A4LD: Is a Ford Automatic Transmission that has an Overdrive. Desigened for the V-6 engine... But, also used on the 4 Cyl. engines. In the '80s - '90s. ( Caps = Are more for my bad sight, then for others.)
I'm asking anyone that knows anything about the A4LD 2nd. to 3rd. to O.D. Shifting mecanical / electrical Workings... ( The Vacuum Modular works fine on 1st. to 2nd. shifts.)
