With clear pointers and pro tips sprinkled in, we’ve got your back. So, hop in, and let’s ensure your ride keeps purring with that signature Porsche elegance. Because, let’s face it, a smooth Cayenne is a happy Cayenne, right?

What Transmission Does Cayenne Use?

The Porsche Cayenne 958 came with a 6-speed manual and an 8-speed Tiptronic. Alright, let’s hit reverse for a sec, shall we? Rewind to 2010, when the second-gen Porsche Cayenne made its grand entry. The base model came standard with a nifty 6-speed manual transmission. Craved an 8-speed Tiptronic? That was your swanky add-on!

But, twist in the tale: the rest of the lineup? Outfitted with the 8-speed Tiptronic from the get-go. And, surprise, surprise, no manual for them. Reality check: a limited bunch of Cayennes with that 6-speed manual ever rolled off the assembly line, and an even slimmer number hit the American tarmac. If you’re behind the wheel of one? Kudos — you’ve got yourself a real gem!

By the time the Porsche Cayenne 958.II debuts in 2014, Porsche was all about that 8-speed Tiptronic life. Not a snub to the manual transmission, though. That beast held its ground majestically.

The switch-up? Largely thanks to the dwindling demand for manuals. Times were changing, and automatics reigned supreme. The Tiptronic brought those seamless shifts and driving ease everyone was vibing with. Even though the old-timers might have a soft spot for the manual, the message was loud and clear: the Tiptronic was the crowd-favorite.

Was the Tiptronic transmission the right choice for the Porsche Cayenne?

Porsche’s arsenal? Three key players: the nostalgic manual, the dependable Tiptronic, and the futuristic Porsche-Doppelkupplungsgetriebe (PDK) — yup, quite the tongue-twister. But in layman’s terms, it’s Porsche’s answer to the dual-clutch transmission. And man, the PDK is the stuff of legends, tailored for light-speed gear swaps. We’re talking killer fuel savings and an ultra-responsive drive, keeping you locked into that sweet power range.

But, plot twist — why’s the Cayenne side-eyeing the PDK? Isn’t it the crowned prince? While the PDK is all about that racetrack hustle, it’s not packing the muscle for hefty towing or rugged trail-blazing. Asking the PDK to toe the line for the Cayenne is like expecting a marathoner to morph into a powerlifter! Conceived with the race circuit in mind back in the ’80s, the PDK’s just not wired for Cayenne’s adrenaline-packed escapades.

That’s why the Porsche maestros in Weissach gave the Cayenne the Tiptronic badge of honor. Packing the punch for heavy-duty towing and the finesse for untamed terrains, the Tiptronic is every inch the contender. Don’t get it twisted — it’s nimble, fierce, and every bit the match for the Cayenne’s wild side!

Performing ATF Change on the Porsche Cayenne 958

Alright, enough geeking out over Porsche Cayenne’s transmission legends. Ready for the main event? Swapping out that ATF and filter isn’t the beast you might think it is. Seriously, it’s pretty much like any other car, just with a couple of Porsche-flavored twists.

But let’s get one thing straight: SAFETY FIRST! Rock that PPE like it’s the latest fashion trend. Got an oil spill kit or something similar? Awesome, keep it close. And let’s not forget those trusty tools. Using the right ones not only keeps you and your ride safe but also shaves off time and hassle. Alright, gear up! Here’s what you’ll need for our ATF makeover party.

• Working gloves
• Safety goggles
• Oil spill kit or rags and sand
• Lint-free rags
• Hydraulic jack rated at 2-ton
• Jack stand rated at 2-ton
• Mechanic’s creeper
• OBD diagnostics tool
• ⅜” drive ratchet and socket set
• Hex bit socket set
• Hex Allen key set
• Oil drain pan 2.5 gallons
• ATF filling tool (VAS 6262)
• Adapter (VAS 6262/2)

Lifting your ride

If your car has an air suspension system, you should set it to maximum height and see if you think you can work on this height. If not, you might want to set it up at your comfortable working height with a jack stand; just make sure the car is leveled and neither the front nor rear section of the car is inclined. This portion of our repair is already covered in our article about lower control arms. You should definitely visit it to learn more about your car.

Removing underbody panels and bracket

Now that the car is up at the height you are comfortable working with. It’s time to jump in and get your hands a little dirty with some splash pan action. First on the agenda? Sending that under-engine protective splash pan packing. Remember, it’s a dynamic duo — two parts working as one.

Let’s make sure you’re geared up. Whip out that reliable 10mm socket for the splash pan bolts. Quick heads up: keep a bolt loosely hanging in the rear. This trick lets you support the pan while you unscrew the rest, avoiding any unplanned splash pan showers.

Here’s the game plan: bid adieu to the rear splash pan first, then give the front the same treatment. For the front pan, a slight tilt downwards and a nifty slide away from the car do the trick.

Oh, and before you dust off and call it a day, there’s the little matter of the splash pan mounting bracket. Grab that 10mm socket of yours, and tackle those three fixtures (two nuts and a bolt). And since it’s a two-piece part, too, it’s gonna be a walk in the park. Keep going, champ!

Draining ATF

Alright, let’s get down to draining the ATF from your Porsche Cayenne 958. Start by locating that transmission pan fill/drain plug. Got it? Great! Grab your 5mm hex Allen bit and gently loosen the plug, allowing the old ATF to flow into your waste oil drain pan.

