I have another wonderful experience dealing with DuPage Transmission of Naperville…read more My daughter left for Iowa City on Friday for a friends graduation weekend. While enroute to Iowa she stopped at the Decalb Oasis for fuel. Uppon leaving the fuel pump the car started bringing and would not shift into park and the car was inoperable. She called in a panic and told us what was hapening. Our daughter doesn't deal with these situations awesomely and threw up. I told here to engage parking brake and turn on the hazards. I would be on my way and will be there in less than 30 mins. As I got there I see she is stopped in the middle of the driveway parking lot and causing a backup at the oasis. I approach the car and ask her to turn off the ignition. "DAD I CAN'T" is her response. I show her how the shift lock over ride is used and get the vehicle into neutral. We push the vehicle into a parking spot and remove her personal items, leave the vehicle unlocked and head back to Naperville. While driving back to Naperville I call Dupage Transmission and speak with Scott. I explain the situation and he gives a suggestion of a flat bed tow company. "Get it towed and we will get it fixed today" Wow a shop willing to stop their other projects to get me back on the road asap! The vehicle waswas back on the road same day and my daughter was able to not cancel her weekend. A true mom & pop establishment that only cares about their customers. This was such a pleasurable experience that I had them complete a few other maintenance items I've been putting off. The vehicle is ready for another 90k. If you want an experience like this with your vehicle repairs I suggest using DuPage Transmission of Naperville. Many thank yous to Scott and his team
