Its actually a torqueflight 999 iv heard they are quite sought after tbh I had never heard of one I always assumed it was a 904. I put a shift kit in the valve body like 15 years ago when I was gonna use it for the dart back then and never ran it. It has been in storage ever since I hope I did it right lol. I bought a gasket kit and a new filter for it. Transmissions is something I know nothing about I can adjust a band but that's about it lol.
