Shepherd Transmission Inc.

"If you're in the GTR world, chances you've heard of John Shepard or at least Shep transmissions. His builds are second to none and for their performance and for what you get, unmatched in price. Turn around times are very reasonable, and they'll never try and "sell you" on parts that aren't necessary to meet your goal. He did this with me. I asked about a billet crank, and he said for my goals, it was 100% unnecessary. Just like that, I saved several thousand dollars because he was honest and shared his valuable knowledge. Buy with confidence and buy from the best! Thanks John"

"Great Customer service, and super fast shipping, last week my R35 lost all even gears and after contacting John, he helped me troubleshoot the issue and the parts i needed to get the job done, i decided to do the work myself and even then he took the time to give me a few pointers, i had all my parts delivered to my door the very next day and was able to get back on the road, i will definitely be using him in the future"

"Had a transmission built by them 1-4 ppg with stock 5th gear for 14k. 2500-3000 miles later, fifth gear let loose, split the case to realize it was never tighten properly. customer service said to call Nissan. I think it’s time to get lawyers involved. Don’t waste your money through them! especially since they don’t stick by their work."

"fantastic customer service all around, and a great turn around time on our trans rebuild. highly reccomend"

"The BEST Nissan GT-R transmission rebuilt in the world. Shep and his team make it easy to ship, rebuild and deliver. One of most honest business owners in the industry. Thank you John for all you do!"
