What Our Customers Say
“We have been having all of our transmission work done at Pfeiffer Transmissions for the past 25+ years. No matter where we are, if we have transmission problems, our vehicle gets towed or driven back to Pfeiffer’s. They are totally reliable, reasonable in price and great to do business with. Their knowledge of transmissions is far superior to any other transmission businesses we have used. Go with Pfeiffer’s and you will be totally satisfied.”

“I have never had a sense of complete trust with repair garage until these guys. Tim and his crew are the best. I recommend them to anyone.”
