BigDawg Posted May 5, 2003 Report Share Posted May 5, 2003 I was wondering if anyone on here knows how much horsepower a 4L60E transmission can take before it has to have some built internals. And also if it is better to buy a new one than a used one. Quote Link to comment Share on other sites More sharing options...
SamZman Posted May 5, 2003 Report Share Posted May 5, 2003 I know once you get in the lower 12's a stock tranny wont last long at all. I'd suggest getting it built. Depending on how fast the car is you'll just be constantly rebuilding if you put a stock one in.. Quote Link to comment Share on other sites More sharing options...

MrMeanGreen Posted May 5, 2003 Report Share Posted May 5, 2003 Lows 12s or 400rwhp (in that ballpark). Quote Link to comment Share on other sites More sharing options...
gillbot Posted May 5, 2003 Report Share Posted May 5, 2003 450TQ is what it's rated for according to GM. Quote Link to comment Share on other sites More sharing options...

God I hope that is off, I put 490+ tq to it and ran low 12's with it. It seems to be holding ok. Quote Link to comment Share on other sites More sharing options...

It seems to be holding ok. The T-56 is rated for 450 TQ as well....doesn't mean shizzle. My car has put down 588 RWTQ, and my tranny is just peachy. MANY people have put WELL more than that through the T-56 without an issue. Of course, a 4L60E != T-56 strength, by a long shot. Quote Link to comment Share on other sites More sharing options...
Clifford Automotive Posted May 6, 2003 Report Share Posted May 6, 2003 if you have no plans on turning 500+ hp then you'll be fine, the 4L60's and TH700R4's are GM's best transmissions to race with. That's coming from someone who has blown a 700R4 up... Quote Link to comment Share on other sites More sharing options...
SamZman Posted May 6, 2003 Report Share Posted May 6, 2003 A friend of mine ("STOCK 95") had an auto C5 w/ heads/cam and nitrous. He blew up the tranny atleast 3 times before he totaled the car and went back to f-bods. I think it cost like ~2,500 bucks each time. He swears against auto C5's, though I have seen a couple fast ones. Quote Link to comment Share on other sites More sharing options...
gillbot Posted May 6, 2003 Report Share Posted May 6, 2003 I've seen guys blow through 4L60E's stock let alone modded. I think the 4L60E is alot like the 10 bolt in the F-Body, kind-of a tossup. May or May not break, personally I'm not gonna risk it. I don't beat on my car alot and it doesn't see much track use, hell it doesn't see much but the inside of the garage!

ZYUL8TR Posted May 8, 2003 Report Share Posted May 8, 2003 If I hear the word 4L60E, I laugh. I hate the 4L60E/700R4 trans. Nothing but a POS (built or not). Quote Link to comment Share on other sites More sharing options...
Guest stevil Posted May 8, 2003 Report Share Posted May 8, 2003 When my 4L60E goes, and it will, I'll be replacing it with something else. Quote Link to comment Share on other sites More sharing options...
