Not sure if this is the correct forum but I have a new to me 97 Suburban with 220,000 miles on it.The transmission was replaced about 4 years ago. At highway speeds it has a rumble. really starting at about 60 mph. When going downhill if you let off the gas it goes away but comes back immediately when power is applied. It is hard to tell when driving where it is coming from, but seems like more from tranny area. I checked the tranny mount and anything obvious bit I don't see anything. Any help or ideas would be great.
thanks
