My 80-E has a slight whine to it in first gear. I have heard this is normal on the 80-E's. I dont have the flywheel dust cover on the it and im sure that is also why i can hear it. Hopefully everything will work out. I have had my trans in/out of my truck 6 times. It is well worth it. Like everyone else said, worth it in the end. Smoooooth sailing after.
