The PNH Difference: High Quality & Dependability

We are true torque converter professionals. We do not just cut open used converters and weld them back together and call it good enough. If you want hasty, cheap, low quality converters—then PNH is NOT for you. Show More

How PNH Brings Relentless Quality to your Torque Converter:

  • Every single torque converter processed in our facility goes through an exhaustive checkpoint protocol to find EXACTLY why it failed.
  • Next, we implement numerous corrective actions to fix common failure points for each specific model. We see more torque converters in a single day than most competitors see in a year; which gives us a tremendous amount of insight and statistics to fully understand OEM design flaws. In addition to failure point corrections, we get to the root cause of the problems and implement changes so your torque converter lasts.
  • Converters are then thoroughly rebuilt with all the new and necessary corrective actions in place; ensuring future breakdowns don’t occur!
  • Precision is not just our name, it is what we do. The tolerances that we maintain during the rebuild process ensure you are getting the best of the best.
  • Our facility sets the bar on technology and process flow. Every single converter is built to exceed your expectations. Brand new components, high production efficiencies, so you get more for less.

When you get a torque converter from Precision of New Hampton, you are not getting "just" a torque converter! You are getting the BEST of the BEST!

Customer Testimonies

Bozeman Transmission Center, Inc.
(Bozeman, MT)

"As many of you know and have experienced, problems with torque converters can be frustrating and costly in more ways than just the money side of it. We, as shop owners, get to deal with that customer face to face, or worse yet the customer who has left your area and is now broke down. Not to mention down time, a bind in your shop's work flow and everything that goes with a converter failure. I have owned B.T.C for 20 years with 30 years in the business. Since I have started using Precision Torque Converters almost 10 years ago, my torque converter problems have dropped dramaticly.

What I like besides the service and quality is the fact they are constantly improving their product line. They genuinely care about their customers. With A.T.R.A.'s new and longer warranty program I feel completely at ease installing Precision Converters in our units. Simply put, you couldn't offer me enough money to change supplier's.

After 30 years in this business, I know what works and what does not, and Precision Torque Converters work."

Brown's Auto Service, Inc.
(Billings, MT)

"I know you don't get this very often but I just wanted to take the time to let you know that you have one very happy customer in Brown's Auto Service, Inc. Milt Freese and the rest of your crew do an excellent job of making sure of that. We have been using your converters now for almost 14 years. Over the last 48 years of rebuilding transmissions we have used many different converter manufacturers. Never before have we used one for 14 years. In an industry where the converter is blamed for more than its share of problems, you have listened to our issues and helped us to resolve them in very positive ways.

Our goal is not to become a transmission company that sells the most units, has the most builders, or even one that has the lowest price. We would rather be known as a company that sells high quality products and services. To achieve these goals, we have had to form strategic business alliances with vendors such as yourself to assure that our customers are getting the highest quality product available.

Our philosophy is different from many in our industry in that we believe that price is not the most important factor in the selling of our repair services or our transmissions. Our business philosophy focuses on four main areas - CRAFTSMANSHIP, PARTS, SERVICE, & LOYALTY. To be able to live up to this business philosophy we live and die based on the relationships we develop with companies like yours. Needless to say because of the strategic business alliance we have with Precision, our company has been doing extremely well.

Over the last ten years most companies in our industry have merged, gone out of business, or just simply disappeared. It is very reassuring to know that Precision of New Hampton has been there for our company and will continue to be there tomorrow. Once again thank you for the great service that your company provides our company."

D and E Automotive Products
(Toledo/Holland, OH)

"I've been in the automotive industry for 20 + years. Seen a lot of companies come and go, even worked for a few of them. To do business with a company that stands behind their products is reassuring to us as a supplier and is the best insurance any shop could ever ask for.

We've HAD other converter suppliers, that's past tense for a reason. When I ask my customer if they would rather wait for a Precision if I do not have it in stock, most prefer to do so. Their ability to get me next day service helps keep my inventory from growing on hand to find units, the quality second to none.

I used to have two bins before, one for cores, one for defects. Not any more, my customers see the quality they know we stand behind what we sell and so does our supplier. Tech bulletins, tech service, and a quality product that has helped reduce our warranties to virtually none. Price is only an issue to someone who can afford to do it more than once.

The bitterness of poor quality persists long after the sweetness of low price is forgotten. That's how you determine value."
