hello all ok here is what i have a 93 F150 5.0 5speed 4x4 w/175000 miles i have two problems first is the tranny is real noisy only quiet in forth gear is there anything i can ad to the fluid to quiet it down some or is the tranny just shot? second the po said he put a new clutch in it not sure if he actually did but i have to push clutch pedal to the floor as far as i can to get it in first gear but if i let off like an inch or two its engaged could the master or slave cylinder be bad?

 

the tranny, i have no idea. the clutch thing sounds like it just needs adjusted. look under the dash at it, on the one i did, you just screw the shaft down so its shorter and engages sooner.

 

Have you checked the condition and level of the Mercon ATF fluid? The noise you are talking about... Is there rough engagement changing gears (synchronizers) and/or do you only hear sounds while in one gear? What does it sound like, how loud is it? Make sure the fluid doesn't look dark and there is no sign of the trans leaking underneath. Improper shifter linkage adjustment could give problems as well, does each synchronizer (gear) engage smoothly with the engine off/clutch in? What about when it's running?



I think you have the Mazda M50D 5-speed transmission if i'm not mistaken.

 

as for the fluid looks good not dark it makes the noise in 1 2 3 and 5th the sound is like a whining and and gets louder as you accelerate appears to shift smooth running or off no binding if linkage is adjustable how would i go about that?

 

 

The clutch is not adjustable. Plenty of other good suggestions though.

 

Gears 1-3 are underdriven, 4th is direct drive and 5th is overdriven. Interesting how the only gear thats 1:1 is not whining...

If all gears were whining, it could be the output shaft bearings but since 4th is fine, that is ruled out.

 

i didnt think you could adjust the clutch since its hydraulic so which would it be master or slave cylinder?

 

I'd say bleeding the master cylinder would be an "adjustment," so to speak.

 

that sucks, i know on my friends you could adjust the rods length that goes from the pedal to the cylinder, ohwell.
