Newbie tranny question

Hey folks...Im a Ford guy & know nothing about Chevys...
 
I need to know what tranny is in my brothers Blazer...Its a 96 with an auto ,4x4
 
Thanks alot & if this is in the wrong section Im sorry...

It''ll be the 4L60E with the one piece main transmission case (i.e. does not have the removable bell-housing).

So no chance it would be a 700R4??
 
If not could a 700R4 replace the 4L60E ??

Nope.  And no, a 700R4 cannot replace a 4L60E without quite a bit of hassle and programming changes.

Dang,, thanks for the help....
