My 65e was doing just fine behind 7lbs of boost on my LQ9, but I was still using some TM for safety. I swapped it before it gave me any problems so I could get premium money for it. We'll see how I do with the HD2'd 80e with zero TM a lil more boost.

 

my stocker handled 451 for 2 weeks untill it let go

 

My shift kit, vet servo only 60e was in the truck for 40k+ boosted miles (30k before the turbo), 500rwhp and 12 second 1/4's (with the 4.8L), and NEVER broke. Put a $2500 fully "built" 65e in it at the same times as the 5.7L and broke the output shaft off twice, before I swapped to the 80e, . Still have the perfectly good stock 60e sitting in the corner,

 

full bolt ons/4:10's here. still rockin a BONE stock 60e with 135k on the clock. about 40k with bolt ons and "spirited" driving. lol.

 

So will servos and a shift kit help the tranny handle more power?

 

stock 4l60 will lasttill about 350-380rwhp in trucks and 400~ in cars

 

60E lasted 20k... broke output shaft's, burn clutches, and all good metal stuft in it.. my g80 still holding on..

 

How muh power are you making?

 

Yeah, the vette servos cost less than $20 and will firm up your shifts and reduce slippage, but a big trans cooler is your best investment for increasing trans life. Go with a Tru Cool 40k, it's a huge trans cooler.

 

word

i installed that same cooler at the beginning of the month went in with a breeze. also the servos can be had for like $14 on ebay.

just look for oregon performance transmissions
