Terry Long Posted August 18, 2022 Share Posted August 18, 2022 🥲2006 Mack Pinnacle T313LR tranny the splitter for the high range gears stopped working. At times it will shift normally then will not shift into the low position it is like being in neutral. Anyone have knowledge of the splitter cylinder? A diagram or advice about cleaning and replacing O rings etc?  HELP!!

Joey Mack Posted August 19, 2022 Share Posted August 19, 2022 I just made a repair on a T-310, with the same issue.. I pulled the range fork out and found it had worn tip's,, but really not the worst iv'e seen,, i re-ringed the piston and cylinder and replaced the fork $600.00 for the fork.... (Through MACK) Why ???..... I test drove the truck, it range shifted correctly.. Look at PAI for the parts... Do you have a tranny re-builder in your area that will sell the part's? I use "Overdrive Rebuilder's" In Concord N.C. when ever I can... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70305-maxitorque-es-t313lr-splitter/#findComment-506810 Share on other sites More sharing options...
