Hello. I was wondering if anyone experienced this. I have a 1999 EB expedition. When it shifts, I'm getting a vibration from the back end. Almost like hitting a rumble strip for a second. Once it shifts, it's back to running smoothly. I did notice some gear lube in the back rear rotor when I changed the brakes, and can occasionally smell it when I drive it. Thank you for any input!

 

 

Not exactly sure. The vehicle was given to me. Maybe I'll start there!

 

Probably won’t get a response being that this thread is 5 years old but did the transmission fluid change help the vibration? i’m having the same exact issues you are describing

 

At what speed and how long does the vibration last??

When was the tranny fluid last changed?
