How Do I Know My Porsche Is Low On Transmission Fluid?

Many car owners think of fuel as the most important liquid in a car. This is of course, not the case. Take the transmission fluid for instance. It lubricates many components and surfaces in the transmission system. In fact, it is safe to conclude that without the transmission fluid, you cannot engage different gears.  That’s not the most interesting thing about the transmission fluid though. The fluid is supposed to remain in your vehicle for its whole lifespan without changing it. Read on to learn more about the fluid and when to change it.


You’ll notice that nearly all signs of low transmission fluid boil down to a transmission fluid leak. To clear doubts, check first the transmission fluid level. Then while at it, inspect the condition of the fluid. If it appears red and it is almost transparent, then it is good. If on the other hand the color is brown or darker, you have a problem. You may have to refer to the Porsche transmission fluid color chart to be sure where the problem lies.

Spots Of Transmission Fluid Under The Car

It may look like an obvious sign but it is not. Many car owners ignore it until the problem is out of hand. Your Porsche has a transmission fluid leak problem anytime you notice small puddles or spots of red or brown fluid underneath it.  In most cases, this happens because of a failed gasket or seal. It can also happen because of a loose drain plug or because of a damaged transmission pan. Whichever the case, take your Porsche for inspection the moment you notice spots of transmission fluid on the surface where you parked.

Slow Gear Engagement

Low transmission fluid means you’ll have a temporary delay after moving the gear lever into drive or reverse. The gear shift won’t take place immediately if there is no enough transmission fluid pressure. The same problem will manifest if the transmission valve body has a problem. This means the car may take as much as 3 seconds to build enough pressure to allow gear change.


A flawless operating transmission should be silent. Rattling noise or any form of noise with erratic pounding while still in gear, park or neutral means the torque converter has a problem. This happens because the car is running low on transmission fluid. Note that this problem can easily worsen especially when you hear clattering or grinding noise while changing gears. This is simply a sign that there isn’t adequate transmission fluid in the system.

Transmission Gear Slippage

This is also a serious red flag. Low transmission fluid can reduce hydraulic pressure in the system which means you won’t be able to remain in the gear you select. This is easy to notice because gear slipping manifests itself by the engine suddenly jumping to a higher RPM mode while driving. As this happens, the car won’t move faster. It may not look like something you need to worry about immediately but it definitely deserves your attention because it compromises safety.
