Transmission spacer and flexplate
I have a 2003 GMC Yukon Denali XL with the LQ4 6.0 it had the lone crank i thought because no spacer came off with flat flexplate and it had short bolts installed that held flexplate the trans was ether a 4L60-E or 4L65-E the dealer told me it had the 4L65-E the bell housing has a bolt hole 12oclock at top of trans the trans numbers are 3KZD255B34162057 my motor blew up so I got one out of a 2002 GMC Silverado or Sierra 2500 HD with the LQ4 6.0 only thing different is that it has a short crank i would thank since it had a spacer and dished flexplate and long bolts that held flexplate. the truck had a 4L80-E trans so in order to put the 6.0 into Denali with the 4L65-E what do I need to do

I have a 2003 GMC Yukon Denali XL with the LS3 6.0 it had the lone crank with no spacer and flat flexplate with short bolts the trans was a 4L65-E the motor blew up so I got one out of a 2002 GMC Silverado or Sierra 2500 HD with the LS3 6.0 only thing different is that it has a short crank with spacer and dished flexplate and long bolts with the 4L80-E trans so in order to put the short crank 6.0 into Denali with the 4L65-E what do I need to do
I'm sure someone else can chime in but I think the long cranks are only in 99-00 lq4s. None of those you described would be an ls3 should only be lq4 or lq9. LS3 is the newer 6.2. I was also pretty sure the 4l65 couldn't fit on a long crank without a custom converter or flexplate. Are you positive what you took out was a long crank motor? And in that case a 4l65e? I had a 2002 lq4 that was on a 60e that had a dished flexplate, no spacer. The absence of a spacer doesn't mean it's a long crank. Put it back together the exact way you got it out should work just fine.
