What Our Customers Say

This was a great alternative to the dealership out at the Milex Auto Repair Center in Warren. They are right around the corner from me and were able to replace the driver door master switch for the window control in one day.
Janice Woods
"If you are interested in doing business with a truly professional service staff, Multistate Trans Milex is the place to have your car serviced. The whole staff provide worry free service at a very affordable cost. They back up each job 100%, explain the work that was performed, and deal with you as a friend and not just another customer. My family and I have had our cars serviced for 50+ years. I will recommended this repair shop to my friends and family. Do yourself a favor and drop them a call for Audrey or Jeff.
Jimmy Gavist

Martin Santini
Great people from the technicians to the owners. They communicate all thru the job in language a layman can understand. From quick service oil changes to the most complex of jobs they are experienced and professional. I highly recommend MILEX of Warren for all automotive needs. Joe
Joseph Carpino
The owner was very informative in explaining what was wrong with my transmission. They did a great job taking care of the issue. Their financing option was great also because it allowed me to pay a portion up front and then finance the remaining payments.
Melissa Dwight
I was traveling through Warren and my car decided to break down on the side of the highway. Great!!!! I took my car to JB DLCO & Multistate Transmissions expecting to have to rent a car for the rest of the trip and then take a second trip back to drop the rental car off and pick up my car. I was so upset but to my surprise they told me it would only take a day for them to pull and install a reman transmission! I didn’t even think that was possible!!!! I couldn't have asked for any better service then I had received at Multistate Transmissions. Jeff and Audrey are the best!!
