4L80E swap in depth w/ pics
Have you stopped to realize something. The originater of this post (Orionslp), doesn't even own this car anymore. Why? Simple, because the 4L80e slowed in down too much. It's just an absurd swap.
He sold his car because of the transmission? That's like selling the car if you have a slipping trans. Sad story there, eh, I guess I have more determination than some. A TH400 with overdrive isnt as horrible as you try to make it. Tons of LS1 guys cant get 60E's to hold, they go to a T56 or TH400 and then realize they can have the power holding of a TH400 with overdrive and many eventually switch to 4L80E's. When it becomes more popular and/or you start building them, I'm sure you'll sing a different tune.
If they still had a '60E in them, they'd be running even quicker and would rebuild 4L60E's on weekdays.

With all do respect Frank you need to relax your attitude about some things. The 4L80E isnt the big bad monster you make it out to be. You're going to see more and more LTX/LSX cars running these trans. If you have a better idea on how to harness 800-1100hp with a 4 speed auto, let me know.

I've been building 4L80E's since 1991, when they came out. They have their place...In the TRUCK that pulls the car trailer that the race car is on/in. The 4L80E has had a terrible problem with line pressure instability, and hard parts breakage, whick became more of a problem in the later units, when they went to "central lube". Do whatever you want to, but just remember, you were warned. I was trying to do you a favor. If you've got yourself set on a boat anchor, by all means, don't let reason and common sense stand in your way.
