I recently purchased a 2008 Expedition. It has 70,000 miles on it. I had a 200+ mile drive home from where I purchased it. When I test drove it, no issues.
About 30 miles into the drive home, as I was exiting the freeway from speeds of 70MPH, when I decelerated on the off ramp there was a sudden LOUD clunk, accompanied by a sudden jerk (felt like I had just been hit from behind). The truck seemed to lose power momentarily. I thought I was going to have to coast off the exit ramp, but it regained power and then drove without issue for some time.
About 100 miles later, while on the freeway with the cruise control set at around 70MPH, it did it again. LOUD clunk and heavy jerk, like I had been hit from behind again. This time no power loss, but still very startling.
I made it the rest of the way home (another 80-90 miles without further incident). The truck shifts smoothly through all gears, doesn't have any odd noise or vibrations, no hesitancy or stuttering. In other words, everything else seems great. Just these two incidents (so far) that seem like they may be the sign a transmission issues?
Any ideas? Anybody else had this experience? I read some other forum posts that describe these symptoms, but those post mostly describe this occurring at low RPMs. Torque converter?
