1981 Mustang Door Tag, Tranny Info?

5.0ForLife · 04-26-2007

Can someone please help me with the Door Tag Info? In the bottom
right corner where it says "TR" my code is W. I need to know if this
makes the tranny a C3,4 or 5. I read a thread a while ago that had a link for a decoder for the whole door tag. that would be great. Also my
code for axle ratio is 8. Is that 2:73 gears? any help here would rock.

AX 8 = 2.73:1 non-locking (w/o Traction-Lok differential)
TR W = C4 auto
