I have a stock 2005 5.3 silverado w/stock flexplate. I'm looking to hook up a 2000 4L80E from what I read a need a spacer on my flex plate.

Does anyone have any experience with this swap? What flex plate did you use or can I use the stock one? Which Torque converter too, looking for a Heavy duty replacement?

 

i got my spacer from gmperformance cheap.. or you could buy a ls1 to older th400 flexplate,that should work.. u need the 4l80e flex plate then buy the adapter easier and cheaper that way.. i rigged one up with nuts before redneck engineering,, it worked,, but i later changed it out,i;ll bee making more power..t70 5.3

 

u will need the oem 6.0 flexplate, spacer and for ease of use the stock tq converter. this will be the easiest way and correct.

 

You will have to re-wire some things for that Transmission aswell..
