I dont wanna get involved...all Im asking is can we keep it to a debate over the specific topic (the transmissions) and not attack anyone specifically. Either side. Please.

Neil, you have a valid point that I agree with completely. If something is going to eclipse 1000 HP then a 4L80E may be a better choice. Putting one in a street driven 10 second car is overkill and will have adverse effects.

Yup, cause it made my car so much slower. Also, if I decide to do a power adder, I'm covered. Don't have to "freshen up" a 60 every two years.
Only one person is getting personal, I am just looking for some science, explanations, or facts to back up claims and all I am getting is jabs at myself or long winded ramblings of how long certain people have been building transmissions.Quote:

Im not pointin an fingers...just askin it of everyone from that point on.
Its my KUM BAY YAH request. Lol
I was told by a local guy that builds high end race car transmissions and converters that a 60 is not reliable over 500 rwhp
It will hold for awhile but they wear out fast and when the band starts to slip there going to need to be rebuilt
My 4L60E has lasted 2.5 spring/summer/fall seasons now (hoping for 3 total *knock on wood*). It has not received much track time but I easily do 1-3 WOT pulls from 1 to 3rd gear everyday. I'm thinking about pulling it this winter and taking it apart to see how much wear it's actually received this time around. It was not an easy task to get it to last this long. It took 5 builds and tuning hours to nail it down to where it's at now. I sure wish I had 25 years experience at that point but I also enjoy working on the vehicle myself, I'm a hobbyist among many of us here so forking over money to someone else to do it sometimes isn't an option I like to swallow. That being said, I really wish I just did the 4L80E swap, a bunch of people told me to do it but I was hard headed. I don't care if it's heavier and I lose some power of parasitic loss... I feel I would have had far less trouble if I would have built one from the start... Even though I'm just an inexperienced asshole compared to other people who build transmissions for a day job.
A 80E is a good choice for a 1K car but if someone with 5-800hp ride they are junk and don't hold up as well as a 60E?Quote:
