Hello all, this is my first time posting to the forum but I thought I would give it a try. We have a 1985 Syncro with about 165k on it. We love the Rig and have taken on many adventures. Just recently when driving the past few times I have been noticing that it seems to vibrate at the lower end of each gear until I accelerate to higher speeds. At higher speeds or to the top end of each gear it seems to drive fine. The vibrating only occurs when slowing down at lower speeds in the gear or taking off from a dead stop. Any ideas on what might be causing this? I am hoping it is not a problem with the transmission and don't want to make the problem worse. Any advice is greatly appreciated!
