I recently had to change the filter on my 2004 GMC Envoy, less than 2,000 miles ago. Two days ago, the transmission started acting funny. It wouldn't stay locked up in OD. I noticed the RPM's would fall to around 1550-1600 when running 55 mph (normally run 1800), and I would feel the vehicle shutter, and it would just kick out of OD. Anyone have this happen to them? vehicle has 213,000 miles.
