Searching the archives and other sites it is very hard to figure out what years will work in my vehicle:

1994 Suburban 2500 6.5 4x4 4L80

Any ideas?

Thanks

I make no claims about the accuracy but I'm trying to find out if I can stick a '95 4l80E in my '93 and I found this
There are 3 interchange rules for the 4L80E. First year of production, 1991, is by itself. 1992-1996 interchange, and 1997-Present interchange.

That's according to: http://www.transmissionplanet.com/techinfo/gm_4l80e_tech.asp

If anyone can confirm or dispute that, or even just tell me if the 95 will go in my 93 it'd be appreciated.
