Hi All, Newbie question. I am a little confused with my V8 top loader trans. A little background. Building AV8 using a 1942 Flathead/39 trans with Model A rear end. I had the the drivetrain all together and then noticed i needed to switch out the throwout bearing shaft as I will be using the Model A pedals. So I pulled the trans out switched the shaft and put together the drivetrain. Now here is my problem/confusion. I put the trans in neutral(i think) and I rolled the car forward and the transmission shook side to side. Almost like something was bent. I did not have this problem before. Below is what i have done to test. 1. Rear end jacked up, car in neutral(i think), the tires spin opposite direction and I get a clunk type movement at the u-joint. 2. Car in gear(tried all gears), tires spin opposite direction and the u-joint does not spin. Is that normal? I do not have my trans supports in place yet but it was not doing this before i changed out the throwout bearing shaft. Below is a picture of my gears. Is this the neutral position? Also is a link to a video showing the clunk at the u-joint. Link to video Thanks, Denny Sent from my iPhone using H.A.M.B.
