lately my transmission feels like it is slipping it is a 5 speed behind a 4.9l which is i believe an m5od. if it is slipping would changing the clutch fix it along with new fluids?

 

Manual transmissions do not slip. If anything is slipping it is the clutch. If you change it, be sure to replace the &$#@%^* annular slave cylinder while you're in there; it's not a job you want to do twice.

Changing the tranny fluids is not necessary but it's not a bad idea either. Use a synthetic ATF or one of the ATF replacements designed for manual trannies like Royal Purple Synchromax or Redline MTL. While you've got the tranny out, inspect the plugs at the top rear of the tranny, right below the shift tower. If they show any cracking of tearing, replace them.

 

The clutch is the culprit if a manual feels like it's slipping, no question there. However, it could be the actual clutch/pressure plate, or it could be the slave cylinder leaking or having leaky seals, not getting enough pressure to the clutch.

The fluid is a toss up. Change it if you want, but that won't cause slipping. It can't hurt anything.

 

No, it can't. The slave doesn't ENgage the clutch - it DISengages it.Actually, those little Mazda boxes are VERY sensitive to fluid level & quality. Definitely change it, if it hasn't been in the last ~30Kmi.

 

Yep, my bad there, got things switched up. Likely pressure plate fingers are worn out, or the clutch plate surface is just beat. Either way, replace the whole thing while you're in there.

 

are there any special tools i would need to swap in a new clutch or just the basics? thanks for all your help probably order a centerforce by friday!!!!

 

No special tools, but bleeding the clutch slave is tricky.

 

thanks for the help i ordered a centerforce stage 2 this afternoon should be here by tuesday

 

Are you going to replace the slave cylinder as well?

 

every time you pull the tranie put a new pilot bearing in. it is cheep and one of the major causes of trainsmition failure.

A bad slave cylinder can't damage the trans. In fact, a GOOD slave is more likely to do damage - they were known to fracture the front of the transmission on some applications.

But I'd still replace it. They go out all the time, and you don't want to have to do all that work again for a cheap part.

 

thanks for all the help but i found out the slave cylinder was replaced a few months ago along with the throwout bearing not sure about the pilot bearing though is this near the the clutch or inside the transmission casing

 

the pilot bearing is in the flywheel in front of the clutch, the nose of the trainsmition input shaft fits into it. they give you this bearing with any good clutch kit.

The pilot bearing is actually in the back end of the crankshaft.

 

if you get a good clutch kit it will have everything you need even a clutch alignment tool. just remember to surface the flywheel and clean everything with brake clean before yo put it together. and dont forget to toque everything.
