4L60E Transmission
Just installed Andy's Procharger set up. C5 4L60E is slipping at certain power ranges. Any advice as to can I rebuild existing 4L60E or do I need a new "hardned" one built. If I need new any suggestions as to who and how much. I have 433 rwhp with 450 r torque.

I went with the FLP-level 4, works great . I would change the converter at the same time . Andy said the 2800 is just right.

does the trans shift harder to where it is uncomfortable for daily driving?

Not that I'm the dullest tool in the shed but......what is an FLP-level 4?? Is that a kit I can add to existing tranny or a whole new transmission...also where can I get it. Like the converter idea too.

Hey Blu..... Level 5 
Why a level 5? You are the first level 5 I have seen on the board.
By the way.... Your coolant over flow tank sure is full.

Rebuid it with the FLP they are a solid company, though sometimes backlogged. Raptor trannys and others are out there. The TC needs to be built for the application too, my SY3500 is slipping above 440Hp/400tq/5400rpm. So I am going to go with a different unit.
PS I think Andy has a FLP L4 sitting in his bay.

The torque estimates on my motor vary widely, and I wanted to fix things only once. Plus it was only $700 more.

Re: 4L60E Transmission (George8211)
Yeah, I can't say enough about FLP, I would of gladly paid the extra $700.00 for the level V if it was available at the time. Not that my Level IV won't easily handle what I can throw at it but I'm sure with my addiction to power I will someday need to step up again.

No you will be just fine, if you feel it is to firm you can adjust the line pressure with predator and or other programing.
