bulletproof?

(3.06-1)x.30=.62+1 or the second gear ratio. if your motor makes 300lbs. of torque the overdrive in your trans will see 900+ lbs. of torque in second. with this imfo you should see that no one can change how it works which means you are stuck with the best trans amco ever had. l do not have an answer to the problem just an understanding how it works. l have nothing to sell or a fix, just an explaination of the problem. no hard feelings just good luck

john kilgore,
Are you saying 2nd gear is the weak link in these transmissions?
The majority of troubles don't seem to be 2nd gear related though.
The only real problem I have had with my 4l60 was late shifting on the 2-3 which I figured out eventually.

What the hell is it because I'm having the same problem? I've changed my shift times to make it shift quicker, it helps greatly but it still shifts a little slow.
I think my tranny is starting to slip too, but i'm hoping it completely go out for a while. Has anyone used the Maximum Evil 4L60E from ls1speed? They advertise that it will hold 850rwhp 800rwtq, does anybody know if this is true? I'm gonna be running around 450-475rwhp and plan on spraying an occasional 250shot. Would the Maximum Evil work or should i look into something different? A TH400 is not an option, OD is a must.

Art Carr once made these claims (BS), and as far as I know, there is really nothing out there that can go for 200/300+ quarter mile runs at the claimed HP (750 - 800 HP) & at least 3,200 pounds total weight & last. The real story, is that with what is available at this point in time, 650 HP is the "realistic" max. & have some sort of transmission life at a somewhat reasonable cost. I'm sure that "someone" has made SHD parts for these units, but at a astronomical cost, and not made available to everyone. Believe me, if I could improve on what is out there now, over what I am doing presently (at a reasonable cost), I would do it, and pass it on like I have always done. I have never believed hype from Art Carr, or anybody else for that matter, just what works. Do you want to know a "secret"? there are no secrets, a lot of common sense, & a lot of hard work.......

I don't street drive anymore but my FLP manual Valve Body 4L60E lasted a whole season full of 10.7-10.9 passes at 3350 lbs. I brought it to Chuck at FLP for a fresh up and it was still good.
My experience has shown that if you don't down shift these tranmissions while street driving (or any full throttle down shift) they will last a lot longer.
I'll be giving it a try in the Super Stock Class this year. Hopefully it will hold up to some low 10 to high 9 sec passes.

This just made no sense. It was NOT slipping on the 2-3. It simply would not shift or it was way way late from what I was commanding. The 1-2 would shift a bit late but was no where the problem my 2-3 was.
I then put the shift times back to stock(.500) on the 1-2 and 2-3.
Raised the mph and set rpm to 5800.
Guess what, it now shifts perfectly and hard right at 5800rpm on the 2-3 with 11psi boost. I was quite amazed at how my "performace" tuning of the shift times at been the entire problem.
I use a max shift retard of 10' advance. This kills some power during the shift but does not shut down the motor either.
I also overfilled the stock pan by about 1 qt which seems to help under heavy accleration.
My trans is a stock 98 4l60e with 15K miles and a transgo kit that's been in it for the last 10K.
I have also run this transmission with full manual solenoid activation for about 50 175 shot n20 runs before I went to the blower.
But I don't have a ton of slick runs with this car. Most all have been on dragradials with best 60fts of 1.62. So tire spin has probably helped this sucker live.

But put the belt back on and double the power and no more 2-3 shift no matter what rpm or mph I set the 2-3 at. I programmed in a 5000rpm shift with mph extremely low just to get it to shift at 6400rpm. It seemed the more power I made the worse it got.
