4l60e To 4l80?

[zittman]

I have a 2000 Chevy 1/2 ton with a 5.3 in it now. I've been reading up on to change over the 5.3 to a 6.0 that I have. I was wondering about how difficult it is to change over to the 4L80 transmission and making things work? Or would it be easier to use a built 4L60E or a 4L65 better? I'm in the process of building up the 6.0 with better camshaft, throttle body, cold air, headers and exhaust. Thanks

In a lighter truck you'd appreciate a beefed up 4l60e over a 4l80e. The 4l80e is geared different so you'll loose a little on the acceleration and the 4l80e is a monster as far as weight goes compared to a 4l60e (4l60e=164lbs - 4l80e=255lbs). The rotating mass will hurt the HP reaching the ground too. Unless you towing heavy or going for 1,000hp a 4l80e will be more work than its worth.

Here a link to some pictures to see the size different between the two.

everybody has their own opinion on this issue if you blow up the 4L60E you might want to go with a 4L85E.
