Joey Mack Posted January 10 Share Posted January 10 Is the snapring in the center of the synchro installed or broken. If it is left out, it will only shift once, and then you have to go back in to the rear box.

mechohaulic Posted January 10 Share Posted January 10 a slide clutch in backwards. it's time to walk away /take a break and have cup of coffee or ==. been there dun that . the frustration of what's wrong will cause "confusion" on the thought process ; walk away and come back SOMETIMES helps . in going through the gears are we talking of top covers off and manually moving sliders or shifting with covers on? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73739-t310m-transmission-problem/#findComment-544883 Share on other sites More sharing options...
