I've never known much about cars. I knew putting keys in the ignition would start them up. But that's about as far as my knowledge of cars went. Obviously there a lot more to know. My transmission education started last summer. It was a warm day. I was on my usual route to work. As I sped up past the burrito joint, I shifted into third. I felt a quick stall and angry rumble emanating from the engine. That's not a good sound. For the next ten minutes of my commute the same thing would occur. Fantastic, I muttered to to no one. I arrived to work and luckily Tom, an automobile expert was already there. He knew what the problem was right off the bat, as soon as I told him what happened. He informed me all about transmissions, even though I didn't need to hear half of it. He said the problem was most likely old transmission fluid. When the fluid wears out, it becomes less effective at its job, which is to keep the transmission lubed, or something. I might need a transmission flush. To confirm his theory he sent me to a good repair shop down the street. I clocked out and drove over there. The Jeep Cherokee custom seat covers mechanics were nice. They even offered a free diagnostic test. Even before the test came back they already knew what the problem would be. And my co-worker was right. After the mechanics flushed my transmission I was back on the road, my car running smoother than ever.
