  • Trans Retarder air pressure

    Posted by Art on December 31, 2018 at 10:08 am

    Why is there a air valve or regulator used on a Allison Trans retarder, what could make it use a lot of air pressure ?

    Air moves the fluid from the accumulator to the transmission vanes to make the retarder work.
