Does anybody here remember the torque numbers and ratings on transmissions on trucks.

Now I know 9513 cause my Kenworth had one, but my Mack which I still have, I know it has a 13, but I can't remember the torque rating on it, which I believe they are a little different from all the rest, I know at the time I bought it, it was higher then any other. Another thing, when it comes time to change oil in it, the thing takes a whole 30 gallons just for the transmission and rears, with maybe 1 pint left over.

When my Kenworth had almost a half barrel left over.
There is a 12515 the last 2 numbers tell how many gears it has, and the front numbers are the torque ratings.

so I know 9,5 and 12,5 does anybody know any others? Thank you a head of time.
