This is my first winter with a 1997 900SE Turbo Convertible. This morning was especially cold, and I was leaving the house early. I started the car and turned on the window defrosters. Let everything warm up until the ice melted. Put the car in drive, and it didn't move. Thought maybe the tire was jammed against the curb, so gave it some gas. It slowly inched forward. Weird. Figured it was just really cold, and proceeded slowly. After about 2 blocks, the 'check gear box' light came on. Turned around to head back home, and the 'check engine' light came on. Parked it. Looked in the owner's manual, which said to restart it - to reset the system - and see if the lights still come on. They did.
Is there anything I should try (in addition to checking fluid levels), before spending my Christmas cash at the local repair shop?
