I havent looked at the differences much, but it looks like the yoke is different so far
But my question is if anybody knows what would be needed to swap a 4l80e in place of a 4l60e?

 

what are you doin the swap in your blazer cause i have been curious about this myself

 

Yes, i was thinkin about replaicn my 4l60e with the 4l80e because its obviously stronger, and my trans is on its way out. Im too afraid to change the burnt fluid because of what i found out about it
