Lots of vehicles used the 4L60e. All electronic four speeds used up to the 3/4 ton truck were 4L60Es. Caprice, Impala SS, Roadmaster, Custom Cruiser, Firebird/TA, S10s, Astro vans, 1/2 ton trucks, and many others.
Even starting in 97-98 with the new LSx engines, they are similar enough you can use them with some adaptation. The bellhousings have most bolts in common so it will bolt up, but the electrical connections and torque converter bolt pattern are a bit different. I think the programming to run the computer though hasn't changed. Some of us have modified our 4L60Es with 4L65E guts since they're an upgrade.
Look on the RPO spid sticker for the codes M30, M32, or M33. Those were the codes for 4L60E, 4L60E-HD, and 4L65E respectively.
But, for the sake of your application you'll have no trouble finding one from several sources. Shoot for 93-97 to insure easier compatibility, confirm that the electrical connection is the same (they switched them a few times; probably a lower bidder could supply connectors
) and bolt it up.
If you get one from a truck, make sure its not 4wd. Different output shaft and no tailhousing; that won't do you any good.
