Picked up a 200 4r trans at the local Pick N Pull . I checked the Vin before going and it show up as a 1987 Monte Carlo SS, however when I got there the tag on the transmission shows 160-871HTF.355 (HTF unknow). I expected it to have a CZF on the tag. I pulled the transmission anyhow because they are hard to find. When I got home I pulled the pan and it has a pink valve body as shown in the picture. My question: is this a real SS transmission or not?
