I am not financially able to buy a brand new transmission for my blazer but a nice gentleman offered me a 480LE out of his chevy van. Please tell me I can put this in my blazer. And if not where can I locate a good used 460LE in San Antonio?

 

The 4L80E is physically much larger and longer than the 4L60E. You could try looking through car-parts.com narrowing your search to places near you.

 

Take the 4L80E, sell it, and but yourself a nice 4L60E!
