torque converter bolts don't line up with flywheel - Pirate4x4.Com : 4x4 and Off-Road Forum

Has anyone had this problem? WTF? The motor is a 2006 6.0 from a GMC. The trans is a 2000 from an excalade. Both are LS motors. The escalade a 5.7 I believe to be LS1.
What now? new torque converter or flywheel?

What did the 6.0 have for a trans? And dont forget to try every spot. It will only bolt up one way. The Excalade I think would of had a 4l60E. You dont list what the 6.0 came from but i bet it had a 4l80E bolted to it. And there not the same flywheel. For one the 60e is 3 bolts and the 80e is 4 or 5.

It was a GMC Denali pickup. It may have had a 4L80E in it. I did try every rotating the converter 3 times. still it didn't line up.

Do some searching, this is a common issue. The LSX line has used a number of different flywheels. The bolt holes themselves could be the wrong diameter or orientation, or the dish/offset of the flywheel could be different too. Any LSX flywheel will bolt up to any other LSX. I'd say you probably have a flywheel for a 4L80 so it's different. Try and find one from a 5.3 or a 5.7 and you should be golden.

That truck has a 4L65E a heavier duty version of the 4L60E.

The 4l80e is the same bolt patern as the turbo 400 it will not line up with the 4l60e You will have to get the fly wheel for the transmission you are runing.
