Blew my 4l60 the first time racing......I mean, passing an Acura. He wasn't expecting that!It will bolt up, but GM found it necessary to upgrade the standard 4L60 and call it a 4L65 which is what you find in Denali Yukons and Escalades. The 4L60 & 4L65 are built from the same transmission case. I believe it to be a 5 gear planetary gear in the 65 vs. a 4 gear planetary in the 4L60. If/when dropping a 6.0 into a vehicle it didn't come in, I would see the value in upgrading your trans to a 4L65.
