    NP246 compatibility?

    Hi, Could anyone chime in on transfer case compatibility? My TC is the one with the clean decal the one I'm looking to replace it is the dirty one. I asked the seller for a clearer picture but in the main time does anyone know if the two are interchangeable? According to the seller it is from a...

    Has anyone managed to do a DIY cabin filter?

    I Have a 98 Suburban that I originally bought for driving on forest service roads. What I totally didn't think about is the lack of cabin filter. The roads I'm driving are absolutely horrendous when it comes to dust. The entire interior and my stuff is constantly covered in dust. Has anyone...

    4L60E rebuild. What did I get myself into...? :P

    It looks like I'm in for an adventure. Having to fork over 3.5k for a shop to replace the transmission was just a bit too expensive as this is not a showroom piece, its a bush beater and occasionally daily driver. The other option is to buy a used one for $500-700 of questionable history and...

    NP246 is it possible to reassemble it wrong? Problem solved!!!

    The quick rundown; I pulled the transfer case as the bearings were shot. I got the rebuild kit and went to work. I put the TC in first and tried to put the encoder on after as not to rush damaging it while putting it in, that's when the trouble started. The notch on the TC did not align whit...

    Its probably a weird question but here it goes... I have a bunch of Penzoil Dextron 3 ATF that is probably around 15 years old. Its leftover from a project that never happened as I sold that car. Its just sitting in the garage ever since. It was stored in a cool garage, seals intact. I just...

    Help finding the correct filter and seal?

    I've just took out the transfer case as it had a broken bearing and needs rebuilding. My thread about it. Since I put the front wheels on a ramp to get better access, lots of transmission fluid came out therefore this would be a perfect time to change the ATF. I am looking at rockauto and they...

    Noise in my transfer case? 1998 K1500 Suburban

    I’ve been hearing a weird metallic kinking kind of sound lately when I’m driving the car a low speeds. I couldn’t figure out where it comes from. Last weekend I put the rear on jacks to check the drum brakes and I finally found the source of the noise. As I turn the drive shaft there is this...
