Red Horse Posted September 6, 2022 Share Posted September 6, 2022 Any clue on weights of Duplex, Tiriplex and Quad? Big ones that would have been used with 675/6. Quote Link to comment https://www.bigmacktrucks.com/topic/70401-mack-trans-weights/ Share on other sites More sharing options...
JoeH Posted September 7, 2022 Share Posted September 7, 2022 The old 2 stick Mack transmissions are usually around 1,500 lbs I think Quote Link to comment https://www.bigmacktrucks.com/topic/70401-mack-trans-weights/#findComment-508768 Share on other sites More sharing options...

Thx- reason I'm asking not Mack related but Ford is going to start offering the 10 speed auto used in F-550-and I think F-600, in the 650/750 Power Strokes. You can get a 750 with a 37,000 GVW. In questioning the durability of the 10 speed as it doesn't weigh much more than the 6 speed currently used, I'm thinking 4 more speeds, how does it NOT weigh substantially more -as in Mack Duplex/Triplex/Quad. Answer I'm told is the Ford 10speed makes use of planetary gear sets- the Ravigneaux concept, which I never heard of. The Mack two sticks?? Just a lot more iron i'm sure.

Freightrain Posted September 7, 2022 Share Posted September 7, 2022 I always wondered if they didn't count a lock up converter as a "gear"? Or at least 1/2 gears? 1, 1 lock up, 2 , 2 lock up, etc. Quote Larry 1959 B61 Liv'n Large......................

Most of these newer automatics use combinations of clutches and brakes to get different ratios through the planetary sets. Lots of weird goings-on in there. 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Planetary sets I'm told is how Ford gets 4 more speeds out of what looks like the same case. Google "Ravigneaux" That is what concept is.
