yes the transmissions are the same. both use the 4L60E, you may have to change the tail shaft housing.

SOURCE: I have a 99 K1500 Suburban with a weak 4l60e

yes. 96-99 are the same. 95 are different. 94-88 are the same. thats the most i can tell you off the top of my head. As long as the trannis are the same type they'll fit. For example a 700r4 from an 86 will fit into a 88 with a minor adjustment. But an 86 700r4 will not fit into a 86 that had a TH-400 without major changes. So as long as they're both 4L60E within the years mentioned above they'll interchange just fine.

Is the van rear wheel drive?
Same transmission, same configuration? If they are, call your local salvage/junk yard. Some friendly guy there can check the Hollander Interchange Manual to see if it's a direct swap (that's about all the manual tells-yes or no, on a direct swap). If it's yes, clear sailin' for YOU! But if it's a no, you will have to find the differences to see if it's still a feasable venture. (I wanna know, too.) Several things come to mind: is gearing the same for same final drive ratio? Electronic shift points the same, same computer hookups, (the '97 would be OBD II) Can you incorporate the controls into your suburb? I hope you find an answer.
