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

Transolution
(Missoula, MT)

"A quality-built transmission performs only as exceptionally as the torque converter. No matter how superior the workmanship a technician builds into a custom-built transmission, a poor quality torque converter can spoil the works. That is why we at Transolution started using Precision of New Hampton Converter products. We discovered the quality of Precision Converter products back in 2002 after having some costly and embarrassing comebacks due to faulty torque converters manufactured by another company.

What a relief it has been not to experience the hassles of converter failures and comebacks. Precision of New Hampton Converters not only complements the high quality workmanship of our custom-built transmission, but the price is right too, a savings we are please to pass on to our customers."
