what transmission would be in a 1995 gmc sonoma high rider 4x4 automatic? its a tiny little truck like the s10.

 

Possible 700R4. look at the door sticker.

 

i dont have the truck or i'de just crawl under it. and the guy who's selling it knows nothing about transmissions. i also highly doubt the transmission type is listed on the door sticker. at least its not on any of my newer chevys. this is right around the time the 4l60 came out and the 700r left. anybody?
