GM rebuild identifier?
I'm looking at a replacement 440-T4 trans in the local junkyard, it has a GM reman sticker on the side cover but I can't see the fine print (dirty and out of reach). The fluid in it is it marischino red, like it just came out of the bottle. There is a bit of a stain on the edge near the block, but that could be a valve cover leak or something.
I'm wondering, did GM mark the rebuild date on these? Or if it was GM would a dealership be able to tell date and/or mileage when it was replaced?
I looked around the car, but couldn't find any paperwork.
