testimonial hand written

"We're the family from Moberly who was in St. Louis on June 17th who had the broken axle on our mini van.

We first wanted to thank you again for getting us on the road so quickly. The rest of our trip was great & we got to see our Cardinals win."

"I am writing you to recommend Quality Transmission Service 5944 Arsenal St, St. Louis, MO 63139 for an outstanding job of diagnosis (a rumbling sound from the transmission) and promptly correct it at a very reasonable cost.

This is an honest company that I enjoyed doing business with and I highly recommend them to anyone with any transmission problem."

"There really are some good people in this world. Thanks for trusting me."

"Thank you for taking such good care of me & the 442!

I am lucky to have been introduced to such fine folks, not to mention a great business.

Let's build & install the "Big Daddy Tranny" next winter. I am saving for it now."

"I wanted to thank you for dropping what you were doing and take care of my car (the Mach I) on March 4, 2005. I cannot explain how much appreciation I have for your help in this instance; it is difficult to find skilled experience and honesty these days.

Thank you for providing me honest quality throughout the past decade. I included a gift certificate for my gratitude and figured we could all use a little more in the fridge."

"My wife and I were in St. Louis last month visiting our daughter and family, celebrating the arrival of their second daughter at Barnes Hospital. The day before we planned to leave for our home in Texas, our 1989 Ford developed a transmission problem.

Our hats are off to Pat Walsh at "Quality Transmission Service" for his superior code of ethics. There are still a lot of good people in business places even if we had to drive to St. Louis to find one."

"It is extremely encouraging to find anyone as skilled as you and that is extremely honest and fair.

We definitely would recommend Quality Transmission to anyone who needs transmission work."
