I recently changed the flywheel and am putting in a reman 4l60e. The torque converter bolts do not line up.
Parts supplier gave me pioneer FRA452 as the correct flywheel for 2003 Denali 6.0 awd
Used spacer and longer bolts as well because it hit the oil pan without it.

I installed the 4l60E and torque converter holes are almost 1/4'" in from holes on flexplate.
from what I am researching is to elongate the holes, Is the flexplate wrong or the converter?
Does anyone have the part number to a flexplate that will bolt to this converter?

truck had a 60 in it and not an 80 which would cause this problem from what I read,
Thank you for any help.

Yeah that flexplate FRA452 is for the 4L80 you need the FRA471 for the 4L60/65/70

Thank you. That still requires the spacer correct?

I don't think so the spacer is for the long crank 1999-2000 LQ4/LQ9 engines only.

Depends on dished flexplate or flat. Go to Rock Auto and find the correct plate part number. I didn't need a spacer with my 2005 6.0 & 4L60

and hopefully your trans was built to beefier specs.
the escalades/denalis had 4L65s to better-handle the 6.0 without going full 4L80. there wasn't a lot of difference from the 4L60, but it was rated for higher input torque.
