So for everyone that has been discussing Porsche Cayenne ATF....AKA JW3309/LT41171.Porsche PN 000 043 205 28There has always been debate on Toyota Type IV being the same as the Cayenne ATF. So i sent in VIRGIN SAMPLES to blackstone to get the analysis on additives.The results are shown below:..........................................Cayenne ATF....................Toyota Type IVBoron.......................................73.........................................84Calcium...................................128.......................................105Phosphorous...........................292.......................................271Zinc...........................................6..........................................11SUS Viscosity @ 210F.............48.3......................................50.1cSt Viscosity @ 100C..............6.74......................................7.26FlashPoint in F........................410.......................................370Translation.....Both fluids are chemically the same as far as blackstone can see with their equipment. I attached the Porsche ATF slip for reference. VOAs cost $$, but well worth it if it saves cash down the road. I have some diff fluids coming as well for a VOA as well. The flash point requirement is >335F, which both exceed.So save yourself some $$ and buy the ATF from Toyota.

Looks interesting - but what were the viscosity numbers and do they do an ash-point on ATF?

It also would be interesting if Blackstone has done Mobil-1 ATF since that apparently meets the ESSO LT41171 standard.

Hello to all. I'm working on my 04 Cayenne S. Just changed the front and rear diff's fluid with LUCAS 75 W90. For the Transfer Case I was considering 3 oils.. Bilstein 14738 which has a Flash Point of 190C and ZF 5 which does it at 220. To me and thanks to the great info. from Clarksongli it looks like the Toyota Type 4 is the winner with a Flash Point of 370C unless I'm measuring wrong. Called the Dealer in Tampa where I live and they want $75 bucks for a quart and yes $6 bucks at the Toyota dealer.

Like i messaged you about....i run it in both my transfer case and my auto tranny.....no issues.

Took a Porsche Master Mechanic (friend of mine) and about 100 bucks to get the samples tested and compared at blackstone.....but well worth it as you can see......75 bucks for fluid.....that's a profit margin i'd like to have.

I used to have an '84 928 I owned for 17 years and recently sold which has a Mercedes Benz tranny. I'll never forget many moons ago getting a price at the Porsche dealer for $70 bucks for the filter and gasket and going to the Mercedes dealer and buying it for $14. That's another example of Porsche marking up stuff.

yeah M1 does have a higher flash, only difference though is the OEM fluid was not a full synthetic if i remember correctly. I know plenty of people that run Redline and other full synthetics, i just was a nervous nelly so i stuck with the OEM fluid.

Again i know plenty of people running synthetic now, i just chose to stick with OEM.....similarly with the diff fluids....the locking diffs use a friction modifier, so going to a full synthetic could potentially alter the friction plates in the lockers.

Unfortunately i could NOT find a direct replacement for the OEM diff fluids.....If i didn't have or use the lockers often, i would probably have just used the Redline alternate.

So how long any of you on the Toyota ATF, have had the car on so far in miles and in months (after changing from Porsche fluid)?

Any comments after your interval (smoother, not smoother, cannot tell diff, etc)?

Just wondering.

anyone?

anyone?

Of those who switched to Toyota T-IV ATF for tranny fluid replacement, how many miles have you driven since, and have you experienced any issues or warnings (anything of note)?Would be greatly beneficial to others who have been monitoring this. Thanks.

Not the Toyota fluid but I've been on Redline D4 for over a year. Seemed to shift a little better in the cold than it did on the OEM fluid, feels the same when warm.

I've been on Mobil 1 synthetic ATF for 2.5 years now. It used to be approved now it's not. I'm not recommending it specifically, rather saying don't lose sleep over using an unapproved fluid.

I caveat that statement with this: unapproved fluids still must be of the 'correct' type. Aka, don't use the wrong fluid.

Sorry Ciaka, i'm on and off these forums.

I'd think i have roughly 30k on the fluid i think? Still running strong as ever....i just pulled several 30" inch stumps, and delivered a mini excavator for a friend. I certainly put my CTT through it's paces, which is why i bought it in the first place.

Shifting is not any different, cold and warm shifting seem to be the same. my plan is to flush it one more time since draining/filling doesn't remove all the fluid at once.

      Does anyone have a wiring diagram for the seat on a 2008/957 Cayenne which they can let me have?

      I’m trying to chase a fault where the passenger seat will motor up and down and the backrest will adjust forward and aft, but there is no response from the controls to move the seat unit forwards and backwards, or the four-way lumber support control.
       
      Thanks in anticipation...

      My front wheel was making a rattling noise for about the last week, and this morning as I drove out of my driveway and turned the wheel, I could hear a loud popping noise coming from my wheel whenever I turned. My best guess is that I drove over a pothole and the control arm / bushing moved out of place. Would this be covered under the OE warranty? Or should I take it to a mechanic?

      Hi there, my Cayenne is telling me my driver's side door is open when it is not. This is causing the dome light to stay on. Not sure what the issue is and if can be fixed easily. Any info given is greatly appreciated, thanks!

      Hello everyone,
                Does anyone have or know where I may have the bolt torque specs for a 2008 Cayenne Turbo? I need pretty much the specifications for all the bolts and nuts that would be included in a block replacement. I'm getting the back rebuilt by 928 Motorsports and reinstalling with an experienced friend. However, it's nearly impossible to find the specs for these motors. Additionally, if there's a place where I could find a complete 957 workshop manual, could someone please advise? Thank you.
