or the pressure pate is failing. Either way the transmission has to come out so I would replace it all. I used everything from Luk : pre-bled master cylinder with hose, slave cylinder, flywheel and clutch assembly.

Thanks, that's good advice, I believe I need to change seals also, so it may not work for me but I will sure try that, I am having problems finding the right parts, so i guess I need to take things apart and hope for part numbers

Thanks for your help

What seals? What may not work for you? How are you having trouble finding parts? I highly doubt that you are going to find part numbers.

I guessed at the engine in your truck and came up with 15 clutch kits on RockAuto’s website.

Honestly I haven't looked at seals yet, but am guessing there is seals between gearbox and engine, she is leaking a bit ...I will have another look

I am not in the US, but live off grid in The Yucatan Peninsula in Mexico, so its not as easy as Rock Auto, I have used them before, but shipping to here is crazy

As far as I understand it there are different diameters of the clutch plates, I hope to start taking things apart today or tomorrow

Thanks for your advice and comments, I appreciate it

That gear **** looks different than mine, but I guess I will go with door sticker and it says Mazda, I do plan to change everything while I am in there anyways

Thanks

As an added bonus, if you get all-thread in i think 7/16-14 thread pitch ( bell housing bolt size) and about 7 to 9 inches long, and put matching nuts ( one on each piece of all-thread) at the firewall end. Then remove a bellhousing bolt (one on either side of the transmission). Thread in the all-thread a decent amount. You can then remove the other bolts and slide the transmission back enough to replace parts while using the jack to support the weight. Then slide the transmission back into place easily as the all-thread guides it back to the engine. I do this for just about every vehicle that needs clutch or torque converter work.


Yep yep, make studs when I did with that big ZF and it makes life far easier.

Also pop the thing into 4th so you can rotate the output shaft upon reinstall, this is so you can rotate the input shaft easily to line up with the pressure plate.

There are some rubber plugs on the top, may as well replace them. The name slips my mind currently, someone will chime in. Consider new shifter bushings too and 100% do the pedal box units.

What engine? There are seals but what is it leaking and where: oil or automatic transmission fluid?

Even if you don’t buy from them because shipping is cost prohibitive that website will show you part numbers that you can use at a local parts store.

10” or 11” I believe that you can use either one but I would not install a 10” when it had an 11” clutch.

Because that is a shift **** for a 4 speed with overdrive and you have a 5 speed with overdrive.

I would have never guessed the all thread was strong enough to hold the front up.. this will make me more apt to swap my own clutch when the time comes. You can do the same and have room to change rear main seal?

Thanks, its a 4.9 , and I believe all seals are leaking a bit

You are correct, I do use Rock Auto for parts numbers from time to time its a great help

at least I can measure the one that's in there now

Gear ****.,...I completely over looked that



Thanks
