Very friendly and honest service. They were able to take my truck the next day and called me when it was getting looked at. They even called me to let me know of an issue that arose and asked me how I wanted it handled before going ahead with the repair. Very happy with the service they provided and I definitely recommend them.

Great, knowledgeable professional shop I brought my 2010 Nissan Titan Pro4x 4x4 in for a slight, occasional 'slip' when accelerating. The Service Mgr took my truck (I was along as well) for a test run with a diagnostic computer attached to monitor performance; No charge. Then put my truck in the shop to do some physical checks. Found no leaks but that the transmission fluid level was down about 2 litres (previous service ??). Additionally found was a front differential pinion seal leak. In aditional discussions, it was realized that the transmission had only been flushed previously & not fully serviced, and was nearly due for a full servicing. After presentin the findings, The Service Mgr provided a repair estimate & the truck was booked into the shop for the following open business day with an estimated repair time. Additionally, a technician was instructed to add a litre of correct oil to the transmission to increase the level to closer to where it should be; No charge. The day of the repair, the truck was delivered to the shop at the appointed; the repairs were completed within the estimated time AND the invoice was less than the estimated price. All-in-all; a great professional knowledgeable shop to deal with!! AND a great service experience altogether. LSA

National Transmission is the repair shop to go in Calgary for first rate service and attention to detail. Arash was great in explaining the repair process and the work was done in a timely fashion. My tranny shifts as smooth as silk and I am very pleased. Keep up the great work Arash, Neil and the rest of the crew!

Neil, Arash and the team at National Transmission (2432 23 Ave NE Calgary) are awesome! I needed work done on my BMW X5 and they got it done it done FAST and PERFECT! And not only did they get it done with great professionalism, they also did some research on my vehicle to answer questions I had! Ladies, if you are looking for some honest mechanics, this is the place to go!

Neil and Bruno are the only ones I will trust when it comes to my drive line and transmission needs, I had my transmission rebuilt and was very happy with the work and how everything was handled, I ended up having to replace quite of a few other things along the line but they were always things that were related to the work and what I asked to have looked at, It was nice to have the guys save the parts for me so they can show me why they needed replacement, You are in good knowledgeable hands with these guys.

I own an automotive repair shop, and Brock & his team are my "secret weapon" when it comes to transmissions. Brock really knows his stuff and chances are, if I call him about a transmission problem, he's seen it before. He makes us look like diagnostic all stars because I haven't yet come across a difficult transmission problem we couldn't solve together. In many cases, using Brock, I can offer my customers a better quality repair than even a brand new transmission would provide. This is because he will go a step further than just repairing the transmission, and will often improve or "beef up" the common problems or weak areas as well.

They were very prompt and professional and fixed the transmission perfectly. It's been almost a year and the transmission is still working great. The only nitpick I could possibly put against these guys is that my car smelt like oil inside for about a week afterwards. A little airing out of the car might be in order.
