Any year 4l80e will work. The only noticeable outside difference is the cooler lines. Pre 97 has the cooler lines in the front by the bellhousing. 97 and newer has one line by the bellhousing and one right in the center of the trans.

94 or 95 was the earliest that will work, as long as it has the p/n switch on the side, it will work.
Had a stock 95 in mine, sprayed a 350 shot on it for years.
