    Question Changing out the Transfer Case Fluid

    i have a 97 Yukon 2dr with the electronic push button 4x4. First does anybody know which transfer case model it was for that year/model?

    The main question i had was how would i go about changing the transfer case fluid and what would i use and how to do it? Never done it before.

    Auto Trak II from the dealer for the push button case. It's the 243C transfer case. It has the same drain and fill plugs on the back side of the case as a 241C. Just take off the bottom one and loosen the top and when it's empty put the bottom plug back in and fill it to the level of top plug.

    X2+++ Also a pump oil can or a tube that screws onto the bottle makes filling it back up easy

    '97 wouldn't have auto trak IIRC just a standard NP243

    I bought a syringe type of transfer pump, it works great, the hoses are long enough so you dont have to be under the truck. Great for diffs, trannies and t-cases. Under 20 bucks at the local Parts Source.

    Negative on the fluid. Only the 246 needs that expensive blue dealer only stuff.

    The 243 can just be filled with 4qts of ATF DXIII+

    Cool, I thought all the clutch pack equipped t cases took the auto trak. That should save you some money.

    243 has no clutches, hence no A-trak II. It's just an E-shift 241.

    Actually it does have a high/low clutch pack. But it looks like a really simple mechanism to soften the shock of the high low shift.

    Reference?

    There's zero friction clutch parts in a 243 I've ever seen.
