Had the viscous couplers on my car replaced here. The first part they received turned out to be defective from the manufacturer, but the team handled everything smoothly under warranty. I didn’t have to deal with any of the hassle—they took care of it all. Everyone was helpful throughout the process, and Case was especially friendly and professional.

Highly recommend national tranmission. Prices are great staff is friendly and knowledgeable the work they do is awesome and definitely reliable compared to alot of companies out there Case the manager was awesome, very knowledgeable, and understanding of circumstances at hand, very informative of parts and costs. With over 30 years experience shows in there work ! My Tucson was in for a day and a half Had to wait for a R&R Pinion Seal to show up Swapped fluid on Rear Diff and Transfer Case they also test drive to make sure work is gaurnteed which brings peace of mind. I will be going to NT from now on. Great job, guys !! You saved my Hyundai and my wallet !

It's creeping up on a year now since Arash pass me back the key to drive my 1966 Chevy C10 fleet side long box home, And it's a daily driver now, NOT a trailer queen! It has a GM Performance ZZ454HO crate engine under the hood. I had a goal for how I wanted to be able to drive and use this old school pickup. They upgraded the entire drivetrain bringing it from obnoxious to drive across town to a very relaxed roll down the highway going 120km at 2000rpm and a badass attitude, if desired, off the lights. I had a goal, they planned it, built it and brought a dream to life. But my best take away from the entire experience was the feeling of trust and legitimate care for My goal. "Good people make good experiences stay with you". "Thankyou Arash" and "Thankyou Team". Over & Out, Craig.
