These guys did the suncoast performance kit and trans-go shift kit build in my GMC Duramax with a 5 speed Allison transmission. They had a great turnaround speed and the price was the best out of four other shops in Houston and the surrounding areas. I looked around and researched for about two weeks, and found national transmission. they kept me up to date and asked before replacing any parts and gave me options. I would recommend them to anyone looking for a build on your transmission.
