Will a 1991 or a 2002 transmission fit in a 1995 Blazer?

Ask a wrecking yard, they have the Hollander interchange book that tells them.

1991=no Its not electronic.
2002=maybe, if the 1995 is PWM (Pulse width modulated) and it does not have the removable bell housing.

Need to know more about the trans coming out of the 1995.
