A gear ratio change without updating the computer to recognize the change can make the trans go crazy.Robby thanks for the reply. My Commander is a 4x2. The differential didn't completely fail. I began to hear a grinding sound that would increase under acceleration and decrease under deceleration. Initially it was mis-diagnosed as seized rear callipers, hub bearings and something else I can't recall at this time. I finally found a mechanic (I'm in Honolulu) who thoroughly diagnosed it and ruled out the afformentioned issues...metal filings were found in the interior axle shafts...I then took it to 4WheelParts and they diagnosed the gear and pinion.
Once the work was completed That problem disappeared, but now I have a larger, more expensive one. We'll drop it off @ a local dealer Monday and pray it doesn't cost an arm and a leg.
So if the gear and pinion is not the same ratio as OE-spec, you're saying that will cause this issue and not low fluid? Thanks again.
Yes if that's the case it's possible the dealer can simply reprogram the computer to accept the new ring and pinion and you will be fixed up.So if the gear and pinion is not the same ratio as OE-spec, you're saying that will cause this issue and not low fluid? Thanks again.
Term: Sir........really not necessary.Robby I was not testing you Sir...I'm not nearly smart enough to test anyone on the topic I just spoke with the service advisor...apparently the culprit is the new 3:21 gear and pinion set. Now I get to fight with 4WheelParts to rectify this problem. The mechanic cleared the code, road tested the Jeep again and the same code returned...more to follow. Thanks...
