Hello I have no idea about cars, but I am in a bit of a bind. I have a 2003 Dodge Grand Caravan and my check engine light came on last week. The local car shop read the code which said "solenoid stuck on low/reverse". I took it to a transmission place he recommended and got a free estimate. They said the Solenoid Valve Switch needs replacing and the total will be $518 out the door. I don't know if that is fair or not, but I do know I don't have that off hand and won't for a few weeks maybe. Is it safe to drive the van with this problem? Will it do any further damage? Any info would be helpful, and thank you I'm advance!
