Upgrade the 4L60E or replace?

[CoryM]

Hey guys,
I don't play with autos but a friend has a 00 camaro with a 4L60E.
Getting the normal 1870 code (TCC slipping) now that we have added heads and cam. 411rwhp and 410ft/lbs. Only mods are a 3500rpm TC and a cooler. He keeps talking about a blower and the 650bhp range, which is viable so we need an OD tranny to handle that. Anyone run a Raptor 4l60e?
I know some dragracers who run kits from http://www.ckperformance.com/ with some success.
Anyhow, when trying to build a weak tranny sometimes its better to just upgrade to a stronger design. What are the other options?
Thanks guys.

trans go makes a junior shift kit for @ $60 that has a replacementtcc valve with great install instructions. i would recomend the trans-go full kit for @ $120 from summitt (it also has this valve) shortly before i left the dealer we were starting to install these on every car with that trans/code combo. if he is honestly planning 650 rwhp it can be upgraded to handlle it. just remember you gotta pay to play, and hp ain't cheap.
i ran the transgo kit in my sbc s-10 for a 100,000 before it started slipping again. i used the tci kit for the rebuild.

650 rear wheel? I say it makes more sense to start with a 4L80E.

Thats what I was saying. But after looking around there are a couple kits that claim to handle 650+hp so I think thats what he is going for.

The 4L60E is a very tough tranny. With a few mods it can devinately withstand 650 horses. I am currently putting one together for my 68 Camaro with a 476 big block. I have seen some of the local guys run them and use the lockup in 2 and 3rd gear under acceleration. I have seen the transgo shift kit in e-bay for the 4L60 for around $80.00.

My TCI 4L60E is lasting just fine. But then again, I only have 500HP and very short sidewall 285/35 Nitto NT555's. So it's not like they hook up very well--which limits shock to the drivetrain. So the intended usage should be factored in. I wonder how an upgraded 80 compares to a built '60-price wise.
