Default How much hp for how long?

Well i fryed my tranny saterday night, I want to know if you guys think a 60e will take the power im gunna throw at it or if i should look into an 80e swap. Now i have seen many 11 and even a few 10 sec trucks running on 60es so i know they can take it but how long do they take it?? Iv pulled and worked on this one 5 times already and im getting a little tired of having to worrie about it, i want it to be reliable for a lomg time. My engine makes maybe 500hp and i plan on running a 150 shot on it yet. what do you think?

Do the 80 and pretty much stop worrying about it.

After the 2nd time you should have swapped it for the 80e...if for some unknown reason you do not opt for the 80e go FLT lvl7 minimum.

Yeah the budget is tight, i havent really had problems with them burning out its always other little crap. I figered maybe if i had i completely redone it might hold up better?? I was hoping to get a little input from guys that have got a full build to see how many mile they get out of them and how hard they run them..

lol, yeah thats what i ment.. 500 crank hp in the winter time with good weather. so lets say 650 crank hp on the bottle, is that to much for a 60e to see maybe every other weekend on the street??

I had a 2000, rcsb 4x4 with a 6.0, cam, and 3200 stall I beat the **** out of a FLT level 5 for a good while, until I developed a fluid leak and smoked the 3-4 clutch pack. Replaced the clutches and it held strong till the truck caught on fire

Its the truck in my sig that went 12.8 But was about 500lb heavier than a 2wd

As many times as i pulled a 4L60E out i just got tired of them.. Put in a Stock 4L80E and never had a hickup since.
If it were me, i would have put a 80E in it after the first time you pulled the 60E out

Its an easy swap also.

I’m always afraid any day may be the last day and one shouldn’t have to live with that fear, but the same could be said with any other component when pushing things. However my FLT Level V has held up to some pretty decent abuse since it was installed in ’06 and has operated flawlessly ever since. If you have the coin and it will put your mind to rest, it may be better to do an 80E, but if your on a budget as you suggested, it may be better just to have your 60E built.
