You know its been a while since I have posted anything. People keep in mind we repair standard semi truck transmissions & differentials. We do lots of driveline vibrations problems. Have them repaired before it does more damage. We certainly do a lot of clutch adjustments. Don't be a victim of having someone else do your clutch adjustment's & then have to have us adjust it the right way. We are experts at this. Call us for an appointment & maybe you can just come by & wait for your truck to have it done. We also do free estimates as lone as we don't have to take them apart. Free road test to help diagnostic work. We will do anything to help. Just call Casey or Mitch & will help you anyway we can. Thank you for your trust in us! 303-423-8204

So far We at Mile Hi Truck Transmissions inc have been able to miss most of these tariff fees' but it is challenging. 3 week ago we spent a coupled of days as we tried to find a pto pump for one of our customers & 3 different vendor & 3 extreme different prices & we said why. They have to come from overseas! Tariffs? Incredible that we can't find in the usa. What are you suppose to do so we ordered the original pump from overseas & got the job done & it works. I think the old days you could buy this pump for 5 to 7 hundred dollars. Today $5000.00 dollars, Crazy huh! 2 other vendors $11 thousand dollars & another vendor $15000.00 dollars. Look out world here it comes. Buy the way, None repairs them anymore. I think this is the first time in my career I have run into this kind problem, Scary to think this might happen again. Thanks to our great customers the believe in us & tolerate these problems once & a while. Blessing my friends!

You know it's been a while since I have posted anything so I'm thinking today It would be a good day to be grateful of how busy we are & having the great help from Casey, Justin, Larry & Cameron & Trudy. After all they do all the work around here. I just like staying ahead of them with parts, Taking units apart before they get there hands on them. Fixing equipment, prepping floors for them to get dirty. Ha-ha. Also Grateful for the wonderful customer we have & there support with our company. We at Mile-Hi Truck Transmission will always strive for perfection in our workmanship. I promise! Thank you all, Mitch Mustard

You know I was just thinking today! Lol, A lot of people don't know what we really do & or that we sell parts for semi truck transmissions & differential. We have complete units & or we can rebuild your transmission or differential. We are a quality rebuilder shop & do removal & installation. We don't buy other company's units. We fix yours. Reason why? You don't know what your getting for quality in there units. You get an itemize bill that shows what you are getting in your transmission & or differential with us. We also do clutch jobs & driveline or vibration work. We care unlike most people or shops anymore. With us you only do it once where as others you may do it multiple times which cost you more! We are not the cheapest but We are the best! If your having problems call us for a free estimate. Thank you We appreciate your business.
