i used this for a few hundred miles and had a tune issue that caused the lock up to fail. It went back to yank and had all parts replaced and is as good as it was the day it came in from yank . should also have a warranty if you have any problems. I paid 1k for this not too long ago and im wanting 700 shipped to your door .

its the baddest 4l80e converter yank makes , the SC with a 3000 stall for a 4l80e transmission , it uses the bolt pattern of a 4l60e flexplate but with 6 bolts like a standard 4l80. if you use the tci flexplate the part number 399753

 

Damn, I want this.

 

offers and pm's replied too , stil for sale until i receive payment.

 

Wish I had the extra funds for this and a 4L80e right now.....

 

(sold to me) ! payment sent!
thanks, chase!
