A few months ago I had my transmission serviced at a Fast Lube Joint. In the past week the tranny slipped a couple of times while idling in traffic. I felt the difference and was careful not to over rev as it kicked back in gear. I checked the fluid level and found it to be extremely over filled. I immediately took it back in to them and had them evac some of the fluid until it was at the proper level.
As this car has close to 300,000 km on the drive train I am very concerned over the possible damage this might have caused?
Can anyone enlighten me?
