My 1992 Ford Ranger 4x4 4cyl 5-spd has a clutch issue. I have had a small leak in my clutch system which requires me to refill it every 3-4 months. Today after about a 120 mile trip, I pulled up to a stop light and noticed there was no clutch pedal pressure when I pushed it...and the truck stalled before I could pull it into neutral. The only way to take off is to put the truck into 1st gear and crank it, but that is just to move it...it won't let you shift into any other gears. The clutch has only 17K miles on it...could this just be my slave cylinder? Thanks for any help. I depend on this truck to get me to work!
