The B&M 70274 is one of the largest transmission coolers in the B&M SuperCooler line up. With its over-sized stacked plate construction, the 70274 is one of the more heavy duty.
The B&M 70274 measures 11″ x 11″ x 1 1/2″, making it one of the biggest stacked plate transmission coolers you get buy.
Like with most large stacked plate trans coolers, drivers can expect to see a significant drop in transmission fluid temperatures. The combination of it having a highly efficient stacked plate construction and its overall size help keep transmission fluid cool in even the most extreme conditions.

B&M 70274 SuperCooler Specs
Just like all B&M SuperCoolers, the 70274 features a highly durable black aluminum construction that provides efficient fluid flow through the body for maximum cooling. It is designed with 48 cooling rows of cooling, very similar to the Tru Cool H7B.
Overall, this cooler does a phenomenal job at keeping transmission temperatures as low as possible, which is why it was featured in our towing and drag racing guides.
It uses 1/2″ NPT threads, which allows for the use of -6 or -8 an lines and fittings for a more secure fit and greater fluid capacity.

B&M 70274 Installation
If you are looking to install the B&M 70274, you need to consider placement. Due to its size, this cooler will not be able to fit on all applications.
However on most trucks and modified cars, it would be easier to install compared to a smaller commuter car.
When considering this cooler as a stand alone (bypassing the stock cooler), it is certainly large enough to handle the transmission cooling needs of most applications.
While is it typically recommended to utilize this cooler with the stock radiator cooler, it can certainly be used by itself as a stand alone cooler that bypasses the radiator.
