Transmission diagnosis and repair

"You need a transmission" is the most expensive sentence in the shop, and it's wrong more often than you'd think. We diagnose the actual failure first — sensors, fluid, valve body, wiring — and only recommend the big job when it's genuinely the big job.

What customers say

★★★★★

“NCR Performance is a rock solid business. Local team that is simply passionate about cars. They are extremely honest, fairly-priced and provide top tier quality work. The owner even took the time to initially speak with me over the phone during off-hours (very in-depth) about a range of issues I'm experiencing with my car. I highly, highly recommend these guys to anyone. Fantastic local business. Thank you NCR team.”

“NCR absolutely knows his stuff. He helped me force regen my truck and took the time to really talk through what was happening, not just rush the job. We went over upgrades that actually make sense for long-term reliability and performance, not just hype parts. It's clear he's passionate about what he does and understands these trucks inside and out. If you're serious about doing things right, NCR is the guy to go to. Highly recommended.”

“Cannot recommend this shop enough. Was on a trip from Salt Lake and transmission went out on the side of the highway. This place went above and beyond to get me up and running. Gold standard of shops, Nic deserves the success”
