"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."

"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!"
