“H&M Transmission- especially Steve & Paul!

Thank you for all of the work you performed on my Ford Escape. I was nervous to bring my vehicle all the way to Castle Rock from Black Forest but my retired Army friend highly recommended you. I am so glad I did. Your estimate for all of the work was less than two other shops in Colorado Springs; you went to the trouble to get me two rebates on a water pump that went bad that was installed by a shop in Monument and you recommended tires that were cheaper than the ones I was prepared to buy!!! I’ll be back soon for body work!!! Last but not least, the car runs like a dream, thank you!!!”

“H&M Transmission-Mike and Paul,

The two of us together would like to personally thank you for your generosity during Larry’s recent accident and recovery. The flower arrangement you had delivered was spectacular!!! Our home was filled with beauty and amazing aroma. Loved it! It brightened up some of those gloomy days and brought us so much joy. We are so blessed and thankful for your support and friendship.”

“Dear Paul,

Just a quick note to say thank you to you and H&M for all you have done for me and my truck. I always hate having car problems. Not only is it inconvenient and expensive but I feel so vulnerable like I have this monster sign on my forehead that says “ignorant sucker!” when I walk into a repair shop. You have changed all of that! I trust H&M and I know I won’t be taken advantage of, I have such peace every time I call you not only do I know you are able to fix anything that’s wrong but you will do it reasonably and make it as convenient as possible for me. My only concern when I come to you is that I take advantage of you! You are fair and reasonable to a fault, taking such care of your customers I feel guilty! Thank you for always going out of your way to truly serve your customers. I wouldn’t do business with anyone else!! Thanks!”



Thanks again for checking out my F-350 this week. I have already told several people how well you treated me and I am happy to recommend you anytime.”

“Dear Paul and Mike,

“303 Technologies, Inc. has been working exclusively with H&M Transmission and Automotive since their inception over a year ago.. We have been very pleased with the consistent quality of their work. In the entire time H&M has been working with our corporation, we have had no complaints. H&M Transmission and Automotive services our fleet of technician trucks.

H&M Transmission has done an excellent job of consistently meeting their delivery times for us. We normally allow 3 days for automotive repairs. I cannot remember any occasion that they have disappointed us. We are very happy with this consistency.  We are also very please with the referral feedback we receive. We have received several phone calls and letters thanking us for the referral to such a quality repair shop. They have always been very professional to deal with. Prior to the inception of H&M Transmission and Automotive, we always went to wherever Paul Harris was employed. Paul has earned our trust and loyalty for well over 4 years and counting. I highly recommend H&M Transmission to anyone needing their services. I can do this in full confidence that the repairs will be completed in a quality and timely manner.”

“As and owner of a foreign car and new customer to H&M Transmission and Automotive, I trust in the work you did on my car and the additional recommendations you made for preventative maintenance and care. Your facility is very customer-oriented with satisfaction guaranteed. During my last visit to your shop, you serviced my vehicle with little cost, saving me possibly hundreds of dollars. Your mechanic was extremely knowledgeable about additional maintenance needed—this care was beyond my usual dealership service. I was confident that when I departed your shop, my car was properly repaired and ready for the road. Thanks!”

Reggie A.


It’s not often that I take the time to send a note of thanks for someone fixing my car. This time I wanted/needed to. I can’t explain my initial frustration with my vehicle and the lack of knowledge mechanics displayed while trying to find the problem. You took the time after the shop closed to make sure my vehicle was running properly to get me to my destination safely and without incident. For this I am greatly appreciative. Many, many thanks.”


“Dear H&M Transmission, Thank you so much for giving me an add-on. I work very hard with my animals, putting all my time and effort into them. Thank you again, I really appreciate it.”
