Will not shift

bronco · 06-05-2008, 03:59 PM

Have an 04, put 4:56 gears in today and it will not shift gears with the traction control on.
I bought a Programer and changed nothing but Rear End Ratio. Any help on this.

Well I know Greg will chime in on this one but from my vantage point. PUSH clutch in.

Must be an issue with the speed sensor communication with the computer. If the computer does not see a speed signal, or one that is too slow, it will not command an upshift.

How do I get to the speed control? Via the programer? I can't go to the dealer still in extended warrenty. Would someone with a bid Diagnostic maching help me?

Disarm the T.C.

Used Hypertech programer. Don't know what what you mean by disarm TC.

Bronco: When he says "disarm TC", he means turn the traction control off manually, so you can drive in the meantime while you get the problem resolved.

As for the problem, if you used a microtuner to make the change, I am having trouble seeing what could go wrong. Usually, on microtuners, the chocies are very specific and clear - you simply pik the correct ratio that matches what was physically installed, and the microtuner makes the necessary changes in the ECM coding.

IF you had actually used tuning software instead, making the change is MUCH more error prone. On the EFILive software for example, it is compeltely non-intuitive. If you chnage the field that LOOKS like the one to change, it screws up, ebcause that is actually a CALULATED field. The correct field is elsewhere on the screen. (Hard to descirbe this is a thread posting, but trust me, it is very confusing even to professionals).

IF you used a microtuner as you state you did, assume that the chnage you made did not take hold due to some interference (cell phone for example, or Sat Nav or any number of other devices on the vicinity). Do it again, observing ALL the cautions that the mocrtuner instructions list (ALL of them!!!).
