on my way to work this morning my transmission started to make whirring noises when ever i accelerated.(well, it came from the floor where the front of the transmission is) when i let off the gas the noise went away for the most part. When i would idle how ever, it sounded kinda like a diesel truck. I think its my torque converter, but im not sure. any help would be awesome. I checked the fluid and its good. just as i pulled into the lot here at work, my check engine light came on. thanks for the help.
