Transmission jolt problem ? Gear 1-2 "Is like i get hit from the rear! 03 X5 4.6 is"

[bosanci28]

yes, it could be anything wrong at this point, i have to change few basics ,before going deeper into the tranny.

and , i am the same too , i let the rpm go down and then easy go,and it does not doing the jolt ,but if you force it it does.


anyway,will post here updates whenever i get into the x5 to do some work on it.

Any news?

[bosanci28]

Not yet,no news.

I am waiting for the INPA cable and software to arrive from Europe,
so i can check what @fmugur was saying!,then will go from there on my next step.

Thanks,

i was today at the autozone looking for something and i have discovered on a valvoline max life atf bottle this number also:

LT71141 witch is for ZF Transmissions also based on the ZF chart?

autozone link here ,







well is recommended by valvoline to use...

Some people used Valvoline. Not sure how good it is, or how it will last, or if it will affect the transmission negative.

One point I have to make: they list all those BMW approved ATF's, which are all different p/n (11 digits per BMW) and have different applications (different transmissions), yet this magic Valvoline MaxLife can be used for any of these?

Attached is the BMW ATF approved list of oils. Call it the BMW ATF bible if you will.

It is unfortunate that this is the way the world works, but you actually have to read those labels like a lawyer, to see the subtle differences in the labels they put on each bottle. That label is designed to fool unsuspecting consumers.

"Recommended for use in...." is a phrase that oil and atf companies use when they don't meet the specification. They are saying, essentially, that they don't meet the specification but you should trust them and use it anyway, it will be fine. It very well may be. But it doesn't meet the specification. And as was pointed out above, ZF themselves caution not to use Dexron due to issues with clutch engagement, yet this fluid is somehow a Dexron fluid and a ZF fluid at the same time. The fact that they say it is good for different specifications, when those specifications themselves are contradictory, is a sign that they are playing games. They are saying that they know more about the ZF transmission than ZF does. I think that is nonsense.

Valvoline say on this bottle that it is recommended for use where Dexron is called for. But at the same time, they sell a different ATF that does meet the Dexron spec. The language they use on that label is "...meeting and exceeding the requirements of the General Motors' DEXRON®-VI specification." That is very precise language. (As an aside, you will note that they use the trademark symbol. That is another tell tale.) And the bottle you showed the picture of is not the same fluid, but they think you should use it anyway. If you needed Dexron fluid, which would you use? They can obviously blend a fluid to a spec if they want to. They are already paying the license fee. And they are selling a generic fluid at the same time. The trouble is, with the ZF fluid spec, they don't have one that meets the spec, they just sell the generic fluid.

The multi purpose fluids are not designed for your transmission. They are designed for automotive shops who don't want to stock different fluids, and want one generic fluid so as to keep their inventory costs down. It is a bad reason to select a particular fluid.
