Thank you to Brock and the staff at National Transmission (14th Street N.W.location.) They were very helpful and educational! Brock explained the problem with my 2009 Rav 4 was a broken viscous coupler (and yes I know what that is now as well as it's function). My car runs beautifully…

National transmission was so helpful. They were able to take the time to do a diagnostic check right away and they fixed the problem by the very next day. I appreciated Brock's friendliness and professionalism. I would definitely recommend taking your vehicle to them. I will defintely go to National…

Brought my 2005 Civic here because of a recommendation from a friend. My car was skipping from 1st to 3rd gear. I was worried I would have to get a new car because a transmission is probably worth more than the car. The front end and back end service was…

Brock is amazing to deal with! Such great customer service and turn around. Customer for life! Thanks guy's

Pricy but thorough

I had a great service experience when I brought my RV here. The staff communicated well and completed the work in a timely manner. Later, when issues occurred with the repaired transmission, they corrected the issue, no charge and no hassle. I would definitely get transmission work done here again.

I was having shift problems on my 2006 GMC truck. I thought for sure I would need major work or maybe a rebuild. I brought it to National to let them diagnose it. I left the truck there in the morning and got a call from Troy in the afternoon…

Have had lots of work done here, great service, very knowledgeable and they stand by their work big time. Great all around shop and always money well spent.

Great to deal with, highly recommended

Darryl was very informative and upfront about everything. Hopefully not any time soon, but I will be back for any and all transmission work I may have in the future. VERY FAIR in all aspects.
