I was trying to pin down which tranny I have.

I have the following cast into the side:

RFF81P 7006 AA


My truck is a 1999 F250SD 4X4. My confusion is one website I visited showed a pic of my year being equipped with the 4R100 and that it should have side PTO port if its a 4X4. My truck has a conventional transfer case mounted on the tail of the tranny.

Okay it looks like the side PTO port is an accessory port of some kind unrelated to the 4x4. Still not sure what model tranny I have tho.

pretty sure that pto's are only on manuals. if you have an automatic you have the 4r100

 

PTOs were available on the autos, but they were an option. Most autos do not have them. I believe all of the transfer cases have a PTO port.

 

Yea Mark thats what I found too.

So it is a 4R100 then?

my 99 sd has an e4od trans with the 5.4.
brothers 99 v-10 has the 4r100e
i think the oil burners all have the 4r100 in 1999.

 

If it's the stock tranny, the F250 LD's had the 4R100 on all 5.4L trucks. The F150's 4.2L and 4.6L had a 4R70W or a M5OD. The 5.4L F150's with the California emissions had the 4R100 (replacing the E4OD), as well.

Might want to double-check with the dealer?

Mine has the V-10, just updated my sig.

I'm 99.9% sure it's the 4R100.

...I hate percentages.

 

i agree, if you have a v-10, you will have the 4r100 trans.

 

99.9% is good enuf for me, thanks bro.

good luck.

 

No '99 or newer Superduty ever left Ford's factory with an E4OD. The 4R100 replaced the E4OD when the Superduty went into production.

There is no such thing as a 4R100e.

 

With ^^ said, I'd like to up my percentage to 100.

 

would you like to look at my e4od trans in my 99 ? produced in march of 1998?
cant tell me it doesnt exist, i own one !
as far as 4r100e. google it!
