vibration problem
To the OP , If the vibration only happens in acceleration and deceleration it is usually the pinion angle not being correct...... Also, I see a lot of guys are having vibration trouble and there is a lot of good info in here to check but I want to throw something else out there that no one has mentioned yet.... My transmission guy who has been rebuilding transmissions his entire life and has done 1000's of mopar 727's mentioned to me when I was putting mine back together after he rebuilt it for me.....He said if you have a EXTERNALLY balanced motor and are using the stock flex plate as I pictured below , which would then require the weighted torque converter...When you put the 4 bolts into the lugs on the converter make sure the small hole that I circled in red is across (opposite) the weights on the torque converter.....He said if not you will get a vibration for sure.... Just throwing it out there....may help somebody out
