If you look at the 4R70W diary you will find the answer. A unitized case is more common that the A4LD 4R/5R setup. The pump serves as the front "end plug" for the cavity in the case where the guts are.

I have wondered why FORD did the separate bell on the A4/4R/5R and the conclusion I came to was that by using a seperate bellhousing they could easily adapt it to many different engines.... that tranny saw a LOT of different engines in front of it before it was through.

Does the W in the 5R55W stand for wide ratio? If so what different ratios does it use compared to the 5R55E (1st and 2nd)? Do the internals of a 5R55W fit in a 5R55E even though the case is different?

Yes, the 5R55W has a wider range than the 5R55E, according to this site:

Don't know about how interchangable the internal parts are. My guess is not.

This is a comparison from those links:

5R44E/5R55E

Used 1997-up in many Ford products with 4.0 L engines, and 2001-up with other engines.

This is a computer controlled rear wheel drive transmission.

Gear Ratios:
2.47:1 1st gear
1.86:1 2nd gear
1.47:1 3rd gear
1.00:1 4th gear
.75:1 5th gear
2.10:1 reverse

5R55W

Used in some 2002-up Ranger, and Explorer models. This transmission is similar in appearance to the 5R55N, but very few parts are interchangeable with it.

This is a computer controlled overdrive (five speed) automatic transmission.

Gear Ratios:
3.22:1 1st gear
2.41:1 2nd gear
1.55:1 3rd gear
1.00:1 4th gear
.75:1 5th gear
3.07:1 reverse

Anyone know the difference between the M5OD -R1,R2,R4. Is the R4 a stronger tranny? Any torque ratings available. Did Mazda use there own I.D. (M5D4)

That's a question for Spdrcer34. Take a look at his M5OD rebuild thread for some ideas: http://www.explorerforum.com/forums/...d.php?t=159665

Gentlemen, after reading all of the posts I am still a bit confused. I just purchased a 1995 Explorer Limited for my daughter. I am trying to figure out what transmission it has (A4LD or 4R55E).

The VIN is: 1FMDU34X3SUA02492

Door jamb sticker: Trans: "T" Axle: "D4"

I appreciate the help. Thanks, Mike

**BrooklynBay** · 02-19-2013, 09:49 PM

Welcome to this forum! You have a 4R55E transmission.

chiefmike · 02-19-2013, 09:56 PM

I am getting the Explorer for a steal....120,000 miles, no dents, no rust, no damage. Leather seats are great, carpet is perfect, no engine knock, no leaks, new tires, new windshield...all for $500. The problems are: controller for heat/cold damper, switch in the fan controller and a transmission 'problem.' They said it jerks when shifting from first to second and back down to first. Not sure of the problem yet, so I will probably be asking for more advice. Thanks again. Mike
