I've got a little bit of a problem. I have a 2006 Dodge Ram 3500 4 by 4 with the G56 6-speed manual transmission. I just got a new slash remanufactured transmission put in the truck. I'm having issues shifting up from 2nd to 3rd gear and shifting down from 4th to 3rd gear got more than 20 miles per hour. I'm not sure if it's the synchros or not, any help would be appreciated on this subject. Side note, I just got a brand new Southbend dual-disc clutch and new clutch master cylinder installed with the new transmission. I don't think this is a break-in. Issue, it could be something rather more serious like a Synchro or Master gear. Thanks!
