Do the spring codes really make that big of a deal. If u find the same truck except one is a lariat and other is xlt what would be the difference in the leaf springs

 

Did anyone every figure out what the "B" code means for transmission? I have the same code and was wondering also.

 

Yeah I have a B for trans too.

 

Tranny "A" any ideas on that one yet? I didn't see it on the lists. B6 axel = "3.73 Ls" 2004 xlt screw 4.6

 

Found out what my "B" code tranny means from a spec sheet I downloaded from Ford when I bought the truck new, forgot I had it. The "B" code means: "4-Speed Automatic Overdrive (4R70W)".
Gear Ratios:
1st 2.84:1
2nd 1.55:1
3rd 1.00:1
4th 0.70:1

Now I did find this info as well, just to through some confusion in there
Transmission Code B on a 2004 F150 is a 4R75E transmission. It is a 4 speed Automatic (AODEW).
Description found on Truckworld.com a review:
"Another improvement in the drivetrain is the use of the new 4R75E 4-speed automatic. The 4R75E is an evolution of the 4R70E that is used in the current F-150. The biggest changes are a faster computer, redesigned toque converter, addition of a turbine-speed sensor, "smart" shift control unit, and a fully sealed case filled with lifetime transmission fluid."

 

Mine is an l9
Is that a 3.55 ls?

 

Revive for what is the A code transmission?
