My Zf Just Sh*t Its Self

[turbotrana]

I change transmission oil and diff oil every 40000km. I have diffs and gearboxes that have done 450000km with no noise and no issues.

The diffs that you hear whining (I have heard heaps of whiny Mercedes and BMW diffs) are the ones where the diff oil is never changed. The manufacturers could not care less if you change the oils because a majority of cars will be out of waranty by the time it fails

Make no mistake these are a good transmission and treated right will last a lot longer than 100K. Even at Higher HP

Ive had some 30 in pieces helping mates modify them to handle the extra HP and some of those have done 100k before we opened them up.

My own personal transmission I used genuine Oil at first and had it out 3 times in 15k but since I repaired it last time and started using TransmaxZ I have done 40k and not touched it. (375rwks)

Just this week I helped Simon from extreme replace his input shaft on his Blown FG with over 500rwks and the oils and discs were in top condition since we modded it.

The only way you can achieve some sort of longevity and reliability is with good quality CLEAN oil.

To state that

the clutch material gets suspended in the fluid and alters the viscosity and friction profile

Baffles me somewhat!!!

Ask yourself this question:

What sort of wear should we expect then when the transmission is new with new oil?

The above quote is like saying the transmission will wear out rapidly when NEW until its worn out at which time the the clutch material gets suspended in the fluid and alters the viscosity and friction profile.

Its 2009 and most oil manufacturers are quite capable of making oil that is of the correct viscosity and friction profile from new.. It doesn't get better with age sorry! Maybe too Much wine being consumed which does get better with age ahhahahahah

You're right Gramps, makes no sense whatsoever.

The diffs that you hear whining (I have heard heaps of whiny Mercedes and BMW diffs) are the ones where the diff oil is never changed.

...except for ford diffs that whine 200km after being replaced.

Read the PDF attached to F6 Utes post. How farkin lazy are people around here

It's in this farking thread

Don't get upset mate

I'm starting to lean towards your thinking F6 ,so I will get it serviced so you definatly think the trans max is a better oil , on a side note are you up for rebuilding mine if I do kill it

cheers paul

Transmax is one oil that is better than factory spec oil but there are other oils that people use with good results like Penrite. I have never used Penrite personally but I believe its good.

No matter what oil you use you just need to make sure its meets or exceeds the ZF spec and if it does technically ZF cant refuse warranty. Although if your vehicle is STD I cant imagine you would have a warranty problem with a ZF during its 3 year warranty period

Without beefing up the packs I think people will continue to have problems. I wont build yours as I don't build them for a living and only help others and supervise them to build them themselves. I rather see people learn and save a dollar at the same time.

I used Penrite oil done about 500km already best thing I have done box feels heaps better wish I change the oil a year ago like I planned but just didnt get around to it cost me 249 bucks for a 20 litre drum

any one who wants to change theres in the wollongong area pm me and ill give you the name and details of who done mine

cheers trev

Well after my misadventure earlier in the week mine looks like its cactus so out it comes out early this week coming & over to the boys on the big west to make me a strong one so I can get back on the road & start my big build up. Cant blame the thing. Has put up with over 50 track passes & 400kw for a while. After my last change with transmax z it felt great but I think with track use like I have its needed every 5000klm to keep it up to scratch.

mm well that's where I'm back on my own , and I think I will stick with the guys that have been useing them a lot longer than the ford camp and take my chances

I don't want a drag box just a reliable every day .

and even though you believe your theory there has been more than one case on here that have had issues with useing trans max

Has there actually been a case where tansmax z can be blamed for a zf failure??? Wouldnt think so.
