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

Booker Trans, Inc.

"The fact that I do not have any problems with Precision of New Hampton, Inc. torque converters and I get free delivery right to my front door is great. I've dealt with a couple of other torque converter companies and they couldn't keep my business supplied with what I needed.

Twenty-five years being in business I like the consistent quality of torque converters Precision of New Hampton, Inc. has to offer along with the consistency on keeping me supplied with what I need.

I feel very confident when I call Precision of New Hampton, Inc. with any questions. They definitely know their product and can assist you with any questions you might have."

"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."

Rod's Transmission Services, Inc.
(Coeur d' Alene, ID)

"Out of desperation and frustration with the torque converter supplier we were using, I found myself actually researching fixes to THEIR problems, which had become ours. I then toured numerous converter plants all over the US and even into Mexico in an attempt to find someone that could give me confidence in their product. After finding Precision thru research and referrals from trusted colleagues, we gave Precision a try. It has now been over five years and I can honestly say I no longer worry about "IF" a torque converter will function as expected. They have sincerely earned my confidence and trust! No torque converter worries is truly a wonderful thing!"
