I took my first trip out of town in 2001 that I bought 17 days ago. Has 139,000 miles, when returning home to MD from N.C. vehicle started to lose speed cruise control. I took it off and was giving the car gas manually it stopped shifting into the higher gear. We were down to 20 mph on the side of the highway limping along until we found civilization. A very nice mechanic looked at it for me and scanned it, he said it was the solenoid/ torque converter code. He tried a couple people that sold him parts and they didn't have the solenoid. He tried cleaning out the one on my vehicle but he said it wasn't really dirty, but after he cleaned it the problem wasn't fixed. He said there wasn't anything else he could do at that time. We tried to make it home but it wouldn't go above 20 mph, ended up parking it and calling family to come rescue us. Now the car is 5 1/2 hours away broke down. Any advise would be great!!!!!
