I just purchased a used 2004 E350 Econoline 15-passenger van with 6.8L V10. The door code for Transmission is "E", which I believe is for 4R100 4-speed automatic overdrive.

The Axle code is "34". I believe this is a 3.73 ratio, but cannot find any reference to AXLE 34 on this site. I'd like to know what this rear axle ratio is, and whether it's LS or not. Thanks!

Hi Ed,
It looks like axle code 34 is a 3.73 dana style non limited slip axle and trasmission code E is a E4OD/4R100 transmission, hope this helps.

Thanks, Lewie. I really appreciate the response. May I ask you how or where you found this information? I've been hunting everywhere without results!

Ed, I work at a dealership and there is a chart in the parts catalog of what the codes
mean. Lewie
