My 99 Legacy Wagon has 82,000 miles on it. When the weather is 50 degrees or cooler and the car has been sitting overnight, I can't engage the automatice gear shift. The car has to warm up for 10 minutes before I can shift gears. Any solutions?

Could be a dirty filter.... try a fluid & filter change.

 

Or a sticky valvebody, not much you can do other than a rebuild, but... I've had some luck with the auto trans snake oil, Lucas brand. Also, try running up the RPMs in park or neutral to around 4000 for 4 or 5 seconds (builds pressure in the pump), then idle down BEFORE you shift into gear.

 

Good Luck

The valvebody on the 3-speed isn't much of a problem to take apart and clean the passages. No experience with the 4-speed (yet), but can't imagine it is much more difficult.

 

I would echo All-talk, change the fluid... not sure if the 4EAT has a filter... the 3AT doesn't.
