      Well, I searched but was not able to find it on this site. So in case someone else searches for them, I thought I'd post this info here:

      Axle Codes

      L - Limited Slip Differential
      C - Conventional Differential

      Code ... Ratio
      41 ...... 3.27C
      42 ...... 4.10C
      43 ...... 3.08C
      45 ...... 3.55C
      46 ...... 3.73C
      D1 ...... 3.27L
      D2 ...... 4.10L
      D4 ...... 3.73L
      D5 ...... 3.55L

      Transmission Codes

      Code .................. Model
      D (1997-2005) ..... A5LDE / 5R44/55E
      D (1992-1996)...... M5OD-R1
      J ....................... M5OD-R1
      J (2002-2003)...... R1HD / M5OD-R4
      M (2000-2001)..... Mazda M5D4
      M (1997-1999) .... M5OD-R2
      M (1992-1996) .... M5OD-R1
      R (2002) ............. 5R55W
      T (1992-1995) ..... A4LD
      T (1996-2001) ...... 4R55E

      Yeah and I didn't think to look in the dedicated transmission forum because I didn't even realize there was one.... this site just gets better and better.

      Can somebody please explain where the transmission id code is on the
      door?
      I found the door tag and the rear axle code but I don't see the word
      "transmission".

      Here is what my tag looks like (roughly, typing this from a note made with my wife dictating over the phone). Please let me know if an actual pic is needed, and i will make one when i get home.

      -----------------------------------------
      M8102 ...... TYPE- ...... TRANS ...... AXLE
      ....................................T..............41
      ----------------------------------------


      This means 'T' - A4LD transmission

      Thanks for the help. My tranny is a 5r55s. It seems that this isn't the most
      popular series in 02.

      possible error in transmission code on door?

      I have a 1995 XLT with the transmission code 'T' on the door, however it has a 4r55e in it. I have been inside it once already and it is definitely not a a4ld as it has all 6 solenoids etc. curious if anyone else has noticed anything like this?

      thanks
      The bumper frame says max tow 3500 lbs. with 350 max Tonge W.
      The trailer I want to tow is about 3000 lbs max loaded.
      Should I just get a regular class 3 hitch to be on the high side.

      as for the 4800 lb , is that because of the tranny being a 5r55e.
      or the 3.73 rear end.?

      mine has O.D. shutoff on the columm.

      I would put a proper trailer hitch on and not tow off the bumper.

      so i have an 1995 eddie bauer limited v6. do i have the A4LD or 4R55E. the transmission was swapped from the original and i do not have park. also it appears as if it doesnt exactly line up in one spot where the casing of the transmission meets the engine.

      You have the 4r. As for the line up issue, a transmission's bellhousing's overall shape doesn't usually match that of the engine as a transmission model can fit multiple engine models and an engine model is often compatible with multiple transmissions. As long as the bellhousing is flat against the engine all the way around, then the two should be properly mated and aligned.

      Towing and the xmission ....hmmmm

      My 2005 Sport Trac has a Code of "D" on the door sticker which according to the above posts means it has a A5LDE / 5R44/ 55E xmission. Now the dumb part......what does that tell me about the transmission...especially since I'm thinking of towing.

      Front Diff Year compatibility?

      I have a 96 5.0L AWD Eddie Bauer. The front diff is starting to grumble, am I correct in thinking that given the correct ratio, they should swap from 96 to 01?

      I also have a 99 Explorer Limited with a growly front axle. The dor code says D4, which I assume means a 3.73 rear, does this mean the front must also be a 3.73? Logic would seem to dictate that, but I want to make sure before I buy a replacement.

      thanks!

      Sweet. At least now I know what I need to GET, but I should probably still confirm this by looking at the tag on the unit, correct? (it'd be my luck someone replaced the door!)Where is the tag usually located- one of the bolts you can't reach with the diff in the vehicle?

      Thanks for the extremely rapid reply, btw.
