I am wondering exactly what year 6.0L motors will work with the 4L60E. I thought someone said the crank was different in a certain year/model (HD or 2500 series) and would not work with 4L60e. Thanks.

 

Ya there is a difference in the 6.0. The 2001 and newer will work for you. The 99 and 00 are the ones that don't fit because of the crank. The 2001 and new require a spacer between the motor and trans. Other than that it bolts right up.

 

The spacer is not needed with a 4L60E or 4L65E transmission.Early 6.0s had a thicker crank flange to work with a 4L80E and later versions 01 and later were offered in Escalades and Denalis used a 4L65E didn't need the thicker flange.The spacer was made to install a 4L80E to the late model crank for use in HDs and 2500s.

 

I thought that the spacer was needed if you were to run a 4L80e with the motor. But I do recall hearing that a 2001 would just bolt up with my 4L60e.

 

Sorry about that info i was thinking it was for the 60 not the 80. Ya it will bolt right up.

 

So in other words....any of them will work???? Which years are considered the better years, and anybody got any ideas of places to find a deal on one. Ebay seems hopeless!

 

Answered the question I was getting ready to ask! 6.0 is going in today!

 

NO! Re-read above. The 99-00 6.0 will NOT work with the 4L60E. Those early ones only work with the 4L80E.

2001 and up is what you need.

Use spacer with 4L80E.
Do not use Spacer with 4L60E.

 

Thank you! My head hurts, but I think I'm straight now!

 

LOL I hear ya! Just got mine in and did not use the spacer!! Perfect fit
