Re: 4L60 swap not 4L65E.
I would think the lockup would be the same on a 700r4 and 4L60 - I thought they were the same transmission but just renamed at some point?
Just to be clear - you keep mentioning the 4L65E as the next trans and it being a 1/2 step away....are you talking about a 4L60 or 4L60E as your current trans?
pretty sure its like this:
-700r4 (aka 4L60)
-4L60E
-4L65E
