Have a lq4 from a Yukon Denali 2005. Was originally mated to 4l65e and I would like to mate it to a 2001 4l80e. What will need to be done to accomplish this

 

The dished flex plate, spacer and bolts. I have a set left I think if your interested.

 

 

please look at the stickies in this section. They are literally at the top of the page. I see you're a new member with this thread being your only posts.
Read the sticky. It has the correct info. Literally in the 1st post

The only response you have right now from rpturbo is incorrect. You don't want to use the dished flexplate with a spacer. This will give the incorrect spacing. Also, the dished flexplate will have the incorrect converter bolt diameter. The 4l60e torque converter and 4l80e torque converter do not share the same bolt diameter

Use the spacer with a flat flexplate for an 80e. Something from a 2500 truck with 6.0 and 4l80e is a good place to look if you want to find part numbers...but again...check the sticky and you will have all your questions spoon fed to you.
