Why are 4L60E's so weak?!?

I love how these threads get started. Someone bitching about a 60E, then someone chimes in telling them to go 80E, then the guys with tech knowledge get in and start talking technical. Always the same trans thread. It is what it is, theres a lot of variables in a trans with all the moving parts, oil passeges, and now electronics, who knows when its gonna go. Just get in and drive.....if it breaks fix it
So I should just throw caution to the wind and just drive it? No game plan whatsoever.
In the end, I probably will swap the 80E in. I'd rather swap it in before the 60E gets ruined. I'd rather recoup the money from a good runing 60E.

The reason 700r4's seemed to last a lot longer than a 60e tranny is because the Ls motors make waaay more power stock than your sbc vortec motors and what ever. Obviously, GM did not upgrade hardparts to keep up with the added power of the LS motor. On a performance note, many people have reported better ET's when swapping to the 80e because of the more desirable gear spacing. Heavier yes but, no one has reported bad fuel mileage because of the swap either. The only down side, if you want to call it that, is the 50-60 lbs. On a 5k pound truck, it ain't gonna matter.

Thanks for the link. They say the loss isn't that bad in that thread. A 60ftlb loss is huge. I think people were focusing on the 8 hp loss instead. you would really have to see the graphs and compare where the loss was.
Either way, if that's what it takes to run the setup without failure, then so be it. I'm not that concerned with the added weight. My sub box weighs more than the difference. LOL!
