I'm a new Xterra owner, just bought it in August and it needed its 90k service, and i'm a strong believer in fresh fluids. I had my trans flushed as part of the service, along with the transfer case, diffs, and engine oil. All is good except for this little slippage that happens every now and again when i'm turning and accelerating, and when its slowing down to a near crawl at stop light. It happens pretty rarely and I tried to see if I could force it and I couldn't. Is this normal because of viscosity differences and it's getting "used" to the new fluid, or should I take it back to the shop to see whats going on.
