Purchased a '92 F-600 LoPro 6.6L diesel. Has an axle code of "T3" and a transmission code of "AE." Can any of you fine folks decode these for me please, and thank you.

 

This might not be 100% right as I looked it up in a Ford 1994 service book
number dummy say Ford switches up axle codes quite often.

AE= Allison AT-542 4 speed Auto
T3= ?? are you sure about the 3
A TE= (Rockwell) RS-15-120 W/5.13 Gear Ratio That sounds to me like what Ford would put under a LoPro with its shorter tires.

 

Thanks for the info, Bronco. I'm not exactly sure about the "3", as this information was being read to me over the phone. However, what you've proposed sounds correct. Any idea if those axles having locking diffs?

 

This book doesn't show anything as a locking diff.

Just to clarify there was NO axle code "TE" in my 94 service book.

 

T3 = 1990 F600/800 ~ Rockwell model RS-15-120 Single Speed Rear Axle / 3.73-1 / 15,000 lbs. Rear Axle Capacity.

TE = 1990 F600/800 ~ Rockwell model RS-15-120 Single Speed Rear Axle / 5.13-1 / 15,000 lbs. Rear Axle Capacity.

 

Thanks Bill! (aka NumberDummy)
