I have the 242 t-case and when I shift into full time, I can hear and feel it shifting, but not when I just shift into part time. I know that there's a "shift sleeve" that physically moves into place allowing full time differentiation, and I'm sure that's what I'm hearing and feeling. My question is should I hear or feel anything when going into part time? I rarely use part time; I usually just skip on by with the shifter on my way to full time or low, so that's why I'm pretty unfamiliar with normal part time.
