I made an appointment and Ashley, I apologize if I remember her name wrong, welcomed me. I'm handicapped and too short to get into my sister-in-law's truck as I forgot my portable step. Ashley brought out a tire rim they used for a step stool and it worked perfectly! She even let us take it with us so we could do errands while they did maintenance on the van. She called and gave me an update on the work and also called to let me know they were done. This shop is the best! They've helped my sister-in-law with two issues on her truck at the last minute and still got her in and diagnosed the problem.

We stopped in here to get a trailer tire replaced. After they replaced the tire on our spare rim,…read morethey went out to put it back on the trailer. But me being me, I'd given them the beat-up spare to replace, because I was going to swap it out with a tire that had a slow leak. The young man looked at my slow-leaking tire, turned to me and said "It's probably the valve stem. Those high-pressure valve stems suck. Pull it around back and I'll see what I can do." We pulled it around back, and a couple of squirts with soapy water confirmed it was the valve stem that was the problem. It took all of ten minutes for him to pull the tire off, replace the stem, and slap it back on the trailer. So I now have two good tires on the trailer, plus a brand new spare, all at a good price, and all done within half an hour on a Saturday. Holy moly people. This place rocks.

We showed up a day early. He allowed us to overnight in his parking lot until the next day. From the moment we met Scott to turn in our RV, he turned out to be very personable and reassuring. He told us to go and do the "tourist thing" in the Black Hills area (Deadwood/Mt Rushmore) while he and his crew did the inspection and repair. He pulled our RV out of his garage which allowed us to overnight on his property another night while he waiting on parts expected the next day. The parts arrived, he completed repairs (plus an oil change late on day 2 and allowed us to overnight on his property from where we could resume our travels the next morning. I detail all this because as full time RVers it can be difficult to get timely emergency repairs. Bickles gave us great service and piece of mind. I HIGHLY RECOMMEND Bickles. Thanks Scott and crew!

The Transmission Specialists saved me thousands of dollars, and I am extremely grateful to Brian…read more After driving hard through the hills in South Dakota on a very hot day in a 1986 (vintage) Toyota Motorhome, I experienced some mechanical problems. The first place I went to help was Southside Auto Repair in nearby Deadwood, SD (See my very positive Yelp about them). After fixing an electrical issue, I was still concerned about my engine/transmission. Southside referred me to the Transmission Specialists. I went to the Transmission Specialists and their backlog of work was a week out. At the time, I did not want to wait, and sought out another mechanic to fix the issue quickly so I could be on my way. The new mechanic suggested a new transmission and over $5,000 in repairs, My friends, family, and social network advised me to run fast and far from them. (Beware of the Auto Doctor in Spearfish - I Yelped about them.) After sticker shock, and a good night's sleep, I called the Transmission Specialists and scheduled a diagnostic, a week and a 1/2 away, and stayed in a nearby camp ground for about $250 a week. When the day came, Brian test drove my motorhome, checked everything out, and suggested a few minor repairs (less than $500), and some of those could be delayed and performed by another shop. No new transmission, no rebuilt transmission, and no unnecessary repair bills. Thank you, thank you, thank you Transmission Specialists! As a side note, I noticed that progressive technical related-certifications, as well as thank you notes and acknowledgements from the community, graced the walls of the shop. Brian is a very upstanding, honest guy, and sincerely appreciate his knowledge and expertise. You also may wonder why I gave this shop 5 stars, since they made me wait over a week for service. Here is my philosophy on goods and services in general...You may have it good, inexpensive, or quick - pick 2, you don't get to have all three. The Transmission Specialists are good at what they do, and therefore have a wait list, they were also very cost-effective. I was fortunate to have the time to wait for the expertise.

We pulled into an RV park and began the search for someone who could work on the truck. Several local recommendations later we ended up calling Brian at Transmission Specialists. He was backed up with other customers but, since we were broke down while on vacation, agreed to look at the truck to see what he could do. We determined that a remanufactured transmission was the best course of action and Brian recommended two sources. We decided to order one. Took several days to arrive but when it did, Brian put us ahead of his other customers (again) and installed the tranny. We continued our trip to Georgia and returned home to Oregon. Nary a quiver out of the new tranny for the rest of the trip. Brian was courteous and knowledgeable. Highly recommend Transmission Specialists if you are in the area and need service. Thanks, Brian.
