EYEDOCK

This is a werid one. I have 2001 3.2 CL-S. with automatic transmission. This only happens when it is cold out and the car is parked outside of course. It is really hard to shift gears (even after the car is warmed up and was moving for a while). By shifting gears I mean taking it from park and putting it in reverse or into drive. The shifter cable feels really tight. When its warm or the car was parked in the garage it does not happen. Tranny was already rebuilt and does not act up. I wonder if it is just the cable that needs to be replaced.
