I HAVE A 4L80E AND I HAVE A NEW STALL. THE BOLT PATTERN IS FOR AN LS1, BUT THE STALL FITS THE 4L80E. HOW DO I ALLIGN AND DRILL THE FLEX PLATE FOR THE SMALLER PATTERN? IS IT WORTH IT TO BUY A NEW FLEX PLATE?

Odd, does it have six bolt holes like the stock 4L80e does?

IT HAS SIX BOLTS, BUT IT LOOKS LIKE IT FITS AN NEWER LT1 AND AN LS1, SO 3 BOLTS ONE WAY AND 3 BOLTS THE OTHER WAY? I MEASURED THE BOLTS ON THE STOCK CONVERTER AND BY SKIPPING ONE IT CAME TO 10 1/4" ON CENTER AND THE NEW CONVERTER LOOKS LIKE 10" ON CENTER? I AM CONFUSED? HELP!

You could take your flywheel off and drill it if it will mount to a flat part of the flywheel. If three holes line up with the existing holes you can put some kind of paint or transfer material on the new locations and then bolt the convertor to the flywheel to transfer the hole locations. I would first contact the manufacturer of the convertor to find out what they were thinking. Maybe they expect you to use the three that line up and call it good? GM had six bolts for some reason.

Your first converter had 6 bolts and everything went in fine, there is no reason this one should be different?
Same manufacturer right?
see ya,
allen
YEA SAME MANUFACTURER, BUT HE SAID IT IS THE BOLT PATTERN OF THE NEWER LS1/ls2 with the 6 .0L. IT LOOKS LIKE THE CONVERTER FITS 2 DIFFERENT MOTORS THE LT1 WITH A 4L80E AND AN LS1 WITH A 4L80E. YANK SAID THE FLEXPLATE I HAVE IS THE OLD KIND, AFTER THAT YEAR THEY MADE THEM LIKE THE CONVERTER THAT I HAVE IN THE BOX? I DO NOT KNOW? I MAY BUY A FLEXPLATE AND HAVE IT MACHINED ON THE BOLT PATTERN SO I KNOW IT WILL WORK.

:lol: I told you it was for something different than your intending!!! :thumb:
Why not just get the new flex plate from a junk yard instead of morfing one?
<div class='quotetop'>QUOTE(jethro_3 @ Nov 21 2006, 05:58 PM) [snapback]74159[/snapback]</div>THE NEW FLEX PLATE WILL NOT FIT MY CRANK BECAUSE I HAVE A THICK JOURNAL CRANK AND THE NEWER 6.OLS CRANKS HAVE THE SMALLER JOURNALS SO THE AREA IT BOLTS TO ON THE CRANK IS A LITTLE DIFFERENT. I KNEW I SHOULD'VE LEFT THE SPEED BUG ALONE. I ORDERED A FLEXPLATE FROM O'REILLYS TO SEE HOW MUCH IT IS OFF. I MAY TAKE IT TO A MACINE SHOP HERE AND LET THEM DRILL AWAY, OR I MAY DO IT MYSELF I JUST DON'T KNOW ?Quote:

YOU MAY BE RIGHT I NEED THE TRUCK FOR TOWING, YEA I KEEP TELLING MYSELF THAT.

I TALKED TO YANK AND THEY SAID SEND IT BACK AND THEY WILL REMAKE ANOTHER ONE. SO I WILL HAVE TO WAIT A LITTLE WHILE LONGER. DARN, I WAS READY FOR LOW 13'S.

Just make them do it correctly. You should not have to work around their engineering if it doesn't make sense. For what they charge for TCs they should bolt right in without any issues.

THATS BASICALLY WHAT I TOLD THEM. I DIDN'T WANT STRESS FRACTURES FROM THE DRILL HOLES LATER DOWN THE ROAD. THEY SAID THEY WOULD MAKE IT RIGHT. ALSO, I HAVE ONE OF THEIR STALLS IN MY TRUCK NOW AND IT WORKS IMPROPERLY. WHEN I GET THE NEW ONE IN THEY ARE GOING TO TAKE THE OLD ONE BACK AND CREDIT MY ACCOUNT. WHAT A DEAL DOUBLE THE LABOR FOR ONE STALL CONVERTER.
JAMEST
That bites, bro. They should do right by you. Who's stall did you buy, another Yank?
In the past all gm cars had 3 bolt holes in the TC. The only ones that had 6 were diesels and 3/4 ton and above trucks. My SS (with 4L65e) only has 3 bolt holes and has been fine. I guess it's too late now but I would say if 3 hole lines up you are good. I have ran 3 bolt TC's behind the big block in my chevelle. Sorry I caught this late.
Dave
He's using the 4L80E in one bad ass high horsepower/torque engine. Three bolts may be okay but I sure wouldn't trust holding onto 500+ hp with three little 10mm bolts. :twocents:
I'm not trying to beat a dead horse but the TC's for THM 350/400's were pretty much all 3 bolt ones. The old Chevelle is no slouch, prob around 4-425 rwhp and I never had any problems. It would take a hell of a lot to shear them. What I just considered though is the rotating mass of the 4L80 and it prob takes a lot more to turn the pump on that. My SS only has 3 bolts and I'm prob in the neighborhood of 475-500 flywheel horsepower but I have a puny 4L65...guess I'll step up one day and do the 80 conversion though.
Dave
For the money he paid they messed the first one up, now they send him a second fu^k up.... That truck hauls A$$ and he probably won't stop there.... Something about an addiction :drool:
