My clutch slips when I shift up, resulting in a loss of power for a moment until it engages the gear. It’s especially noticeable from 1st to 2nd gear. I have a 1994 Nissan Sentra. I’ve read about adjusting the clutch cable, and I know how to adjust, but nobody is clear on which way to adjust. Do I tighten or loosen the cable? I just need to buy some time before I get the whole clutch replaced.
