Hi everybody this is an update after driving two thousand on my new/used tranny. My MIL is off, ABS is still off and works great. I haven't had time to wire the cruise control so that doesn't work right now. But I did notice a slight vibration/like a heat shield rattle around 70miles up to 80miles an hour. The first thing I tried was rotating the drive shaft since driveshaft and rear diff are from two defferent vehicles. I moved it one hole and that actually made it little worse. Now it's vibrating a around 40 and 70 MPH so tomorrow I will try to move the drive shaft to another hole. So I wonder if anyone have felt this or heard it when they did a manual swapt and how did you fixed it. I personally thing it could be driveshaft bend or out of balance.
