What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I do have a transfer case, it's been 30-40k miles since its last service.

Don't laugh, do we have a front and rear differential? It just rear. I presume since I have 4wd I'd have both

Yes you have both but only the trans will "slip" either diff or the t-case will grind.

Yep. Does it do it in 4WD too?

Not gonna lie, I'm not sure. I can check when I get home, I'm currently violating social distance rules in an amusement park.

It seems like it catches it when it's close to shifting or downshifting and then I accelerate and it almost skips or has a slip when trying to get to the next gear.

Would it possibly be the differential? Would you feel the differential if something was off?

I think I know what your talking about. it's a weird shift like you depressed the accelerator right as it shifted from 1st to 2nd and it does this long soft shift. I have that happen once in a while.

Yeah I just had to take a step back when he didn't know how many diffs he had. I'll get over it lol...

Eh, I figured out awhile ago, not every guy is knowledgeable about cars--doesn't make him a bad guy tho. Really impresses me when a woman knows her stuff tho. Sexist--I know.

My last post I meant to say I figured I had both front and rear. I definitely don't hear or feel a grinding. I'll check the fluid with the YELLOW handle when I get home. Does it need to be cool? Lighter red is good, dark is bad correct?
