Zf Flaring When Cold

[Evil F6]

Because the viscoity of the oil is different. This causes the clutchs to absorb the new oil and alters the characteristics of the friction material. As the computer is calibrated in micro seconds for shift quality to suit the correct oil, the use of other oil will cause slippage of the clutches(flaring), harsh shifting which can lead to transmission failure. Even after an expensive oil flush with the correct oil it cannot guarantee the reversal of the problem.

Well my car is way beyond getting warranty. But you're the first person to raise any issues about the Castrol Transmax I've come across.

I concur, there has been some considerable feedback supporting transmax-Z v the rip of Fraud sh*t.

All in Hi-po applications. That said there are no definitive experts on the ZF and maintenance or rebuilds.

Fraud would certainly be last in the cue.Farking incompetent with all models of the 6T engine and driveline.

Wouldn't trust those chimps to fetch pies without farking it up and blaming the poor ole consumer.

Don't start me, I have a list a mile long , in addition to all the quality work performed on members cars

I have a brother who is an automatic service specialist at a major Ford dealership. He a completed training ZF training courses. He states that the ZF is a very good gearbox with rarely any problems except when people change the type of oil they use in the gearboxes. They do not require oil change for the life of the gearbox(150000klm).

Like I said if you want a good service life from your gearbox do not use anything other than the recommened oil. If the so called experts say there are other oils that can be used ask them for a written guarantee that the new oil won't do any damage to the gearbox. I bet they wont. Phone ZF and talk to them, they are experts, not independant auto shops , tuning shops etc.

The computer that is built into the valve body has every bit of information stored in it since the car left the dealers showroom. It can tell the ZF tech every gearchange, torque through the gearbox and even your driving style. If you make a warranty claim they can download the info from computer in the gearbox and they can verify it or reject from this information.

These gearboxes are a couple levels above anything else in technology and expensive.

Well maybe you're right, as I had no issues before changing oil to transmax. Still I would never leave the oil in for 150000km even if stock.

What does filings in the oil indicate. What's wearing?

[Buf-Phoon]

In modified cars , pan and oil changes should be part of the service component albeit expensive.

Sealed for life is just BS. Debate remains who knows better ?

A highly credentialed tranny shop or the chimps at Fraud. You break em' they can't fix em.

NFI. Fraud say it's right mate, tuner says we'll do a service on it.

Second to third downshifts sorted in manual mode .....fixed tuner, fraud she'll be right for 150ks

Fraud...........3 dealers farking useless. Just a cue of pie fetchers waiting to flog

the sh*t out of your car. Sorry but its true.

On my previous Phoon had one dealer that did pick ups for servicing , got the car back with a

AP twin plate slipping like a bastard after they finished with it.Over 100kms travelled ave fuel 78 l/100ks

ICC needs recalibrating, do it for free whilst trying to slug me $6k for a clutch replacement.

Get farked IMBOs . BTW there is no such animal as a specialist in Fraud service.

Trust me I have used enough of them in 3 states to know NFI

[jetute]

ford know fark all... My zf is flaring (only when cold and has only just now started doing it)... and still has the original oil in it!!

others that have had this issue, have had better results with tranzmax.... which is what I will be trying next.

warren, most people that have high powered cars are running tranzmax fluids in the box, with better results.

and as most of us on this site modify our cars, most of us have no warranty as it is anyway.

Its not the fact that your using Transmax oil in your trans. We have been using ZF oil in these trans's since they where released. My Turbo territory was the first trans I fitted Transmax Z. it developed Issues at 4000 kms on the new car, The trans wasnt behaving itself once the power was lifted. Before I pulled it down a friend of mine did the research and discovered that transmax Z was the oil to use. So we tested it, Trans behaved perfectly and on the same oil STILL is after 60000 kms. I use it in my FG XR8 with 530 rwkw's. It is the ONLY oil I would be using in a ZF trans. We used this oil in big power turbo cars ZF's and has NO issues.

We have been using this oil for over 3 years. So I guess what im getting at is dont blame the oil for what issues you have unless it hasnt been filled to the correct position. Has the vehicle been tuned at all?? The same friend of mine who researched the oil also helps us to do our built ZF gearboxes and we still use the factory clutches in them. Hes been involved with rebuilding ZF boxes for many many years. We replace the factory plastic pan with a steel unit so the filter can be replaced when needed without having to throw out the entire pan at service time. The cars we service making average power we recommend that they change the oil every 15 to 20000 kms. Big powered cars would be more frequent.

I agree completly. Changing to transmax z was one of the best ideas we've had. As for a sealed unit after only 29000 it was shocking. I dont have any problem with flaring or slipping & we've done a few passes down the 1/4 & about 3000klm since the change over.

I'm gonna do it again before we go back down the track just to check the state of it after the treatment its coped. I think it does need to be done regularly after the change to tansmax but that's a small price for abit of peace of mind. Its performing well after 33000klm & well over 400rwkw.

There is definatly no experts in fraud when it comes to these boxes. I went & saw them when I was first looking at getting it done & they said they couldnt help me because they had never done one. A couple of weeks later I saw them again after I got it done by my tuner & they said I was mad & my box was gonna perk its self & they wouldnt cover any warranty because I had used oil that they didnt recommend. All because between when id seen them they did a day or 2 coarse & suddenly knew all about them.

Bloody experts my rear tailpipes!!!

One thing I believe you have to do is fill the box at certain temperatures. I spoke to the guys about it and they said you have to start off with a cold box, fill a littel, then warm it up to a certain point, fill some more, then warm up, then fill, etc etc

This may have something to do with the issues people have had...

[F6_Tornado]

You’re on the money Senna…. These ZF’s only have a very shallow Pan and the oil level is quite low so it doesn’t take much for them to be incorrectly filled and suck a bit of Air when cold.

REMEMBER it must also be checked running and don’t turn off the engine until the filler plug is back in or you will lose a heap of oil.

Sealed for life is OK for STD application as is factory ZF oil but most people HERE run double the Factory torque rating so they require Better oil and servicing more frequently.

I’m sure there is probably a better oil again than TransmaxZ but its been bloody good to me and many others when the trans was US and playing up on factory oil.

I speak to the Tech Reps at ZF regularly and they are fully aware that I run Castrol oil and fully aware how much Torque we put through them and are amazed how good they take it.. They are proud of the box when I tell them what we have done.

These Course are run by ZF and they go through the process as they would for any STD transmission….THEY DON’T cater for modified or increased Torque applications so take what you will from their course.

No Different to Caterpillar saying you should only use CAT Filters and Oil.

So many companies use this threat that you will Void warranty “IF” you use alternative Filter and Oil.

However if the Said oil meets or Exceeds the factory recommendations then the don’t have a leg to stand on and must give you warranty (as long as engine is STD).. If you use some dodgy cheap oil that doesn’t meet or exceed their specifications then you’re dumb to begin with.
