Pentosin Transmission oil

[spamking98]

Does anyone know if this is the right oil for my 2002 bmw x5 4.6is ? and I have a spx filtran filter? anyone have any problems with these items after using them on their X? To tell you the truth im a little scared to change the transmission oil and filter...Im still waiting till the rain stops then im going to build the ramp and hopefully get this job done with.. I dont know if it will stop the slipping in the transmission, I have about 87k miles and the fluid has never been changed before and I am the 2nd owner of this vehicle.. I may have to return it to the creditor if this doesnt fix it... I have no more money to fix this beast. I really enjoy driving it but the cost of owner ship is driving me into the poor house...pun intended...

Use Mobil Multi Vehicle ATF by Exxon it's what BMW recommends "LT 71141"

[JCL]

Pentosin advertises that their ATF is suitable for BMWs (with green transmission pan labels) but doesn't differentiate between the GM and ZF transmissions, which use different fluids.

They also don't list compliance with the Esso LT 71141 spec that BMW calls for.

It will probably work, but why take a chance on a fluid that doesn't meet the spec?

@diyanich, so have you used this mobil multi atf on your x before? I checked the mobil website and did not see anything stating that the atf was compatible with lt71141 esso.

@jcl, your right, pentosin doesnt state whether its for gm or zf...when i ordered it through carquest i gave them my transmission model which is 5hp24 zf and they told me to use the pentosin atf and filtran filter.

I appreciate both of you guys feedback on this....thanks

I am researching before the actual flush,my tranny was rebuilt by the local shop and they poured dextron VI into it,so I am getting shudders in the moment of Torque Converter lock up.I was able to find the fluid locally at Canadian Tire for $ 29.99 /5 liters container.
I read the label and it's got : BMW 7045E LA2634 LT 71141 .

Here is the link:

Mobil Multi-Vehicle Automatic Transmission Fluid, 5L | Canadian Tire

Here's another thing I researched from Automatic Choice

Esso LT 71141 Transmission Fluid

Esso LT 71141 also know as LifeGuardFluid5 is a semi synthetic transmission fluid specially formulated for use in ZF five speed transmission units, although it is also required for the ZF4HP20 transmission. All ZF units requiring Esso LT 71141 can be identified by the colour of the ID tag, which is green. Please note that this fluid is not suitable for ZF six speed units which require LifeGuardFluid6 or LifeGuardFluid6 Plus.

It is becoming increasingly important to use the correct grade of oil in late model transmissions as failure to do so can result in numerous shift and torque converter related problems with eventual failure of the unit.

ZF’s response to using alternative fluids is quite clear, they say the design specification of these units require the use of Esso LT 71141. There is no alternative or equivalent oil, Esso is the only supplier of LT 71141. The transmissions are not designed to run on any other fluid and if installed you run the risk of premature failure. The transmissions are equipped with sophisticated torque converter lockup control (TCC) systems and the correct oil specification is critical to their function and operation. One of the main functions of the oil is to provide the correct coefficient of friction and cooling of the torque converter lockup lining during regulated slip conditions. The longevity of the lockup lining could be adversely affected by the use of the incorrect grade of fluid and in most cases deterioration in shift quality and lockup engagement is also experienced.

With this in mind it would seem unwise to supplement this oil with any other, as you could lay yourselves open to warranty claims upon any subsequent failure of the transmission.

Esso LT 71141 is an extremely well specified fluid and many of our customers have used it with success in other transmissions requiring high quality semi synthetic fluids such as DP0 and JF506E, a case in point is the Jaguar X-Type fitted with the JF506E transmission, if after rebuild these units are not filled with the recommended fluid, the oil pumps are often very noisy, sometimes to the extent that imminent failure is expected. On a couple of occasions customers have told us that they have drained as much fluid from the transmission and converter as possible, refilled it with Esso LT71141 and hey presto all is quiet.

Although we would always advise using the oil grade recommended by the manufacturer, it does seem that if you are unable for any reason to use the correct grade, you may find that Esso Lt 71141 will fill your needs for a premium quality ATF.

Esso LT 71141 (20 Litre Canister) Our Part No. OIL.51
Esso LT 71141 (208 Litre Drum) Our Part No. OIL.52

And yet another thing from other forum,the last thread especially:
Esso LT 71141 vs valvoline max life or castrol import atf - Bimmerforums - The Ultimate BMW Forum
But again I personally go with the BMW recommended fluid.
I am having the local tranny shop flushing the Dextron some time after new year holidays,and refill will be Exxon's Mobil ATF.
My shudders and slipping between 1&2 gear started after the fluid change(partial,no Torque Converter) by the shop that didn't care much about the brand and fluid specs.I didn't know of such a difference either since it's the first Auto box for me,may be the last one as well....

Has anyone tried this royal purple yet in their x5s transmission? im curious to try it since it does state that it meets the lt71141 specs...

That site doesn't say that it meets the ZF LT spec. It says that Royal Purple recommend you buy their oil and use it for applications where that spec is required. The spec is an Esso/Exxon spec. ZF say you have to use that oil. That is the only oil that meets it. I am not saying that other oils won't work, but the fundamental nature of a proprietary spec is that it is proprietary.

You have to read manufacturer's claims closely. Not only do Royal Purple not say that it meets that spec, but they say it is good for transmissions that require the LT spec, and also for transmissions that require Dexron. We know from experience with BMW transmissions made by GM and by ZF that they need different fluids. Royal Purple is selling a 'univeral' fluid that they say works for everything. So, it is a miracle fluid that covers all specs, or a utility fluid that doesn't actually meet any of them?

Any BMW automatic that used Esso LT 71141 will operate well with Pentosin ATF1. BMW even sells it as a replacement. That said the latest data I saw from Mobil is now called Mobil/Esso LT 71141 and other Mobil site show the blue 1L Mobil plastic bottle labed Mobil LT 71141 which is the replacement for Esso LT 71141. I have used Esso LT 71141 in my BMWs spec-ing it and will soon change my friends X3 that I have discovered will accept Pentosin ATF1 as a direct replacement.
Since Mobil makes the previously labeled Esso LT 71141 you would think it would be more popular.

I just am not planning to take the risk with anything but Esso or Pentosin until I see the Mobil LT 71141 more available. That formulation is very slippery but also seems to have modifiers that make the transmission function well. If ZF isn't recommending it than I sure am not putting Royal Purple, Redline, Mobil mutivehicle ATF in the M3 or X3.
This is a good data source for those of us that don't buy into the lifetime fill. In fact ZK now states that the so called lifetime fill should be changed every 50K miles thus so much for lifetime...

Just got the tranny flushed with Mobil Super Multi Vehicle ATF which is LT 71141 about 90% of fluid and shifts are extremely soft so far.
I don't see any reason to experiment with other than OE recommended fluid.
5hp24 = LifeGuardFluid5= good result as engineered.
Here's the quote from ZF technician I have contacted :
" What oil is being used before and after the rebuild? Oil type is critical on these transmissions and using any aftermarket oils other than ZF Lifeguardfluid 5 or dealer OE fluid may result in drivability problems. "

Also the fluid level is critical,after the first flush I had a terrible shudder at low temps and it was almost gone after it gets to the operative temps.
Last flush(today's) supposed to get the level right,guy said it didn't shudder,will see tomorrow morning.
