Customer Testimonies

(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."
