LQ4 yr? TH400 spacer needed?
Hey fellas,
I am pretty sure the LQ4 I have is a 2003, which means i should only have to use the regular LS1 flexplate to mount a TH400 to it. Or is it the later ones that need the spacer? Here are some pics of the

I have a 2003 LQ4 in my 2001 SS, use the LS1 flexplate and not the LQ4/4L80E flexplate. Only the 1999-2000 LQ4s used the longer crankshaft, the others (LQ4s) used a spacer in between the (flat) flexplate and crankshaft for the 4L80E. The LQ9 used with 4L60E used the LS1 (curved) flexplate.

That is because your 6.0L was mated to a 4L80E.

You will need the spacer and 6.0L/4L80E flexplate. The flexplate is the same one used from 1999-2007 on 6.0L with a 4L80E. The crankshaft in 1999-2000 6.0L had an extra thick flange to space the 6.0L/4L80E flexplate properly, which was different from the LSx flexplate. In 2001 GM used only one crankshaft and incorporated a spacer for engines used with the 4L80E.
Engine is from an 01 yukon denali if it makes a difference.

I just bolted mine up with all the same parts and I needed to drill new holes. I used 1 existing and had to make 2 new.
