I have a 2000 chevy blazer zr2 2 door. I cant seem to find what tranny is in it. Iv been told 4l60e and 4l80e

 

Yeah, that's pretty top secret information. 4l60e. Of course, now that I have told you - I kinda have to kill you...

 

Lol thanks man. Whats the diff between the 60 and 80?

 

The 80 has a higher torque rating than the 60

 

 

4l60e is basically an electronic 700r4 if you remember those an the 4l80e is basically a electronic turbo 400 with a few changes of course but yes the 4l80e can handle a little more in stock form but both can be built.
