What are the differences between 4l60e's? I know certain years they changed the way the TCC lock up was modulated. What's the difference between a V8, V6, and 4 banger transmission? Are the bellhousings different between the 8,6, and 4? Which years or applications had the bolt on bell housing and not the one piece?
What about the valve bodies? are they different between a 8,6 and 4 for a similar year of transmission? Are there certain years that were better than other do to upgrades? Any web sites on this?
