Many non-Japanese conflate sashimi and sushi; the two dishes are actually distinct and separate. Sushi refers to any dish made with vinegared rice, and while raw fish is one traditional sushi ingredient, many sushi dishes contain seafood that has been cooked, while others have no seafood at all.
It's the moisture and contaminents that break down the DOT 3 and 4 fluids which is the reason to change the fluid in the first place. If you don't change it, what happens is moisture enters the system via the vented fill caps on the brake master cylinder. This moisture along with dust, mixes and travels in the system eventually making it's way to the lowest points in the system.
If itâs low, check for puddles around where the car is parked for extended periods of time to see if you have a leak. If no leak is suspected, refill the transmission fluid and test it out. This solves a lot of transmission problems but if you still canât shift then you may need to look at your throttle cables. A faulty throttle cable that has too much slack can prevent proper shifting, or shifting at all for that matter.
