Auto Repair Shop | Milex Complete Auto Care – Mr. Transmission in Marietta


Milex Complete Auto Care – Mr. Transmission in Marietta offers its customers a free Performance Check to help diagnose any problems with your vehicle’s transmission. Our comprehensive performance check consists of a fluid check, road test, an examination and lift inspection/diagnosis. This provides a complete diagnosis of your car’s transmission performance and general operation.

When the results of your performance check show that there is an internal problem with your transmission, we recommend further investigation with an internal inspection of your transmission. This inspection consists of the removal of your transmission and disassembly of the unit in order to view all internal parts. During this inspection, all parts will be examined for wear and damage. When the inspection is completed, one of our technicians will provide you with a report of those items that are in need of either repair or replacement, along with an estimate for those services.


Today’s vehicles are primarily computer-controlled and utilize sophisticated technology to operate properly. The use of this technology plays a significant part in the diagnosis of your vehicle’s performance. When your vehicle is illuminating the dreaded “Check Engine” light or not running properly, computer diagnostics are often needed to determine what part is malfunctioning. In the event that you run into car trouble, we can help. Something as simple as our computer diagnostics testing can usually indicate any internal issues.

Milex Complete Auto Care – Mr. Transmission in Marietta offers computer diagnostics service to provide you with an accurate assessment of your vehicle’s condition. This service utilizes state-of-the-art equipment, which is connected to your vehicle to view any computer trouble codes. Our trained technicians utilize the same procedures the dealerships perform by retrieving this information directly from the vehicle’s data stream to accurately pinpoint your system’s failure or service needs. Once the data is retrieved from the trouble code, our technicians can provide a service or repair recommendation to return your vehicle to its road-ready condition.


Your car’s transmission system is the most complicated system in your car, made up of hundreds of complex components that enable your vehicle to move. It includes transmission fluid, electrical components, universal joints, and a torque converter. For proper transmission repair to take place, these components must be dismantled, cleaned and inspected for wear. This process provides you with an accurate assessment of your vehicle’s problem before the transmission repair commences.

When you make use of our transmission repair services, all worn and/or damaged parts are either repaired or replaced by our experts. After the parts are thoroughly inspected, repaired or replaced, they are reassembled, adjusted, and tested for proper operation, ensuring that your transmission repair leaves your car road ready.
