Re: 4L80E Questions by Bubba The Bus Tech

This sounds like it might be the very deceptive lock up shudder, does the shudde buck stay continuous or just momintaarily? continuous could be an engine miss from coil failure, wire break down, 50 mph is the right speed for this to appear for some reason. The trany shop ran into this a lot, the engine makes good power and fuel economy but drops a cylinder when locked in over drive at about that speed. otherwise you have trany trouble, expensive trany trouble.
Good Luck
