Chances of stock 4L60E holding up with...
....6200rpm redline, 415rwhp, never using a R compound or street slick tire and I have a B&M 24,000 tranny cooler installed.
I saw in searches that the main reason the stock trannys go are when people spin them up to 6500-7000rpm. My cam would only need to go to 6200rpm anyways so who thinks it will last? I know they can go stock and some can last into the low 10's but what are my chances.
I'm debating on buying a performabuilt stage 2 or just use the stock tranny and get my Yank ss3200 installed. I really really don't want to drop $1800 on a tranny I won't need yet. Thanks.

its a crap shoot. i just put a stall on my stock tranny. had a shiftkit installed and the guy looked everything over and it was a great looking trans from what he said (nothing wrong with it yet). so im going to stick with it. no need to drop 1800 on something thats not broken yet. that and you can have a stall cleaned at most company for under 100 if you trans does go.

Keeping a 6200 redline, street tires, and a good temp and it can/will last. Dont let the naysayers fill your head with ****. There will be lemons in every group and parts will fail but I would say your odds are good. You will be doing everything in your power to preserve the trans. WHEN or IF it breaks, call up a sponser and have them hook you up. Then up your shift RPM.

All I can tell you is, "so far, so good". No idea about
actual RWHP but trapping 112MPH at pretty much
full weight.
With the SS3200 you have a sort of reasonable STR
and won't be putting near the torque or RPM of the
MegaThruster 4400/2.7 type setups, on the trans input
shaft. Not as low as my 2.0 STR but not crazy either.
I think if you get reasonable line pressure vs torque
profiles in the tune, dial back (but not delete) the
torque management and give it the biggest cooler you
can, it'll live long enough to break the rear instead.

I have about 42Kmiles on my car and it had a TCI 3000
for about 10K and the Fuddle for over 20K of them. Not
more than 20 track passes but plenty of street rompin'.
Automatics do contain "wear parts" but I have seen no
signs of degradation yet. I do believe that a low STR
keeps you further from outright breakage. But people
eating bands and clutches, is not breakage, it's more
likely glazing from inadequate apply pressure for the
torque it's up against. Bad tunes can lie about that bit
(the torque) and end up starving the trans.
I would for sure not put a stock trans with stock tune
pressure profiles and so on, up against a 50% higher
input torque and expect the same luck I have. Let
alone with stuff like ported MAFs and other airflow
(hence torque model, hence line pressure) buggery.

Hughes performance makes a kit for the 4l60e. I'm most likely going to get it and install the upgraded servos from TCI. Doing it myself so 600$ in parts plus an xtra capacity pan and big cooler should get me a decent/reliable trans. Mines at 151k so a rebuild is needed. Anybody had any experience with either?

Thanks for replies guys, staying with stocker for now but it has sometimes not been downshifting to first from 30-32mph, it does downshift more than half the time but it is still embarrising the times it doesn't. Also from 55-60mph cruising and wanting to go to 3rd or even second sems like it takes more gas than it used to. Fluid level is good.

I never have had any luck with the stock 4L60E. Always hitting the rev limiter or frying the 2nd gear. Hope you have better luck than me. I'll never regret getting the Stage 2 Performabuilt. I got tired of the tuner blaming the tranny people and vise versa. Know what? The tuner was right!

ive sprayed mine on 100 shot making 450 + rwhp for a year straight now. all i have is a billet servo and raised line pressure. i have gone through 8 trannies in the past and i learned that spinning kills them. ever since i switched to a drag radial i have had NO issues whatsoever!
