Description

B&M automatic transmission deep pans provide additional fluid capacity and cooling ability. No modifications to the dipstick are needed. They include a drain plug for clean and easy fluid changes, and are available in chrome or cast aluminum. Filter extensions are included for those applications that require the filter to be moved closer to the bottom of the pan.
