That part number belongs to one of several trannies used by Ford between 1986 and 1989. E6ZR-7003-FA was used behind a V-8 in 1986 stangs. The E6ZR-7003-FB was also used in 1986 with the difference being that the FA tranny had a neutral position sensor's wiring harness and connector added to the top cover's left side.
Further, between 1987 and 1989, the previously mentioned FB tranny was used behind the 302 with a 7 tooth speedometer drive gear.
Reguardless of which year it was used, the ratios are broken down as follows:
1st=3.35
2nd=1.93
3rd=1.29
4th=1.00
5th=.675
R=3.15
In late 1989 and 1990 trannies, the gear ratios of second and third were revised to 1.99 and 1.33 respectively, and the tranny used an 8 tooth speedometer drive gear. This tranny has the part number E9ZR-7003-AA.
Hope this helps.
