My transmission is leaking and a friend has a good transmission out of a 99 Montainneer that had a 5.0 in it. My truck is a 1996 5.0 with 4r70w. Will this work.

 

Don't you think you should try to fix the leak instead? And everybody says the 4R70W didn't come in our trucks.

 

The 1995-96 I'm think came with 4r70w. I hope its just front seal. But just in case I was looking at the transmission.

 

There is information that says our trucks came with the 4R70W, but everyone says they did not. The 4R70W doesn't bolt to our old bellhousing style. It should be the E4OD.

 

4R70W
A revised version of the AODE was released in 1993 with the Lincoln Mark VIII. 4R70W stands for 4 gears, Rearwheeldrive, 70 arbitrary number assigned by Ford and Wide gear ratio. It has lower 1st and 2nd gear ratios for better take-off acceleration and improved gearset strength. On vehicles powered by a 5.4 L V8, a stronger gearset is used than in normal duty 4R70Ws. In 1998, due to durability concerns, the intermediate one-way roller clutch was replaced with a mechanical diode providing extra holding capacity and longer service.
While there is speculation that the 70 can be multiplied by 10 to indicate the ft-lbs of torque this transmission is capable of handling including torque converter multiplication, (i.e. 700 ft-lbs of torque), there is no reliable source indicating this. In fact a Ford document stated that the 2003 "Expedition's 4R70W transmission is rated to handle up to 506 foot-pounds of torque, which provides a large performance cushion beyond the peak torque rating of Expedition's largest available engine." http://media.ford.com/products/press...423&make_id=92 . It is more plausible that the number indicates the torque handling capability in N-m, as 506 ft-lbs converts to 686 N-m which could be rounded to 700 N-m. The "70" may also refer to the transmission's torque capacity after torque converter multiplication which occurs at low rpm's when the torque converter is more "elastic".
The gear ratios are: 1st: 2.84 :1 2nd: 1.55 :1 3rd: 1.00 :1 4th: 0.70 :1 Rev: 2.23 :1

My truck has a U code for the transmission on the door tag. Witch according to this site is a 4r70w.

My 94' also has a "U" code on the door jamb but, my Ford Dealer and TCI transmissions says it's an AODE.

From TCI Transmissions:

We have a rebuild kit, but I do not think you have the 4R70W. I believe
that you actually have a AODE. The Ford trucks up to '96 still had the old
school push rod engines. The 4R70W was never used behind the 5.0 or 5.8 in trucks. I need you to dig deeper into the VIN code with a dealer, and get
back with us.

Thanks,

As it turns out, he was right and the "WEB" was wrong.... do what you like... I'd still just replace the seal....


IMHO, I think the "WEB" get's the AODE-W and 4R70W confused, they are not the same, similar but, not the same.

4R70W = Modular engines
AODE-W = Pushrod engines

 

Thank you. Now I remember who told me.

 

 

So does anybody know if transmission will work or not? Thanks.
