There are vital fluids that circulate through your engine. Like other fluids, transmission fluid can decline over time. Transmission fluid gets beaten up, hard use, things take a toll on the engine and the fluid, like daily stop-and-go city driving. Soon the other issues of taking your car out starts to accumulate and eventually you’ll start to feel your engine start to wane. The solution, of course, is to replace the old fluid with new.

When Do You Replace It?
A rule of thumb with many mechanics say it should be done at least every 50,000 miles. However, the manufacturer’s maintenance schedule for many transmissions doesn’t call for fresh fluid until 100,000 miles – you need to check your owner’s manual to see what BMW recommends for your model.

Checking Your Transmission

You might be thinking to yourself, ‘what if I have an older car and I’m unsure how long ago the transmission fluid was changed last?’  Here is a good tip for a quick method to check out its condition. When transmission fluid is brand new it is usually red but when it gets old, it tends to turn darker, nearly black, in color. It also starts to smell burned after a while that is a good sign that it needs to be changed, eventually if the fluids aren’t changed in the transmission will start developing mechanical problems. Another good signal it needs changing is that you can feel gritty dirt or other debris in the fluid when you put a drop between your fingers.
