Would a 4R44E bolt up to a 4.0 SOHC?

[scramblin]

I'm just trying to figure out if a 4R44E will bolt up to a 4.0 SOHC motor? Anyone know?

Thanks,
Kendal

Probably would, but why?

The SOHC puts out ~ 225 lb-Ft.
Torque converter multiplies that by 2, so you end up with ~ 550 lb-Ft.

The 4R44E is only designed for 440 Lh-Ft max...Sounds like a recipe for disaster.

Aren't your trannies electronically controlled too? I don't think it would even work.

Hey,

I was just asking because someone was interested in buying my tranny, but it was going to be going behind a 4.0 SOHC. I'll just refer him to this thread and let him make his own decision about it.

Thanks for the tips.

(Yes my tranny is electrnically controlled)

That's why there is an 'E' on the end of it

Breakdown of Ford's tranny codes:

First number is the number of forward speeds. In the 5R55E I am using, the 5 means 5 forward gear ratios (Even though it only has 3 actual gear settings)

Second is a letter. The R means rear-drive.

3rd and 4th (Sometimes 5th in the Lightning's case, 4R100) stand for maximum torque the tranny can take safely. Add a 0 to the end of it. So the 5R55E can take 55 + 0 = 550 lbs/ft torque.

The last symbol says if it is electronically shifted or not. In the 5R's case, it is.

Also, the SOHC puts out at maximum, 250 lbs/ft @ 3,400 RPMs and X2 = 500. If it made 225, it would put out 450

Awesome. I always wondered where ford came up with the names for their trannies.

So how much torque is a Ford A4LD rated at? Or for that matter, Ford's AOD-E? Also, what does the T (or was it S?) and W mean with regards to the newer 5-speeds in the 2002 + Explorers such as the 5R55T and 5R55W? What about the 4R70W? No "E" there, but the one in my '95 T-bird was certainly electronic controlled. I believe the "W" meant "wide ratio" but can't really think of what the "T" or "S" might have meant. On some transmission, Ford may have used this nomenclature, however they certainly didn't do it with all of them or when they revised them.

Yes, but the 5R55E and the like is their new standard. W is indeed wide ratio. The 5RR5W has a bit shorter gearing, and is used in the 3rd Gen X IIRC. The S at the end of some tranneis means Synchronous, while an N stands for Non-synchronous. I have never seen T...you must be thinking of N or S. The transaxles seem to use N or S while the rear-drives use E.

On the Taurus, the transmission that began in it was the AOD (Automatic Overdrive). This is the same one used in most all of Ford's FWD vehicles, and there was a much better (Gee what surprise) rear-drive counterpart to it. It became electronically shifted in 1991 with the new bodystle and was named the AOD-E. Somewhere along the lines, the name got changed to AX4S (Automatic Trans-axle 4-speed Synchronous).

This link shows all of Ford's trannies and gives all the ratios. A really neat website in my opinion Ford Transmission Ratios

Don't forget the ATX, the 3 speed auto transaxle in the 80's Escorts and Tempos...

Umm, whee?
