MightyFruit Trucking Posted March 4, 2014 Share Posted March 4, 2014 Ordered a New Granite with an Allison in it and noticed an up charge to change PTO from air shift for manual transmission to hot shift for automatic. Trying understand the difference? Quote Link to comment Share on other sites More sharing options...
Kansas farmer Posted March 5, 2014 Share Posted March 5, 2014 A hot shift has clutches in it so you can shift it in gear fluid engages it. An air shift means you need to stop the truck clutch it and the shift the pto in gear. The hot shift can be shifted with the truck in gear and moving althought I would not recommend doing it at high speeds. Quote Link to comment Share on other sites More sharing options...
MightyFruit Trucking Posted March 6, 2014 Author Share Posted March 6, 2014 Ok! Thanks that make sense being that the truck has no clutch. I'll tell you with this allison I'm starting to see the benefits before I even bring this pup home. It seem that it will be a lot easier on the Operator! No worn out leg, both hands can stay on the wheel, black topping, milling will be much easier! 1 Quote Link to comment Share on other sites More sharing options...
Mackdaddy2030 Posted April 13, 2014 Share Posted April 13, 2014 So does that mean it can accidentally go up while driving? Quote Link to comment Share on other sites More sharing options...
