I emailed the gm heritage center to find out empty weight of my topkick. ( didnt want to scale it)

anyway, they got into the details of the motor and trans. So they said it was equipped with a 3116 and a MMO 6 speed manual transmission, not much info online. Is it borg warner? Allison? what is MMO 6 speed?

I read other forums and they all seemed to call it a mm6? made by a company named tremec?

I thought the 6-spd manual behind the kittys in the topkicks were Eaton.
