Are all year 4L60E compatible?

[Beaver's Chevy]

Hello all,
I have a '94 two wheel drive with a 4L60E that needs to be rebuilt. Are they all the same? I found one on Craigslist, but it notes to be for a '96 and later model...???
Any input would be greatly appreciated.
Thanks, Erin

No, you have to get one from a 1993-1994 vehicle. 1995 had a unique wiring setup for it, an 1996+ was OBD-II, and will not work with an OBD-I vehicle.

Make sure the one you are looking at does not have the letters "PWM" cast into the front pump.

actually 95 and 96+ will work, from what i understand just need to swap the harness and 2 solenoids

^^That. Make sure the one you are getting is from a truck as well, not a car.
