Hello everyone. I am new to the forum so bear with me please. I have a 2005 Uplander ls with less than 50000 miles that moves in 1st and 2nd gear but will not go beyond that to full driving gear. Wondering what could be the problem. I have researched many things such as the pressure control solenoid to a simple transmission cable adjustment. Any ideas would be of great help, would like to get her back on the road in use. Thank You.
