2003 Silverado 4WD. Service 4WD dash light comes on after engaging 4WD and acts up by engaging itself randomly for several days, then goes back to normal.

Check connection at the 4X4 control module , check power and grounds . Do you know how to do basic electrical testing ? Does your truck have manual or automatic trans mission ? Which transfer case does yours have ?

The NVG 263 transfer case features a three button shift control switch located on the instrument panel. When the ignition is in the RUN position, the transfer case shift control module (TCCM) starts monitoring the transfer case shift control switch to determine if the driver desires a new mode/gear position. At a single press of the transfer case shift control switch, the lamp of the new desired position begins flashing to inform the driver that the TCCM has received the request for a new mode/gear position. The lamp continues to flash until all shifting criteria has been met and the new mode/gear position has been engaged. Once the new mode/gear position is fully active, the switch indicator for the new position remains ON constantly. In the event that the TCCM can not or will not complete the shift, the indicator returns to the previously selected position; this is a Transfer Case Shift Control Switch Indicator Flashes, then Returns to Previous Mode condition.

The NVG 263 transfer case provides the driver with 4 manual mode/gear positions:
• 2HI - 2 Wheel Drive high range
• 4HI - 4 Wheel Drive high range
• 4LO - 4 Wheel Drive low range
• Neutral
Have it check for DTC'S - diagnostic trouble codes ?

DTC B0790
DTC B2725
DTC C0306
DTC C0327
DTC C0359
DTC C0379
DTC C0550

Your best bet would be take it to a qualified repair SHOP

Speedometer works when you hook a drill to transfer end but not when hooked up

There should be a small connector piece inside the housing that has a square end on it for the speedo cable to insert into on the t-case side. If this is missing/broken, the cable will not turn. You may also have a broken gear internally on the drive assembly. Remove the bolt holding the drive into the t-case and remove speedo gear for inspection

Contact your local transmission shop and see if this is a common issue. Most good shops will tell you. Also check with the local dealership parts department and see if there is a recall. Strange issue,.

Sounds like you broke a gear in the transfer case you will need a tranny shop to check it.

How can you tell or know if your tranfer case is bad/well i just purchase a new 4wd switch,because i thought that was the problem.but now it will be in some strange gears on its own and what so bad about i...

If your transfer case is bad (broken fork, gear, shaft or something) It could engage both the low and the high ratio gears at the same time. The vehicle will not move if this happens even if you put your foot in it and try to power out of it. Two ratios cannot be engaged at the same time. Just by your description, it sounds like something like a shift fork or shaft has broken loose from the selection gear and this is allowing the gear to slide on its own unchecked, randomly engaging and dissengaging ratios. I would have a trustworthy shop take a look right away. Any reputable shop could diagnos a transfer case problem within an hour. The shop should charge 1 hour diagnostic time to tell if it is bad and what needs to be done to correct it. If they need to take longer than that then have them tell you why, and it better be good.

Good luck, and if you have any further questions- just ask!

It sounds like you already have a Tooth Broken of of the Main 4X4 Gear inside the Transfer Case. Most Tranny Shops will rebuild these along with Tranny's. You might want to get a Rebuild or at least let them Find out Which Gear is Busted. Please Rate My Response! Thanks!

You Definately have a Gear Broken in the Transfer Case. It is not Easy to Rebuild. I would find a Tranny Shop and see if they could rebuild it for you. Tranny shops here in OKLAHOMA Do.
