: EXT Transmission Chattering

11-21-10, 10:24 AM
Hi guys,
Between 30-50 mph my '06 EXT (100,000 miles) will vibrate badly as if I'm hitting the breakdown lane ridges. I can stop it by accelerating or tapping the brake. Had my long time mechanic do a tranny service, (solenoid was OK) and he's thinking I better start planning for a replacement. Anyone have any experience with this?
Thanks, Paul
