I have a 1993 Oldsmobile 88 Royale that starts just fine, but requires me to heat it up for as long as 10 to 25 minutes before it will shift into gear from park. After that, it drives just fine. This is required every time I start the car up, if it's been turned off for longer than a couple of hours.

I had someone suggest that it might be the sensor, while someone else said it might be the transmission. Any suggestions on what it might be would be great. Thanks.

If system does not perform as described, unlock park lock cable adjuster (button up). See Fig. 11 . Move cable connector nose rearward until key can be removed from ignition.
