Replace a 97 4L60e with 2003 4L60e question

[TempestT-37]

I have a 97 4x4 Tahoe with a 4L60E. I have bought a 4L60e out of a 2003 4x4 Trailblazer. What are the differences between these two transmissions? What will I need to swap from my 97 to make the 2003 work? Thanks

Mainly converter size and flexplate mounting. The 2003 unit will have improvements that may not have been done to your existing unit yet. The bell housing will be different but should not effect mounting at all.
