need help decoding trans

pp = new process
833 is model 4-speed
3356 - date assembly code = Monday, October 5, 1970 (71 model year)
0038 = 38th trans build that day.

seems to match up with the tail shaft... No I would not say junk that's for sure. recount the splines again as it looks like may have been converted to the "HEMI" guts 18 spline? which would make it pretty desirable to some...
