Got a 99 RCSB with a LQ4 in it, with a 4L80e, that is now grenaded, and i picked up a new one from a buddy for a good price, BUT the 4L80 i bought came out of a 98 K3500 with a 454 in front of it. Just wanting to double check to make sure that this one will work. I believe i just use the LS converter and flex plate and im good to go, but not 100%. any input is appreciated

 

yeah it will work. you will just be missing the 12 o'clock bolt hole, what year was your previous 80e?

 

i believe it was out of an 02, but im not 100% i aquired the pickup with the 80e already in it

 

That truck has demons!
