Is there a good way to make the 4L60E hold up to a constant 425 and every once in awhile hit the juice? I would go with a turbo 400 (or something in that range) but id love to keep my OD for those shot trips. thanks guys

 

Don't know much about the new 4l60e but yeah... the TH350 or 400 is more than up to the task. There are also quite a number of beefed up 2004R and 700R4 trannies out there hanging in at the proposed power level.
Then again... we talking RWHP or flywheel... big difference.

-Mindgame

 

mine doesn't have a problem thus far- only 5000 miles though.
i'm guessing i'm at 400hp. When i add heads i should be around 500

this is all flywheel of coarse.

built 4L60E-

its very important to cool it! i am going to upgrade to a remote tranny cooler somewhere. i am going to get creative
A deeper pan as well

 

Just so you know im talking about RWHP. A 396 with a few goodies anyways, would i be better off trying to build a 700r4 over the 4L60E? i acyually thought the 4l60e was a better built transmission. oh well anyways, thanks for the replys

Assuming you have a good rearend go to this web site.

Very interesting.

Don't forget to dump the 7.5inch rear if you have one.

8.5 it boy.

 

Im building a 9" right now so i dont think that will be a problem. Would i just be better off going with a 400 3 spd instead of spending 3000 to 4000 bucks? I dont know if i can put that much into a tranny. I looked at lt1dave.com and he had a pretty good build up of my stock trans for a grand but im hearing it wont last very long.even with only 500 horse? thaks again for the replys

FLP Level 4 Trans set up for a bit of N2O. www.flp2win.com

I will have mine in next week.

 

Smokn '94 Z-- do you have a broke down parts list of what that transmission build up consist of? like i said before lt1daves.com has a build up for about 900 with core. thats a grand cheaper than flp's but i dont know what all flp kit consist of. anyways thanks for the reply

 

Try www.ls1speed.com they have 3 levels of trannies. You get a new Tranny plus $600 for your old one.

 

see the link in the sig

 

Check the tranny in the sig...

 

I have a 700R4 with a vig. 4000 T/Q built by Dave that I will sell for 1,600.00. I will even pay to have it freshened up before any one takes delivery.

 

Jeff-
What are you going to be running with the new engine?

 

I'll get all that info Friday when I drop my car off at FLP. If you can wait that long. I do know they do something a bit different if you tell them your running N2O. I'll let you know.

 

i dont have that much power but my a4 WILL hold it
4l60 with hardend steel pump and vains ect. and vacum operated pressure regulator 230lbs line pressur at idle over 300 at WOT kevlar cluth kit bla bla bla if interested i can get you in touch with the man who built it about $1500 is what mine was but it will last mine has about 15k miles on it
