I towed my 300d for about 400 miles last week on a dolly with the car in neutral and when I got there reverse would not work but the forward gears did, it would go in and move about 10 inches then stop like it was binding up , I know it was stupid to tow it but can it be fixed or should it be replaced I have another unit from a 92 300d any coments would be nice even funny ones thanks
