I have the letter U as the transmission code on the door jam sticker what kind of tranny do I have? Its a 96 F150 5.0 automatic.

 

E40d

 

Thanks for the reply, the B&M Transmission people told me it meant I had a 4R70W.

Could this be the same as the E40D?

What are the differences between a E40D, AODE and 4R70W?

These are the 3 tranny's people have told me I have. I got a overdrive button on the end of the shifter arm if that says anything.

 

I'm not a slush box kind of guy but I'll give ya what I know...the aod4 is the early version of the e4od, the aod4 uses throttel position to determin shift paterns, as where the e4od is completly integrated with the EEC, I also believe that the clutch packs in the e4od have been upgraded. ford has a shift pack for your box it's pn#M-7101-h: this will allow you to "dial in" your shift. I would also recomend a cooler.

 

U code is the AOD-E/4R70W tranny, more or less a descendant of the old FMX. It is in no way related to the E40D (code E) or 4R100 as it is now designated. The E40D is actually a delevopment of sorts from the C-6. If you want a lot more info go to http://www.baumannengineering.com/ and rumage around their site

The answer is up above in this thread, E4OD. Also, its from 15 years ago. And in the wrong section of these forums.

 

Wrong. U is AOD-E or 4R70W, depending on the year. E4OD was always code E.

 

Anyone know where the trans code chart is located here?

I am looking at a 1989 F250 manual trans with trans code W on the door sticker. It does not look like a ZF....doesn't have the crosshatch pattern in the body casting. Trying to figure out what W trans is. I think there was trans code chart here that I've referenced in the past. Thanks.

 

I stand corrected, thanks Mark.