Once you’ve got enough of the ATF out, take a closer look inside. You’ll see a plastic fill port level insert nestled in there. This little guy also needs that 5mm hex Allen bit. Remove it, and you’ll release the remaining ATF. Oh, and make sure to clean any spilled ATF on the floor with an oil spill kit or with rags and sand. We don’t want you to trip and hurt yourself. Remember our rule: Safety first!

After all that draining action, it’s time to put things back together. Slide the fill port level insert back in, hand tight, and do the same for the drain plug and its sealing washer. This ensures everything’s tidy and prevents any spills when you’re onto the next steps of cleaning or removing the pan. 

Removing ATF filter

Next up on our DIY journey? The transmission pan. First things first, it’s held tight by those 10mm bolts. But heads up, those bolts on the front side of the pan? They might play a bit hard to get. A swivel head extension or socket could be your BFF here to make things smoother.

Kick-off by loosening up all those transmission pan bolts. All loosened? Great! Now, remove every single bolt but leave two — ideally at opposite ends. They’re your safety net. Hold the pan up with one hand and remove those last two bolts. Watch out because there’s probably a little sneaky ATF still in the pan, waiting to make a quick escape. Get that transmission pan lowered and let any leftover ATF flow into your waste oil drain pan. 

Alright, let’s get that old Porsche Cayenne transmission filter out of there! It’s held in place by four 10mm bolts. Oh, and don’t forget to ensure that the old O-ring — the one sealing the filter to the valve body, comes out with the filter. 

Replacing ATF filter

Now, for the fun part — pop in your shiny new transmission filter. Make sure that the fresh O-ring is snugly in place on it. Pro tip: dab a bit of Porsche Cayenne ATF on that new O-ring. It’ll help it settle in just right against the valve body. Push the filter on its mounting hole to ensure it is seated correctly. And when you’re securing everything back with those four 10mm bolts, aim for a torque of 7 ft-lbs.

Next step: throw away that old rubber gasket on the pan. Then it’s time for a thorough cleanup: wash out the pan and those little magnets inside it from all the gunky ATF and residue. And hey, remember where those magnets were placed? Make sure to pop them back in the same spots once they’re shiny again. Brake cleaner and lint-free rags will do wonders here.

Now, focus on the gasket mating surfaces on the transmission and the oil pan. Get rid of any old gasket bits and any junk. And a quick heads-up: steer clear of the transmission internals and always use lint-free rags.

Moving on! On a clean workspace, fit those gasket spacers into your new gasket. Place the gasket onto the transmission pan, ensuring the mounting holes line up. Now, reunite the pan and its gasket with the transmission. Spot those mounting holes and get those eleven 10mm bolts in there. Start by hand-tightening them uniformly. Then, go side-to-side on the pan, torquing those bolts to 7 ft. Lbs. Voila! You’re all set!

How much transmission fluid does a Porsche Cayenne hold?

For the Porsche Cayenne 958, the transmission fluid capacity largely depends on the specific maintenance scenario. Starting with a completely dry system, which includes the ATF cooler, ATF lines, and torque converter, you’re looking at a fill capacity of 10.5 to 12.7 liters. If you’re going through a drain and filter change, you’ll typically require between 7.4 and 9.0 liters, considering that this can vary based on fluid temperature and the inclination level.

Filling ATF

Alright, gear up for the next phase — filling ATF in your Porsche Cayenne’s transmission. Grab that fill adapter (VAS 6262/2) and hand-screw it onto the fill/drain plug port of your transmission pan. Got it in place? Cool. Now, slide that fill hose onto the adapter. Quick check — make sure your vehicle is parked level. We don’t want any wonky angles here.

Time to get pouring! Using the trusty VAS 6262, fill the recommended ATF into your transmission. Aim to pump in around 6-7 liters to begin with. Once you’re done, fire up the engine and let it purr. Now, foot on the brake, smoothly cycle through all the gears (P-R-N-D) while keeping the engine idling. Give each gear a 5-second rest and repeat this little dance three times. This groove helps any sneaky air bubbles make their grand exit from the transmission.

Still with me? Great! With your car in park and the engine idling, top off the transmission with the remaining 2 liters of ATF. Once you’re done, yank out the fill adapter and snugly fit the drain plug in place to prevent any sneaky drips.

How do you check the transmission fluid on a Porsche Cayenne?

To check the transmission fluid on a Porsche Cayenne, start with your engine idling. Aim to get the transmission fluid’s temperature between 95°F to 113°F (35°C – 45°C). Your go-to tool for this is the OBD, but a quick tip: ensure it can read these specific temperatures. As you’re monitoring, it’s a race against the clock because that temperature will keep rising.

Once you hit 95°F (35°C), it’s action time! Remove the transmission drain plug. If things are going right, you’ll see the ATF spill out from the fill port level insert into your waste oil pan. If you’re seeing a constant flow that gradually slows to a mere dribble, all within the 95°F to 113°F (35°C – 45°C) range, you’ve nailed it!

Didn’t see any ATF flowing out? No worries, just add more fluid until you see a trickle, but make sure it’s within the temperature window of 95°F to 113°F (35°C – 45°C). Once you’ve achieved this, pat yourself on the back and replace that new fill plug with a gasket, too.

Very important note: Never let the ATF temperature cross 113°F (45°C) during this process. If it goes above, secure the drain plug and sealing washer, turn off the engine, let it cool down below 95°F (35°C), and run the fluid check again. Stay patient, and you’ll ace it!
