my 5.3 is out of a 2006
the 4l80 is out of a 2003

right now it has an aftermarket converter in it to use with the stock 5.3 flywheel and 3 bolts
the replacement i got is for the 6 bolt flywheel

what stock flywheel do i need to use to make the 4l80 bolt up to the 5.3 not using spacers, adapters, drilling or washers to make it work correctly?

12563532 SPACER

19257940 BOLTS 6

19260102 FLYWHEEL

These are the OE GM parts you need for the 4L80 on an LS block.

You could also get a TCI 4L80 SFI plate - 399754

thx for the extra info

i was just under the impression there was a factory optioned 5.3 to 4l80e that used the 6 points , id been told they were in express vans but i had 0 luck finding any or even a part number.

mercuno

So to clarify,,, I need nothing else but the tci plate?? No spacers or anything,?
And then I can use either my 60e converter or get an 80 e converter? Or does it only take 6 hole pattern

READ
THE
STICKIES

Jesus, bumping a 6 year old thread becuase you're too incompetent to read?
This info is all spoon fed in the sticky.

Also...If you could just google...this is included right in the Summit Racing listing for the part number in the post you quoted
"Notes:Flexplate to crank bolts and pilot hub adapter included. This flexplate is designed for use when bolting a GM LS-based motor to a 4L80E and utilizes the 6-bolt mounting pattern. This flexplate is dual drilled with the 11.50 in. and the 11.063 in. bolt pattern. This will not fit 1999-2000 6.0L applications with 0.400 in. extended crank flange and came with flat flexplate. This will not fit 1999-2000 4.8L applications that originally came with a manual transmission."

And for christ sake NO you can't use your 60e converter...the pump drive is totally different.

Wow I used to get all kinds of **** for talking to someone like that. Even got banned a few times and switched user names.

Guess it's cool now........or the moderators turned into pussies. It's a load of **** either way.

Worst thing I said was "christ" or "incompetent"
Didn't know that was so bad??

"Incompetent" is not a word worth being banned...

Without incompetence in the world to varying degrees; there would be no service industries!

And I would be a broke ****...
