Slipping, hard shifts, a delay going into gear or a warning light. We find out what's actually wrong first, then tell you whether it needs a service, a repair or something bigger.
Transmission service covers everything from checking and changing the fluid to tracking down a shifting problem and repairing what's causing it. An automatic transmission relies on its fluid to shift, stay lubricated and stay cool, so a small problem like a leak or worn-out fluid can turn into a big one if it's ignored.
It matters even more around here. Mountain grades, towing and long climbs keep a transmission under steady load. That load makes heat, and heat breaks down transmission fluid. Once the fluid can't protect the clutch packs and other internal parts, you start seeing slipping, delayed shifts and eventually internal damage. Catching a problem early is often the difference between a service or a repair and a much bigger job.
Our approach is to diagnose before we replace anything. That means checking the fluid level and condition, scanning for stored codes and driving the vehicle to feel what you're feeling. On modern vehicles, a lot of shifting problems come from sensors, wiring, solenoids or the fluid itself rather than a failed transmission.
Once we know what's going on, we'll tell you what we found, what needs attention now and what can wait, and what each option costs. Work doesn't start until you've given us the go-ahead. If there's internal damage, we'll explain whether a repair, a rebuild or a replacement makes the most sense. We do all three.
We diagnose first

Another shop says it needs a new transmission? Bring it in and we'll look ourselves.

Excellent Service! I took my car to them for a full transmission fluid flush and refill, brake fluid full flush and replace, and an oil change. These are Good People. They do Great Work for a Fraction of the Price the Dealership wanted to charge me. They are now my go to shop.

We had our Nissan Titan's transmission replaced here, and we couldn't be happier with the experience. After getting several quotes from other shops, their price was much more reasonable without sacrificing quality. From start to finish, the staff was upfront, honest, timely, and thorough. They kept us informed throughout the process and delivered exactly what they promised. A special thank you to John and Kyle for providing outstanding customer service. They made the entire experience stress-free and went above and beyond to make sure everything was done right. Our truck is running great, and we couldn't be more pleased with the work. If you're looking for a trustworthy shop with fair pricing and excellent service, I highly recommend them! Jeff H

Brought my F150 to UCDI to help diagnose a possible transmission issue that another service center told me it needed replacing. It was clear from UCDI that the other shop fell way short in attempting to diagnose the issue. I’d recommended them to anyone looking for an honest service shop. 5 ⭐️

Two companies told me I needed a new transmission and 10,000 dollars to fix, including dealership. I brought it to UCDI and asked them to look at problem and 2.5 quarts too much fluid, I added and a diagnostics done and 100 dollars and I’m on my way. The others didn’t even check fluid levels. Honest and fair and got me out same day. I will recommend that service any day! Thanks
