Veins and Venules: Veins are the large return vessels of the body and act as the blood return counterparts of arteries. Because the arteries, arterioles, and capillaries absorb most of the force of the heartâs contractions, veins and venules are subjected to very low blood pressures.
Wondering when to change your automatic transmission fluid (ATF)? Most manufacturers recommend replacing transmission fluid every 30,000 to 60,000 miles. If you tow, or do mostly city driving with constant changes of gears, it may be wise to change your ATF even more often. Here's why. Your automatic transmission has a lot of moving parts.
You're supposed to change the brake fluid every 2 years or 24K miles. Local dealer charged $78.00 for the job. The transmission fluid change was don't at 39K and cost me $220.00. The original spec called for no fluid changes, but the SA tells me that MB started recommending ONE transmission fluid change at 39K.
