      On my way on the information highway I stumbled across this:

      http://www.drivetrain.com/autotranscrossref.html#FORD

      Aerostar 1986-1995 A4LD
      Bronco II 1985-1991 A4LD
      Explorer 1991-1994 A4LD
      Granada 3/1985 - Up A4LD
      Mustang 1987-1993 A4LD
      Ranger 1985-1994 A4LD
      Thunderbird 1987-1988 A4LD

      What is noticable is that if the A4LD is a little bit too weak for the Explorer, how does it work on the BroncoII then..?

      The question is... can I just get a tranny from a granada and put in my explorer? Is it a perfect match or is there differences between models?

      Regards

      As far as "basic guts" goes, each model year's A4LD was the same regardless of vehicle to the best of my knowledge (possible exception might be single versus double wrap band). Running changes were made improving various aspects of the internals throughout the years, so laters ones were better than earlier ones. Valve Bodies are a different story. Pre about 91, the trannies were single solenoid. Starting in 91 (I think, not entirely sure this is the right date) they went to 2 solenoid. So you would need the right era (1 solenoid or 2) for the computer control to work. There were some valve body calibrations that differed between various applications, but I would not rank those as "mission critical" and would suggest a shift kit and VB rebuild in any event. Lastly, I am not sure that there may not have been different bellhousings depending on the application (2.8, 3.0, 4.0), but I bet someone on this board could comment on that.

      Glacier. You know it can be unhealthy, nearly on edge of sanity to actually know so much about transmissions. I am glad youre out there.

      lol. yer right. I'll soon be doing a photo thread on the Transfer case rebuild. Probably do it on the Ford ranger forum (Rangerstation)..... but anyway I'll get my mind out of the transmission gutter...

      Thanks for the kind words!

      '86-88 Aero A4LDs have a single solenoid, for OD Inhibit.
      '89-until the 4R44e/4R55e changeover, they have two solenoids, adding one for computer control of the TCC lockup.

      I've had both.
