Borg Warner 1352-066 (# off tail end) T5 transmission. Had it in my v6 s10, but I don't know what it was originally in. 

Part numbers: 

13-52-066-933 off tail end

13-52-065-914 off middle

It is a GM transmission

Date stamps read 1992 and 1993.

 It shifted well when I ran it, it's been sitting for a while. I have not taken it apart to look inside. If you have any questions, please feel free to message me. Thank you.
