How can i tell if this has the Allison tranny?
I'm looking at an 02 avalanche with the 8.1L. I saw the the RPO code is supposed to be M74 for the allison transmission, but the guy who's selling it cant find that code anywhere in the glove compartment. He also couldnt find the code MT1 for the 4l80e. Are we looking in the right place? Whats the easiest way to tell what tranny the avalnche has? which is the better tranny? thanks

Whats a 4l85e??
