4x4 does not work - Ford Forums

I have a 2002 4x4 Ford Explorer. The 4x4 does not work. None of the LED's (Auto, High, or Low) on the switch light up. With a volt meter, I checked to see if voltage was coming to the switch. It does & as the dimmer for the main lights are dimmed, the voltage is reduced accordingly. I accessed the switch was bad & replaced it. This was not the problem. No fuses at all are blown. A mechanic connected it to his scanner & got a code 735. This relates to 5th grear not being correct ratio. It has no 5th gear, but has an automatic transmission. He checked the grease in the crank case but levels were fine. It has only been used once or twice but the last known time it worked, all was well. Just one day when I tried to engage it, all seems totally dead. Please advise what to look for next.

Please get the correct code for the concern. It should be a PXXXX code like P0735. I tried a few combinations of the 3 digits you posted, but no luck.

Your right, it was P735. It gave reference to incorrect 5th gear ratio. It has no 5th gear. It's automatic transmittion.

It would be a P + 4 digit code. Did you mean P7350? Not a valid code.

It was P0735. Relating to improper 5th gear ratio.
