I took my Ford F-150 to Premier Drivetrain in Bay City for a complete drivetrain service, and I couldn't be happier with the experience. If you own a truck with the 10R80 transmission and do a lot of towing, having it serviced every 50k miles is a must, and these guys are absolute transmission experts.
They didn't just drain and fill; they performed a thorough check before and after the service to catch any potential issues early. They even cut open the old transmission filter to inspect what it had caught! That level of attention to detail is hard to find. Quality work at a fair price--I highly recommend Premier Drivetrain to anyone needing drivetrain or transmission work done right. read more
