I know all too well about trans failures Superado lol... This is 4L60 #8.... Rearend #4, converter #5, and motor #1

 

im going for high 11's on motor this season in my ecsb, then plan to spray it 150-200.

 

ill get kicked off of the track this season for not having a roll cage. ill post a video for ya hahah.

 

im on motor #3, Trans#3 rearend #2. all with in a year and a half. the stock trans's that i had didnt like the spray to much. went in the high 12's wit it just on a shift kit at 5600 lbs.

 

I called it quits on 60/65's after blowing the input drum on my RPM L5 only running 6# of boost. I went thru several stock and stock w/servos & shift kits before going to a built unit. I believe if there were a stronger input drum option for the 60/65 besides a sleeved stock drum, I would have tried my RPM unit one more time. I have no regrets of swaping to an 80 though.

 

I push myn pretty hard, and it holds up. The only thing that usually breaks is the converter. But I have snapped an outputshaft too.

 

"Who has pushed the 4L60E?"...alot of guys...right after they break, they get out and "push"

 

I'm planing to put 80 in my truck. I'm pushing 7lb of boost and I'm afraid to go Wot. I'm saving it for the dyno at the end of the month.

 

I don't think I would be scared to go WOT on your setup at 7psi. I ran 11lbs on my t70 and 5.3L for four months with a ton of abuse. I had at least 50 8psi launches and over 200 pulls at 11psi and my trans didn't even flinch. The 6.0L on the other hand scares me.

 

Im still running 5psi, and ive trashed a few transmissions...
