1994 Ford F-150 Clutch Problems

Im having a clutch issue in my '94 F150. Yesterday it was colder than normal and I was having trouble getting into first gear (from sitting still or down-shifting), and into reverse. It took considerable more effort than normal. Today, same problem, but now there is way less pressure required to depress my clutch pedal, and the clutch is starting to slip. Seems to me like something that can adjust the tension on the pedal has worked itself lose maybe? Maybe its a hydraulic fluid/cylinder problem? I hope I don't need a whole new clutch assembly!
Do you
have the same problem?

Start by checking the clutch master cylinder if its low in fluid if so fill it and then bleed the system. Also check the transmission gear oil level


Remove slave cylinder from transmission bellhousing. Using a 3/32" diameter punch, remove pin that holds hydraulic line in slave cylinder. Remove hydraulic line from slave cylinder.
Place hydraulic line into container for waste fluid. Hold slave cylinder so hydraulic line port is at highest point. Fill slave cylinder through hydraulic line port with DOT 3 brake fluid. Gently push on slave cylinder push rod to expel all air.
When all air has been expelled, install slave cylinder. Remove clutch master cylinder reservoir cap. While maintaining fluid level in reservoir, observe hydraulic line until all air has been expelled and a steady stream of fluid is flowing.
Install reservoir cap. Install hydraulic line and retaining pin. Top off brake fluid. With transmission in Neutral and parking brake set, start vehicle. Shift vehicle into Reverse. If gears grind, check for air in system. Repeat bleeding procedure if necessary. If no air is found and gears grind, clutch components may be defective or worn out.

Using Disconnect Tool (T88T-70522-A), disconnect coupling at transmission by lightly tugging on clutch tube while sliding White plastic sleeve toward slave cylinder. See Fig. 5. Clean area around reservoir cap. Fill reservoir with DOT 3 brake fluid. Using hand pressure, apply 10-15 pounds to clutch pedal. If pedal is hard, go to step 3). If pedal is spongy, go to next step.
Using a screwdriver, open valve of male coupling. Slowly depress clutch pedal to floor and hold. Remove screwdriver to close valve, and release clutch pedal. Ensuring reservoir is full, repeat step.
Close reservoir and reconnect coupling. Rapidly depress clutch pedal 5-10 times, wait 1-3 minutes, then repeat procedure 3 more times. Place hose on bleeder screw to prevent brake fluid from entering bellhousing. Loosen bleeder screw and maintain fluid level in reservoir.
Fluid and bubbles will flow from hose attached to slave cylinder bleeder screw. Close bleeder screw when fluid stream is free of air bubbles. Ensure fluid level is correct and install reservoir cap.
Place light pressure on clutch pedal and open bleeder screw. Maintain pressure until pedal contacts floor. Close bleeder screw while pedal is fully depressed. DO NOT allow pedal to return before bleeder screw is fully closed. Recheck fluid level.
Test system operation by starting vehicle, depressing clutch and placing gearshift in Reverse. No grinding should be heard or felt when clutch pedal is within 1/2" (13 mm) of floor. If noise is heard, check for air in system. Repeat bleeding procedure if necessary


NOTE:Clutches are a single, dry disc type. Adjustment for wear is not possible. Clutch is actuated through hydraulic master cylinder and slave cylinder, and is self-adjusting.
