What is MMO 6 speed trans?
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?
