M 70273 SuperCooler comes as a stand alone cooler, so there is no installation kit included unlike other coolers in the B&M lineup. Because of this, installation will be dependent on each vehicle’s application. Most will mount and install transmission coolers in front of their vehicle’s air conditioning condenser and radiator, so the installation of the 70273 will require you to get your own mounting hardware and trans cooler lines.
The biggest thing to consider when installing this cooler is where to mount it. Depending on your vehicle, the 1.5″ thickness may make installation a tight fit, so be sure to find a place that receives more than adequate air flow to the cooler.
