vibration......

Well I think I have found my problem. I had replaced the sm318 trans a while back and the trans I got had a problem with the tailshaft bushing. Someone apparently ran the trans without the bushing and the tail shaft was opened up from running it without the bushing. I tried to install a new bushing but it would just push in with my fingers. Ran it for about 500 miles and have removed the trans and am rebuilding it. Found the bushing had pushed in and was not even close to being on the driveshaft input shaft. I am going to use the old tail shaft on this transmission which the bushing has to be pressed in to this tail shaft. I believe this is what was giving me a problem. New bearings and will be putting it back in today. Everything seems nice and tight now. Wish me luck!!
