4L60e B-85 series tramsmission

[ZeroFluxGiven]

What's up fellas... I need some knowledge in regards to my 2002 Silverado Z71  5.3

My transmission went out on me, and I got a replacement from a guy, another 4L60e, but out of an Envoy apparently. According to the codes anyway. For a 4.2 engine. V6

Now, will this be compatible with my truck since I have 5.3...also did not get torque converter with this transmission. 

Need help with this as I'm at the end of my wits with this project

It *should* work, but I'm not sure if the Envoy version uses the 300mm input shaft and TC that the Silverado does. Also, the Envoy may have one less 3/4 friction (like the V6 full sizes received) and as such, won't last as long with the additional power of the V8.

Thanks for the info.
