Thats good to know..... so i take it you are going to use the TCI Flexplate and ARP Bolts for the 4l60E??

thats the plan.. for the 80e that is.
i will be keeping an eye out for the shoulder of the arp bolt to bottom out before the head is tight to the surface and add a washer if needed
my complete automatic combo is
4l80e from transformance
rossler t brake
yank sc3000 stall
tci flexplate
arp flexplate and converter bolts
denny's 3.5" aluminum shaft
hughes dipstick
b&m quicksilver shifter
BMR 4l80e crossmember
energy trans mount
actually i havent picked a trans cooler type or location yet

And BS3 controlling the shifts..............
Don't mean to hijack (even though same topic).. I have an early 4L80E I am trying to mate to a LS1. I have the spacer but it looks like the bolt patern on the flex plate is 3 holes at 9 5/8" in a triangle and the verter has 6 holes at 10" in triangle.
Do the early / later 80E's have different bolt patern?
Or does it sound like I have the wrong flex plate?
TIA
Shaun

Verdad Gallardo FYI.. Pace advised 12602448 is the replacement for PN 12580709.. However, there seems to have been a MFG'ing issue on the 12602448. All the ones Pace had in stock were not drilled with the correct number of holes and spacing from what Chuck has told me. He is getting a few new ones from GM hoping they are right.

my last update to this post.
tci ls1 flexplate, yank 4l80 converter
the 3 bolts yank supplies are too short for the tci flexplate
you need 20mm long. get grade 8 equivalent or better
the tci flexplate has 3 hole positions for ls1 and 3 for standard small block
the yank converter has 3 hole positions for ls1 and 3 for standard small block
i bought 6 bolts, and lined it up and just like JMBLOWNWS6 said, all 6 just go right in.
for 50 cents a bolt it is silly not to go ahead and put all 6 in.
i also ground the paint off of all the surfaces, inside and outside of the flexplate, and mounting surface of the converter.
yank masks over the converter holes but the entire foot needs to be paint free, as that is the mating surface.
tci may claim that they no longer paint their flywheels and use a grey coating etc... but there are plenty of new black flexplates in circulation as i just got one.
that is all

Im glad you got it all worked out bro! I am mad busy with a 402 T88 project and doing a 4l80 also in it. I will post the pics I took a long time ago so everyone can see it with six bolts. The pics suck but you can see it at least.
