Just replaced my transfer case fluid. I ordered 2 quarts because everywhere online I found said it’ll take under 2 quarts before it starts running out of the hole. I used a suction gun to put it in and of course some gets left in the length of the tube. But I figured I’d be fine as otherwise I spill…

The only recommended fluid for the transfer case is GM AutoTrak and 2 one liter bottles are used. Also, it is very important to change this fluid every 50K miles. Tester

Not quite 2 quarts went in but if 1/4" below fill hole is good then I should be ok. I did use Auto-Trak II (ACDelco branded, but everything I read says it’s the same as GM branded). I just bought the car with just under 80k on it and I’m fairly certain it was never done before. Will probably do it …

I had mine done at 80k and 165k, still looked fresh bud said, he is a gm mehanic that works on the side, At 165k also had front and rear differential fluid change. Is there a way you can stick something, bent straw or whatever to make sure it is near the top? Sure you got the right nuts? For less th…

I used a bent twist tie to check it and it was 1/4" lower at most. I was sure I had the right plug in the holes but now I’m second guessing myself. Are they different? I was sure I put them back in correctly because the drain plug fell into the pan and I left it there until I was ready to put it in…

If they’re one liter bottles and you put both in, you’re good to go. Tester

The fluid that came out was translucent green. I assume that’s normal. Didn’t smell burnt or anything - no shavings. I didn’t measure it but before I changed it when I checked it, it was 1-1.5" lower than the fill. No signs of any leaking. I have read other posts about them being undefiled from the …

I’m only finding one part number for transfer case plug (89059626) and most places list it as a fill plug (others don’t specify) with no mention of also being for drain but they don’t list a separate drain number. Rockauto lists this part number as a drain plug but they have no fill plug listed. So …

Don’t overthink it too much. 1/4” below the hole or running out of the hole is only 1/4” difference and the transfer case doesn’t care. :stuck_out_tongue_winking_eye: I always fill differentials until fluid seeps out of the fill hole. My 05 Sierra, I found online that you’re supposed to fill the re…

2 quarts should do it. 1/4 below the fill hole is fine.
