    Swap NP243 electric to NP241 Manual shift

    Hi Everyone, I see a lot of discussions closely related to the issue I am having but nothing direct with the precise data I need. I have a 1998 k2500 Silverado with 7.4l 4L80E transmission. It came stock with the NP243 transfer case. It shattered, poor maintenance before my time. I purchased...

    4Wd Fuse Blowing, Tried Every Fix I Know

    Hello, on my 1993 K1500 the 4wd fuse will not stop blowing. I've read every post I could find on here and other websites, and nothing will do the trick. I was hoping that someone would have a fix before I spend another $150 on a Posi-Lok after spending $150 on a new electric actuator and t-case...

    4X4 dash switch intermittent.

    Hello guys, I have an appeal to all of your collective experience. I have an issue with my '99 K2500 (cross-over year truck. Think '98 GMT400). The 4 wheel drive switch only works when it feels like it. Often there are no lights at all. Sometimes it won't even operate the 4-wheel drive...

    NP 241C

    Running into a little problem. Recently when when I shift from drive/reverse into park (on any kind of incline, causing the truck to roll a tad bit forward or backwards) there's a god awful "popping" noise coming from what I believe to be the transfer case and the truck proceeds to hop in what...

    NP241 Strength?

    I have a np241 out of an 89 GMC. I'm wondering how strong it is for what abuse I'm going to use it for. The truck has a 350 that I plan on putting a cam, heads, headers, and intake on, so I'm hoping for around 350-400 crank horsepower or maybe even more. I know I'm going to have to build the...

    Transfercase question VSS

    I installed my 1994 k2500 nv4500 transmission and transfercase in my 1997 k3500. The speedo doesn’t work. Should I get one for a 1997 or should it make no difference and maybe the 1994 speed sensor is bad?

    4x4 Wiring?

    20200825_200557 by JT_Dubz posted Aug 25, 2020 at 8:06 PM My first post here on this forum, or any forum for that matter. I recently bought a 98 k1500 z71 (my first chevy truck) off a fella, and he told me the 4x4 wasn't working because of a "wiring issue". I searched around under the truck...

    Transfer Case Troubles on '94 K1500

    Okay, so I'm fairly new to working on my truck and had the 4x4 go out on me. When I shift into 4wd, it grinds the hell out of itself and won't lock the front axles. I was told it could be the actuator, and I'm currently strapped for cash. Any advice will help.

    Truck stuck in neutral after 4x4 is engaged (97 1500 5.7l)

    I have the electronic push button 4x4. Any time I press the button to engage 4wd the transfer case goes into neutral and stays there, leaving me stranded. If you try and change gears it makes grinding sound. Usually, I stand around and reset the battery a few times (truck wont start in neutral)...

    4x4 Electrical - no power at T-case Switch

    I recently got a 1997 Chevrolet Silverado 4x4 from my uncle as he never used it anyways. I ran into a problem with the 4x4 not engaging, the selector switch flashes, times out and returns to 2wd. However, there is a noise in the transfer case that I believe is the motor working. I switched out...
