These guys rock! I took my 05 Mercedes in to the local Mercedes dealer. The dealer told me I needed to replace my transmission. After Westside transmission diagnosed the problem, they called me stating that I needed a sensor replaced. At first, I said how is it possible that the dealer said it needed a transmission and Westside transmission says my transmission did not need to be replaced? Well, Jack at Westside transmission was very knowledgeable and explained the problem in language I could understand. To make a long story short, Jack / Westside Transmission was right. The problem ended up being a bad sensor. I already and would highly recommend Westside Transmission to everybody I know. Like I said ... these guys ROCK! Not to mention the money I've saved by dealing with them.
