Customer Testimonies

KNC Trans Parts Co.
(Cookeville, TN)

"Before starting my own business, I spent the last 29 years working for the world's largest high volume torque converter rebuilder in the industry. For 22 years, I was the Eastern Divisional Sales Manager overseeing 26 sales staff. I left that position for several reasons; one of them being the decline in the quality of Product I sold.

Precision of New Hampton owners, Dennis & Leslie Hansen, as well as all of their employees, are committed to producing a high quality torque converter. Precision has the most knowledgeable sales and customer service staff in the industry. My company has sold over 8,000 Precision converters during the past ten months. We are happy to say that our warranty rate is wonderful. It is a pleasure for me to go into my customer's transmission shops and find happy owners, builders, and R & R staff. They are happy because of the high quality of Precision converters. High volume torque converter rebuilders today use 1970 to 1980 technology. Over the past decade, Dennis has had the foresight to position his company, Precision of New Hampton, into the mainstream of the 21st century with a high quality product. Precision of New Hampton, without a doubt, is the best out there."

"Since we switched to Precision converters, our comebacks have virtually disappeared. We are able to give a 3 year 36,000 mile warranty on our rebuilds because of our workmanship and confidence we put into the highest quality parts that are available to us. That's the reason we use Precision.

The sales staff at Precision are really easy to talk to and very helpful. They always have answers to my questions. Other converter companies that I had used are not only inconsistent with part numbers and information but truly pale in comparison when put against Precision in overall service."

"When salesmen come in trying to sell me their brand of torque converters, I just tell them I use Precision of New Hampton, Inc. torque converters. The conversation usually ends there with them saying 'they just can't compete' with Precision of New Hampton, Inc. Hands down, you are the best torque converter company we have ever used. You care about your product and your customers."

-Jeff McLeod


A&F Transmission
(Gonzales, TX)

"I just wanted to tell you and everyone that we LOVE your product and will not buy any other brand of converter. I will wait DAYS for your converter over putting in any other brand. Before using Precision converters I was having 1 out of the 10 jobs that were coming back. Once switching to Precision and adding a Hot Flush machine I have had 1 and that is since November of 2012. The first time I used the Hot Flush machine, it 'made a believer out of me.'

The ONE time we had an issue w/ a converter I was so impressed with the customer service I received when dealing with the issue as well as how quickly we got the replacement.

I recommend Precision of New Hampton converters to everyone and anyone. I love your product and my life has got a lot easier using your converters"
