It's hard to set up a 4L60E to hold up with the power levels we are at.

I have an FLP level IV, and 6 lug Yank 4400 stall.

Chuck @ FLP and I will be doing some testing with my car (418ci stroker and 4.10's) and push it hard. Might result in screwing up the tranny but we can always redo it.

Good news, and good news!
Yesterday, Ellis pulled apart my 4L60E for freashning and some upgraded parts. After a full racing season and lots of 1st to 3rd's (OBDI problem). The tranny's 3/4 clutch pack only had 1/3, of one side burnt off <img src="images/icons/smile.gif" border="0"> This is with a 400rwhp and 3800lbs car (some N2O runs mixed in).....Needless to say, I was very happy with the results. I also use only Kevlar, and not the "Alto Reds" so, I'm sure it helps with heat, but not holding power. I believe "Colonel," your right, on the mark about racing a full season with 500rwhp! A little juice is fine on my car (125 shot) for mine, once in a while. I am supprised though that the Kevlars take the punisment (lots of tuning in the pressure tables for the tranny). Thanks Ellis <img src="images/icons/smile.gif" border="0">

No amount of fluid changing will make a 4L6O-E stand up to 500 RWHP weekend after weekend. This I've proven. You got big power? Better get rid of the 4L60-E unless you like rebuilds every 50-75 passes.

Go with the Yank 4L70!!
Works GREAT in my car with the TP4400 converter.
Mike @ Yank can point you in the right direction, but this tranny kicks *** IMO <img src="images/icons/grin.gif" border="0">

if you want to keep overdrive go with a 200-4r.if done right they can hold alot of power, there are 8 to 9 second cars out there(none f-bods most gn's)but they work.i don't know about the yank 4L70 i know it's 200-4r but the one i saw was just a stock 200 4r with a shift kit and none of the billet stuff.now thats stronger than a 4L60E but it still could be made better.as far as price goes it might be cheaper to go with a turbo 350- 400.

You guys get me on the floor rolling every time you bring up the GREAT 2004R!

Glad you like that trans I did for you Jimbob! Not that I really know what I am doing <img src="images/icons/wink.gif" border="0"> <img src="graemlins/burnout.gif" border="0" alt="[Burnout]" />

I'd recommend giving Chuck @ FLP a call. You can get info on his level IV 4L60E, and you can also get some info about his LOCKUP TH400. He's been working on this for a while, and it will be a GREAT thing to have for those guys with FAT converters. I had a TH350 w/ a Yank TP4600 in my T/A for a little while, and it was MISERABLE. The converter was way too loose on the highway to be able to enjoy the car. It would've been a different story if I still had lockup capabilities! Just imagine if you paired this trans up with a Gear Vendors unit. <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" /> You can get a hold of Chuck at (630)820-9294.

Yanks 4L70 (200r)comes with Billet internals.
The tranny I have now stood up to mid 10's at 127mph no problem.

JimmyKash, there are plently of high 8-low 9sec. grand nationals out there.and they use the 200-4r.
Chris ARE 360, maybe yours is but the ones i've come across have been stock 200 4r's with shift kits.someone here in houston had one that burned up first pass.and i was there when it was took apart, and it was a stock 200 4r with shift kit.and the person who took it apart(at mike from yanks request)asked mike if he wanted to put it back together with all the billet stuff, he said no put it back the way it was.just what i saw.

BTW the lock-up Th400 is built using the same technoligy that brought us the Variable pitch th400.....Which is the same technoligy that brought us lock-up <img src="images/icons/wink.gif" border="0">

A lock-up TH400 is good. But if you like TH350's why not just a a Lock-up(from factory) Th350?

Just food for thought

Here is the 2004r guru if you need a custom billeted one. If I broke a 2004R, I would have him rebuild it with all his custom parts.

i know of a lot of mid 9 second GN's and a few low 9 second GN's but haven't heard of anyone that runs consistent 8.80s-8.90s with a 200-4R

how many passes to they last?

MARO-KEEN

iTrader: (10)

JimmyKash, they only run them for 8-10 passes then tear it down to refresh it.i think there is 7 cars in a class up north that do this.i've seen more 9.20's to 9.50's than anything else.but it's not unheard of for those times to be on a 200 4r, it's not what i would choose for race car i'd go turbo 400/powerglide w/brake.

CHRISPY

If you can run low nines with the torque a Turbo GN puts out then it will be cake in a 422 F-body even with a lot of NO2.
