With no lead up to the problem, the car would not go into gear. Replaced the master/slave cylinder and had the car towed to a local shop approximately 5 miles away. Cost was $558. Did I get ripped off?
Slave cylinder replaced prior to my purchase of the vehicle.
The clutch had started feeling funny over a period of a couple of months. One day I lost the ability to shift altogether. It was fixed temporarily by adding gear oil. Soon after that I had to have the clutch master and slave cylinders replaced. The problem is resolved for now, but the car still is reluctant to shift into first, especially when it is cold.
