Clutch/Transmission rattle

Ok I apologize off the top if this is in a thread already but i didn't see it when I did a search. So I have 03 Mach with total mileage right at 203k. I bought the car at 180k and was informed that 20k prior the engine, transmission, clutch had all been rebuilt to ford spec. With thew interior being as flawless as it is and how well the car ran you would never guess that it could be over 30k. So everything has been great other than a couple minor issues where all of a sudden an O2 sensor went bad, then a check engine light for a MAF, and one for an idle air control valve, and sudden appearance of engine noise through the radio.

The issue that has me and most important is a strange rattling that I assume is transmission/clutch related. Every time that I press the clutch to the floor I get a rattling sound. It's loudest when first operating the car and steadily goes away the more it's driven and disappears almost completely to completely at times after a bit of driving. Once I let off the clutch it completely disappears. It is no worse or no better if the shifter is in neutral or any other gear.. Has anyone had this same issue and knows what it is or does anyone have any ideas of what it most likely is?

Re: Clutch/Transmission rattle

I bet the previous owner didn't put in a new clutch lever and pivot ball stud when they did the clutch job. The pivot ball could be worn and the lever is bouncing back and forth on it. That's my guess!

Re: Clutch/Transmission rattle

Sounds like a throw out bearing.

They probably used one that came with a clutch kit. The problem is that the cable cluches have to have a tob that is rated for constant pressure or else after a while they begin to burn up.

Re: Clutch/Transmission rattle

I'm having a similar issue with my T-56 install. But this one sounds like a rod is knocking but only with the clutch out. It comes and goes. Is more prominent when the transmission is warm. I've even had the A/C compressor cause a hellatious noise to come from the shifter. Looks like I'll have to be pulling that sucker again soon.

Re: Clutch/Transmission rattle

Thanks guys for the replies and thoughts. New progressing issues now with it. Last week the rattle disappeared after steadily getting worse. It was replaced by a minor squeak/moan (both of which aren't good descriptors as the sound lies somewhere in between). Sound was primarily as I made the transition releasing the clutch and giving it gas. Then on the way to work Monday morning there were a couple instances i was locked out of a gear, i think primarily 2nd and 3rd, a couple times. It took a few seconds of holding in the clutch and letting it throttle down and a few attempts before it would slide in gear. Then the kicker Monday evening i go to throw it in reverse and leave work and ****ing big time grind. Repeatedly!!! I got it to go one time throwing it into reverse kind of harshly and it grinding then locking in. It continued to do so every time I tried reverse. I had to start shutting the car off then putting it in reverse then starting back up. At the end of the night I tried a couple suggestions of pumping the clutch a few times then trying reverse and it did go into reverse albeit it a little roughly, but without any grinding. I also tried the 1st to reverse method and that seemed to work fine. Then the rest of the week not one bit of trouble out of it. Until tonight then grinding into reverse again. Tried the pump method and still grinding trying to get it in. I went 1st to reverse and that got me into reverse albeit a little clunky again. I've intermittently had reverse grind since I bought it 2 years ago but I understand that's just the deal with no synchro for reverse. Multiple times over the last 2 years i would pull back on the stick to reverse and it felt locked out until I would slowly ease out the clutch and it would drop into reverse.

Anyway I was thinking a master/slave hydraulic issue after the pump method worked but then when it didn't this time I don't think it's that. I've always thought the release bearing was the rattle especially being that it's exactly matching up with the symptoms given in the Ford Mustang repair manual that Ford uses, the 5000 page one. I think it progressed to maybe a warped pressure plate or something causing clutch drag. Haven't tried to test for it in a parking lot anywhere being that I think where I live the police would be up my *** in a heartbeat with the exhaust on that car and it revving up to 7200

So, sorry about the lengthy reply, but anyone have any additional thoughts with the extra symptoms listed? I'm thinking I'm going to replace the clutch and plate and bearings and all that jazz here shortly. Hopefully nothing else is damaged other than that. Are there any step by steps with pics for that or videos floating around out there?

For future reference aftermarket cables generally don't last as long as the stockers. My 04 came with am adjustable cable and the outer sheath started to fray. I put a stock style in and haven't had an issue since.

Ahhh ok, good to know. Since I have it in already I guess I'll just leave it go for now and make sure to include it in my weekly checks instead of monthly or quarterly and if something goes wrong then I'll replace it with stock then. Just to clear up any confusion I might have, you are strictly talking about the cable only right? Not saying to get rid of the quadrant and firewall adjuster to go back to the self adjusting right?

Re: Clutch/Transmission rattle

Yes you can have a quadrant and adjuster. The adjustable cables can be hit and miss. Mine works perfectly but i was lucky
