4l60e to deadhook 450whp Gents,
I've finally got the car running well making 450+ through the 9"...but I need a trans. I want to stick with a 60e and am just wondering how far I need to take it. Basically, I'm thinking something like the rpm level 5/6 or equivalent and wondering if I need a 300m output shaft. I'm running a loose circle d 3200 stall (flashes to 4200) and just wondering if it is advisable to spend the rather exorbitant $500 extra for the hardened shaft or any other extra bits. Please don't say go 80e as I am not interested in one for this car.
Dyno thread here if anyone wants to see

It really depends on what you want to do with the car, if your going to use a transbrake and sticky tires I would be concerned on twisting the splines of the stock shafts over time.

This is a transmission I did for my girlfriends brother, he put down 470 rwhp in a ss4000 converter 4l60e heads cam LS3 swap and a stock 10 bolt with 3.23 gears....

Stay with the 60E at 500rwhp you'll be fine, I have been running mid/low 10's for the past few years without issues(well the flexplate cracked last year, get good SFI unit!)
Don't do a transbrake...if this car can cut 1.4 60' leaving from IDLE with a 3.23 gear..well nuff said
Also look like this 60E gives 6 speed cars trouble from rolls

The trap speed went up 1 mph per run...for the past year the shift points were set close to 6,600 or so..The guy I work with in STL that street tunes data logged these runs and tried 6,700 shift point, then last run I think was 6,800 or maybe even 6,900...seemed to help a bit dialing it in....

I have done a lot of builds similar to this black car, all going strong. I have the same build in my truck with the exception that I tried to "soften up" the feed holes in it, shifts like butter at part throttle, nice kick at WOT, if this 400hp+ nitrous 60e can live up in a lifted 4x4 TURD, then a lightweight 450hp camaro shouldn't be much issue, 2 years strong daily driving, daily streetracing...LOL 3600 stall FTW

Silverz good info.
I guess my question boils down to: given that I will use a 60 and plan to hit it as hard as I can on stickies is the hardened output shaft ('that appears to be the only difference for rpm level 5/6) worth the extra dosh, which is $500...or should I consider other specific upgrades?
...and yes, the 2-3 shift is very borderline as it sits today. I've flared through the shift and banged the limiter twice. I added one cup of fluid and the flare is gone-ish, but the shift is getting sketchier by the run.

If its a BILLET shaft, then yes, nice upgrade...hardened shafts are also nice just half price then the billets..the black car above has the hardened output...the output shaft usually breaks on VERY hard 1-2 shifts...I've seen a stock shaft break at 290 rwhp due to the b&M shift kit that was installed, overlooking their instructions they remove the 1-2 acc and block it off...wow big no no...on that same car I removed that shift kit, did my own tricks, did a budget build with stock output and 2 years later went 1.39 60' leaving off idle 530 rwhp ..stock output can live at 450hp if the converter is loose and the 1-2 shift pressure is perfect, but I always recommend hardened output at 400+ and billet output at 550+ just to be more on the same side

Should give years of trouble free miles, keep the trans from overheating and you'll be fine. Talk to a few of the vendors they'll let you know what you need. The 4L60E has been perfected over the years.

I have a built stage 7 FLT trans that I want to sell! It has billet input and output shafts. This thing would be great for your application! I am going powerglide for a turbo setup and this trans won't work for what i want to do.
They are guys running a 800rwhp plus through the same trans. You wouldn't have to think about the trans again. Pm if you are interested.
