It has an Aisin At45 transmission I believe. Just be sure to follow the installation instructions for whatever pto you install. Muncie or Chelsea. Installation instructions are available online. Had a customer put the return line in the incorrect port in the transmission and it burned the clutches. I ended up swapping out the transmission. Aisin transmissions are used in Hino’s and Dodge trucks with the ISB Cummins as well so there is plenty of information out there.
