I ported the heads and intake manifold in my motorhome a few years ago. Within a year after, I literally hamburgered the transmission. I saved money for about 6 months and got Bruno and Arash to do a modified "Bomb proof" build. It costed more than I anticipated. But it was well worth it!

My family is visiting Calgary for a vacation, the day before we are suppose to hit the road back home, my vehicle wouldn't go into gear and not drivable. National transmission popped up in my google search and were close to the hotel. I called them at 7:30am explained my problems. They said we can move some vehicles around and get a spot for you. They got vehicle towed and fixed by 2:30 the same day. Then they came and picked me up from the hotel so I didn't have to get a cab there. They also have a good sense of humor!! Which is always nice when you are not having a great day. I was born and raised in Calgary before moving away. I wish I found this place years ago! They saved our vacation!!

Decided (nervously) to have my F150 transmission serviced for the first time today at 257,000kms. I called before hand asking for some expert advice. Arash was very friendly and helpful, and didn't blow off my silly questions. He also didn't sugar coat the possible outcomes which I appreciated. He kept me updated throughout the process and had my truck back to me in no time. So far so good! Edit: 3000kms later, truck is smooth like butta

Was referred to this location by OK Tire in Airdrie (who are very trust worthy folks) a few months. Came to National Tranmission (NE location) for transmission issues (leaking fluid, etc.). They were very affordable and I had my car back within a few days despite them being swamped. Owner (Arash) was very friendly and consistently called with any updates. Would recommend.

Had the transmission in my 2003 Ford Explorer rebuilt there 100,000Km ago, and said I would leave a good review if I got to this level of additional mileage. Transmission is working well, and I am changing the fluid/filter every 48,000Km to help maintain it. The only reason I couldn't leave a full 5-star review is due to problems I had after having it serviced at their Red Deer location. I had about $1,500 in work done there in the fall of 2015 (after which it was working fine), but then a pretty-major break-down in March of 2016 (to no fault of my own), which led to the above work being done. The Red Deer location had by then been closed due to the downturn in the economy, but at least at their headquarters National was willing to credit me about 80% of that last bill towards a full rebuild. Hopefully it will keep working well, as I would like to keep running this vehicle for awhile yet! If it does I will post an update to this review in the future.
