This fluid is trapped.

00:00 what we’ve got here is the LBZ as this is  typical of the earlier Duramaxes with lower power outputs then we move into the 17 to 19 L5P  and then we move to the 2020 and the 2020 they did a lot of other things they put a far more  powerful cooling fan for the radiator a hell of

00:27 a lot more engine coolant radiator they upped  the towing capacity so lots of other stuff in the truck having to do with suspension etc Ram  Ford and GM I understand they’re getting near 40,000 pounds towing capacity now which to me is  obscene absolutely obscene whatever weighs 40,000

00:50 pounds it’s going to dwarf the truck unless it’s  just a big meteorite on a trailer or something so when we saw this 2020 cooler we realized  everybody with 19 all the way back to ’01 needs this thing if you do anything with your truck  that’s aggressive including tuning so we put a

01:12 kit together that allows you to do this all the  parts all the hard to find items are in the Box you can heavy duty oil cool all the way back  to ’01 you can find that kit on bankspower.com

The stock Allison 1000 5 and 6 speed transmission pans have drain plugs yet it don’t permit a full drain. Unlike other transmissions, the Allison 1000 has two filters, one external and one internal. Allison recommends changing the external spin-on filter fairly frequently under heavy duty, or “severe” use, which is how we use our trucks. Their instructions recommend replacing the external filter at 50, 100 and 150,000 miles. They want fluid changes at 75 and 150,000. So, at 150,000 you’re replacing both the filter and the fluid. Then, you start the interval cycle again. They only call for the internal filter to be changed when the transmission is overhauled. In other words, you’re not dropping the pan unless you’re taking the trans down to the bare case. 

A truck with the Banks Ram-Air Transmission Pan installed.

The new Banks Ram-Air trans pan has a magnetic drain plug at the lowest point, so the pan drains completely without removing it from the transmission. Not only is it convenient, it dramatically lowers fluid temps thanks to its patent-pending Ram-Air Scoop design. It’s now available for 2001-2019 Duramax and coming soon for 2020-2025 Duramax 10/1000, 2007-2018 RAM 6.7L with 68RFE, and Ford 6.7L with 6R140 and 10R180.
