What Our Client's Say...

When my car's transmission started acting up, I turned to Red Line Transmission. They did a great job in diagnosing the problem and provided a detailed explanation of the repairs needed. They completed the repairs with precision, and I'm grateful for their expertise and would trust them with any future transmission issue.

I brought my car in with transmission concerns, expecting a costly repair. However, the technicians inspected my vehicle and informed me that only minor adjustments were required. They didn't try to upsell unnecessary repairs, and their honesty saved me money. I appreciate their integrity and will return for future maintenance needs.

Red Line Transmission excels in not only transmission repairs but also customer service. I highly recommend their services! From the moment I called to schedule an appointment, their staff was very accommodating, patiently answered all my questions, and kept me informed throughout the repair process.

When my car started experiencing strange shifting patterns, they accurately diagnosed the problem and explained it to me in simple terms. Plus, their ability to pinpoint the issue gave me confidence in their abilities. I wouldn't hesitate to recommend Red Line Transmission for accurate transmission diagnostics.

My car was still under an extended warranty, and I needed transmission repairs covered by the warranty. Red Line Transmission worked seamlessly with the warranty provider, they made the process hassle-free for me and ensured that the repairs were completed according to the warranty guidelines. Great service!

Redline rebuilt my transmission while I was on vacation in Idaho. After 14 months and only 6000 miles which was out the warranty timeline, there was an electrical part failure. There was no damage to the actual transmission, it was just a faulty sensor that needed to be replaced. I called Alex to see what the best options were to fix it. I live 10 hours away from there shop, so Alex did all the work finding me a shop close to where I live. Once the shop fixed my truck, Alex paid for all the labor to have the replacement part installed. Its not very often you find a shop that is willing to go that far for their customers. There was no negotiating or anything, he just felt it was right to take care of me.

Had a really good experience with Alex at Red Line. I had a Jeep Wrangler that started making a knocking sound in the rear end. I had other folks that were unable to diagnose it but talking to Alex over the phone he not only gave me a pretty good idea of what he thought it was, he was one of the few mechanics that was willing to give me any sort of quote. While the final price ended up being higher, he was transparent and explaining to me the reason for the increase. Even having the entire rear end rebuilds, I had my Jeep back within a week. It also came with a 12,000 mile or 12 month warranty, everything done.

Compared a few shops for my transmission trouble, and Red Line Transmission won me over. They got the job done without any unnecessary fuss, and the pricing was reasonable. Solid choice for anyone needing reliable service.

After a few bad experiences, Red Line Transmission restored my faith in auto shops. They were quick, didn't overcharge, and the team was genuinely friendly. It's my go-to place now, and I recommend it to anyone needing transmission help.

Red Line Transmission is a paragon of automotive proficiency. The meticulous attention to detail in their diagnosis and subsequent repair is commendable. I appreciated the thorough explanation of the issue and the transparent pricing. This level of expertise is a rarity in the field.
