I have a 1994 F-150 and when I shift, it is real rough. It doesn't grind, but it just doesn't feel right. I had to have the slave cylinder replaced in Janruary and I don't know whether the new one is going bad or what. I don't know whether I need to add clutch fluid or what the problem is. Als, where do I check the clutch fluid? Is it next to the brake fluid? If anyone could help me out I would appreciate it.
The clutch fluid reservoir should be close to the brake fluid reservoir.
As for hard shifting, do you mean it takes a bit of effort to move your shifter? If so, maybe check your trans fluid level. Could be time for a fluid change anyway. Drain it an fill it with ATF.
I had this problem on a 94 Explorer and it turned out to be contaminated (water) fluid in the system. The clutch used brake fluid from the master cylinder reservoir. We had the fluid replaced and everything was OK.
To the reply about changing the trans fluid. I tried to get the plug out to check, but the thing must be rusted shut. I put some WD-40 on it, but it is tight. Is there anything to suggest? Also, I have two places that have "brake fluid" caps. Which one is the clutch fluid? I've never changed my trans fluid, is it just like an oil change or do you have to use an air pump?
The clutch reservoir is just a little higher and closer to the engine. It has a plastic line on it. The brake has 2 steel lines.
As far as the oil change, pretty straight forward. Assuming you have the M5OD, there are 2 plugs. Both on the L/H side of the tranny. One on the side bottom and the other on the side top. Remove the top first to let tranny vent and drain faster. Reinstall bottom and service tranny with ATF at top plug until fluid comes out. Not sure of capacity at this moment but should be between 4-5 quarts.
I don't know if a clutch that doesn't release completely can be hard to shift without grinding, but I would have someone press the clutch pedal, and look to see how far the clutch fork moves. It should move around half-inch. Also pull of inspection plate on bell housing, and see if clutch is being completely released. I know Ford had a problem with the firewall flexing (Ford repair kit available), because of a structural crack on the firewall. Also, the nylon bushings that go on the clutch linkage have caused problems, as well. In addition, the clutch master cylinder could be going out or air is in the system.
Yea, when I shift it doesn't grind, and I don't have trouble getting it into gear, but when I do pop it in, especially 2nd and 3rd, it is not as smooth as when I go into 4th and 5th. It's almost like rubbing your teeth together, but on a larger scale.
What's the mileage on the truck. Almost sounds like the syncro's for the 2nd and 3rd gears if 4th and 5th is smooth. They're made of brass and wear faster the the actual steel gears.
Last night I checked the transmission fluid and it was full. I opened the fill plug and the fluid game dribbiling out. I also checked and the clutch fluid reservour and it is full. I don't know what the problem could be.
I mentioned before in a previous post to you that over time firewalls mounted with hydraulic clutch resevoirs crack and flex when you depress the clutch. Instead of pushing the pushrod on the clutch fork your force is being concentrated on the firewall. Check that. Also check all the bushings involved in the clutch pedal linkage. Where-ever you've got slop is where your losing force that should be going to the clutch. Hope this helps.
