Q: Loud sound from under hood

asked by on February 04, 2016

I have a very loud sound coming from under the hood, almost like a belt or something is loose. I just had a tune-up, but the Check Engine light is coming on. When shifting gears, the indicator doesn't match what the car is actually doing. I recently got the transmission replaced and a tune-up. The Check Engine light still comes on and now the truck is making an extremely loud noise under the hood.
