I'm getting ready to change the fluids in the auto trans, transfer case, and both diffs, however when looking for the transfer case fluid I noticed some auto stores offer specific transfer case fluid when the vehicle specs call for ATF+4. Both are synthetic fluids. So what is the difference, and is using specific transfer case fluid worth it?
