Came out this morning to head off to work. Start my 99.5 Golf mk4 5-spd and she won't go into 1st, 2nd, or 3rd, but will freely slide into 4th, and 5th. I had the car out a few days ago after I changed the brakes and drove it around for 20 mins, before parking it in my garage and only used it until now. The only think I can think of that has changed since then is that it has dipped below freezing temperatures where I live since the weekend. I let the car idle for a few mins and still the shifter won't go into 1st -3rd gear. Any ideas?
