Changed oil in my gearbox... found this:





It was prob the first gearbox oil change in 55k miles that this car covered.

Is that more or less normal or am I ****ed?

 

Wow, first post on this subject I've seen personally. Hopefully someone with some experience chimes in for you.

How does it feel when you drive it through the gears? Good luck!

Absolutely ZERO gearchange issues.

Car drives through all gears perfectly, it just makes that noise that I mentioned in my other thread, like bad bearing/whine kind of noise under load.

Will have the car checked on tuesday, hope it is nothing serious.

Maybe a bearing in the box died? Would it spit metal into oil like that so that magnet could collect it?

 

slight miss engagement will cause this.. it would be more unlikely to pull the drain plug and not see any shards of metal from the syncros

therefore - dont even worry about it

if you want to change more fluids, get that front diff fluid drained too.. you can use the gear oil on that too.

 

Took care of the diff fluid today as well, thanks for the tip.

Happy to see that some metal does not neccessarily mean a transmission disaster.

I still have to figure out that whine/bad bearing noise from the back, it drives me crazy and gets louder everyday.

Is there a chance that a flywheel on its way out could cause such noise under load in higher gears (3rd gear +) ? i do have the flywheel rattle when I kill the engine without pushing the clutch first.

When I drive, that whining noise is not there in 1st, almost non audible in 2nd and then starting at 3rd it gets loud enough for me to not enjoy the ride anymore. It is not there in neutral or when in gear, not accelerating.

 

Seems normal to me; thats just normal wear & tear from synchros and so on...

 

100% normal

 

I just had my gear oil changed at a little over 50k and the mechanic said it has some small metal bit on it like yours. Tranny seems fine...

 

Since we are discussing trannies, I am getting a clutch job/LWFW and we are swaping the fluid. Besides the tranny, i should also swap teh flui in the front diff? Anywhere else?

Delvac 75w90 for everything OR some other gear oil?

thanks

 

Bearings(aluminum) and synchros (brass) are not usually steel, so they won't stick to a magnet...unless you have aftermarket synchros or GT2 synchros. That is probably gear shavings....

 

I just changed gearbox fluid on a 996tt with 30k and it had just a small amount of soft metallic fuzz on the drain plug magnet. I would say less than a 1/4 of what is shown in your pics.

 

Mobilube PTX or Shell transaxle, both Porsche specific and approved gearbox fluids only sold through Porsche dealers.
