axle and tranny door code

[qtrhors1]

My 95 F150 XLT 4x4 302 auto shows door code U for tranny and 19 for axle. The tranny is a 4R70W and gear ratio is 3.55(open). Seen some conflicting info while surfing for this info. Is this correct?

thanx Tim

19 is 3.55 rear axle. Owners manual and experience tells me so. As for U being a 4R70, I can not confirm. Sorry.
