My trans was slipping this morning. I stopped at Autozone for some fluid and noticed trans fluid leaking out toward the front of the car. One of the cooler hoses was dribbling. Luckily I found the parts in town but spent the rest of the morning fixing it in the cold parking lot. Not so easy to get to them. And the old ones didn't want to come loose.
Something worth checking next time you are under the car!
