I just bought a 2004 Blazer runs great knew the tranny was shot when I bought it. The simple question that no one seams to know is can I swap in a tranny from a 2000 Blazer? they look identacle to me right down to the electrical plugs

 

Yes, all the 1994-2005 S10 Blazers used the 4L60E.

 

Thank you, I was just worried about wiring, half of people say yes other half no.

 

Someone else here with way more knowledge about transmissions will probably be along to give a way more in depth answer. It probably depends on if its 2WD or 4WD as well.
