There are a few things that can soak up transmission fluid, including:
-A rock or metal object in the transmission fluid
-A clog in the transmission filter
-A hole in the transmission fluid line
Most transmission fluid is blue, but it can also be green or red.
Transmission fluid should be changed every 7,500 miles or every 3 years, whichever comes first.
There is no definitive answer, as transmission fluid may help shift in some cases and not in others. Some drivers swear by changing their transmission fluid regularly, while others say it isn’t necessary. Ultimately, it depends on the individual’s driving style and how their transmission shifts.
WD 40 does not specifically target oil stains, but it is a general cleaner and degreaser. If the concrete is dirty, WD 40 may be able to clean it up. However, if the stain is oily, then an oil-specific cleaner may be necessary.
