I’m not sure sure in your record tho. I built a trans (4l60e) for a guy quite a few years ago who supposedly held the stock botttom end gto record and it was a 5.7. It ran either 10.60 or 10.80 at 130ish. I can find out more details on it, and that was over 10 years ago and the trans is still working.

 

Does every KFX thread end like this?

 

like what.

 

Trying to convert people to not hating 4l60s.

 

Its just fun messing with people who hate on it or the 6 speed in a boosted car and immediately swap to something else

 

exactly. And it also agitates me that people have formed a hate for it because they had a incompetent builder and tuner.

 

​its strange that most all transmission builders suddenly become incompetent when a 60e lands on their bench, but bang out 80E's and 400s all day....competently.

 

This is gonna get good

 

Hey now I don't just hate the 4L60, I hate all autos equally! Really has nothing to do with building and tuning though...

I know the reply to this already but because how I am, I gotta say it anyways. I can give you the phone number to two friends of mine that would 100% disagree with you from experience. Both of them have had multiple issues out of th400’s. Hell, one of them text me the other night because he was thinking about getting rid of the car because in about 6 months time, the 400 has been out the car going on the 4th time now. It’s a 10.50 car, no reason for it to keep failing. Is it the transmissions fault? No. But let’s just say a th400 is much less complicated than a 4l60 so room for error on a 4l60 is much smaller. I know you are a pretty intelligent fellow and can understand where the real problem lies, if you would stop being so stubborn. I see a lot of people bag on the 4l60. But the issue is mistakes made when building it. There’s stuff you can get away with in a 400 that won’t fly with the ‘60. When I first got into trying to go fast, I was having this shop build my 700r4 for me. I was told it was beefed up. Whatever that meant. Well the thing only lasting 6 months at a time, I decided to try and build it myself. When I took it apart, it was NOT beefed up. It was all stock. With crap clutch fibers. Wonder how many shops do **** like this because they know the customer isn’t going to take it apart and check. Let me give you a hint. A lot. I’ve worked at two transmissions shops. One of them was aamco. Number one important thing is profit. You think you gonna get a warranty on a transmission that’s in a sports car, especially one that has stuff done to it? Yea right. They don’t care. They will say it’s abuse. Not to mention most of the time when you get a rebuild, they will reuse clutches if they still “look” good and then cookie wheel the steels instead of replacing them. I see this ALL THE TIME. I also see these dip ***** remove the 3-4 release springs thinking that will allow a harder clutch apply. But what they don’t realize is 1) it releases the 3-4 clutches so they don’t drag 2) do you really think if they weren’t needed that gm would put them in millions of units? That’s a time of money saved right there If it’s not needed.

im not gonna lie. I could go on and on about this ****. But I’ll just keep it to myself. Basically there’s gonna be two people arguing this. One person is the one who simply says they are **** but yet doesn’t know how to build one and has had multiple failures in the past because of incompetent builder telling him the trans is a pos when simply he doesn’t address the real problem and pay attention to details. The ln the other person is like me. Knows how to build them and knows the limitations of it. Would I advise someone with 1000hp to use one? No. But 600-700hp is doable. Anything above that and you are gonna beat on it, make plans for something else. It has its place.

I see people with mild builds or even stock stuff having issues all the time. Builder error. There’s this guy my son is friends with. He had gone through 8-10 repairs/rebuilds whatever. It’s like an 02 5.3 with a small cam, stall and gears. There’s no reason for having all those issues except builder error. He had to pay every time it failed. Of course he was just fed the same excuse every builder throws out when they can’t make it live, it’s just a pos. That’s the easy way out. But it’s cool.

 

are you serious? I hope you are being sarcastic and I’m not picking up on it, because if you are being serious, I can never trust anything you say. It has 110% everything to do with build and tuning. No question about that. I could make one error in the time and smoke that bitch in short order. I could also make a mistake building it and smoke it. So I’m not sure how your statement could be remotely accurate.

 

I aim to not disappoint lol.

 

For one I would never, ever, EVER go to AAMCO lol

Out of curiousity what's the 4L60 record? 400 and glides have been faster then pretty much everything but how fast has a 4L60 been of any build level? I've seen some quicker 4L65's but nothing terribly mind blowing. You can throw those in too if you want.

I've had about zero issues with autos from a mechanical standpoint. Stock 6L80 lasted way too long. Had TH400's from FTI, CK Performance, etc... had an ATI ProGlide worked perfect. The only thing lacking in those setups was the cars soul, must have dissipated out the trans cooler. Manual trans cars just seem to have more character to me, driver being more in tune with the car if you will.

 

You missed what I said... my hatred of autos has nothing to do with building and tuning, it has to do with sucking the soul out of a vehicle. I've tuned tons of autos, trust me I get it.

 

You did that long ago building an engine for 135MPH

 

Dude!!....I wanna say this was a low blow, but I'm laughing hysterically .

 

ok. I didn’t read it correctly I guess. Because honestly I think you know that tuning and building has everything to do with it. When I read that (wrong?) I was like this isn’t something this guy would say.

 

everyone fails at some point in their life. Just ask your mom. Oops. I had to. Lol





Disclaimer. my mom passed away several years ago, but I don’t get offended at the mom jokes. So hopefully you don’t either if your mom isn’t around. So I guess this is like a pre-apology if that’s the case.

 

hey he got me. But everyone doesn’t always succeed on their first outing.

 

Aww man, c'mon. Let's keep it to cars, dog on his car or something, let's keep family out of it. I know I'm out of my lane for commenting on this, as it wasn't directed at me, but still.
