You Guys Rock

Here are a few pics of the car on Day 1 a few weeks back. The car is fast and the new transmission is amazing! I love the direct drive and there is noticeably more ponies to the rear wheels under throttle! I had to increase the jet size in the valve body to get it to idle in gear but it was easy and the tech support at TCI was awesome.

Again, you guys rock and I am very fortunate to have your support, not to mention your craftsmanship and quality staff are second to none!

Thanks again, will keep in touch.

Generosity & Customer Service
Dave, Troy, Kevin & Staff,

Hello, my name is Shawn Lowe and outside my career and family, my passion is racing stock cars. I grew up around oval track racing with my dad in the 70s and 80s and in 2009 I finally took the leap and got involved in it myself as a car owner and driver. In making my dream become a reality, I was going to need sponsorship and people to support my passion. One of my first sponsors was… you guessed it… National Transmission at 4701 Macleod Trail S Calgary. This amazing team of professionals came on board with us and built us a bulletproof Powerglide transmission in which we still run without issues to this day! We have raced both dirt and recently 4 seasons on asphalt and upwards of 6500 RMP and this transmission has been absolutely flawless!

The big things that really jump out for me with this National Transmission location are the staff and the cleanliness of the shop! I have had the pleasure of dealing with three individuals here who always took the time to ensure any of my questions were answered, and that all work being performed on my transmission was top notch, clean and ready for the track. I can honestly tell you from my experience, shortcuts are not an option with this team of professionals and they stand behind their work 100%. The fact that National Transmission is still one of my primary sponsors on my car makes me proud, and I can’t thank this location enough for all they have done, and their unmatched generosity and customer service.

This season, we went on to WIN our first ever ELITE STREET STOCK CHAMPIONSHIP and couldn’t have done it without such an amazing, standup transmission, your expertise, advise and all your support! I would sincerely like to specifically thank the following individuals for this:

• Dave Williams
• Troy Sanderman
• Kevin Walker

I do, and will continue to refer people to this location for all their transmission needs, as this is in every way of the word ..... the “best of the best” when it comes to great customer experience!!

National Transmission Went Above & Beyond

I would just like to thank Dave Williams and the staff at National Transmission on McLeod Trail at 46 Avenue SW for your assistance in helping us replace the flat tire for a 94 year old woman. She was extremely grateful for everyone’s help as are my partner and I. Not only was your lot a safe place to change the tire but assistance from your crew enabled us to get this sweet lady on her way much quicker... not to mention get us out of the rain. Thank you again, you guys went above and beyond!

Thanks Again,

Will Recommend to Anyone

Took my Jeep Grand Cherokee Hemi there for a transmission service. Great service, very clean shop and they saved me $150 compared to Mr. Transmission and the dealership. Will recommend to anyone.

Prompt, Timely Service

I brought my older Ford pick-up in after it wouldn’t shift into gear one morning. I knew there was something wrong with the clutch but I wasn’t sure exactly what it was. I got it towed to their shop that morning, and Troy called me at 2 o’clock that day with a diagnosis and quote. By 2 o’clock the next day it was ready to pick up. They did a great, timely job, and clutch feels excellent. Thanks to the boys at National!
