interchanging and matching 97 & 96 tranny's - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know there is a ton of info out there on the web AND SHOPS but wherever I look, I find a different opinion that tries to sound official and it contradicts what others are saying. For example one place says a 97 4l60e 4dw tranny from a suburban is a direct swap for a 96 and vice verse. But a 97 tranny from a pickup they say will not fit in a 96 burb. I am thinking of upgrading to a 4l80e and my cousin is offering to by the 4l60e off of me but will it fit in his 97 1500 truck? Are the input shafts the same? Are the bell housings the same between the 96 & 97 years? Do the transfer cases mount the same? Are the pin connectors the same? Does the PCM need to be reprogrammed?
