They were helpfully informative with their diagnosis and repair plan. They took care of finding good quality parts while ensuring that the job was completed in a timely manner. I was back on the road before I knew it! For context, I went with this after receiving a ridiculously high quote from a different shop. This place offered me a reasonable price while giving me a piece of mind.

Stopped in to get the pump and nozzles for wiper fluid fixed on my tractor. It was a weekday…read moremorning and they were able to pull me in and start working immediately. It took a little over an hour. Pros: quickly serviced me and quickly got me out of there in about an hour. Price on nozzles was pretty good. Cons: price on the pump was meh. A week or two later, the line to the wiper nozzle got disconnected because it wasn't long enough and there was too much tension when using the wipers. I had to reroute the line and secure it differently in order for the line to remain connected with regular usage. Really simple fix, but I just paid someone $300 to have my wiper fluid system in good working order. This shouldn't have been an issue... and my line is still pretty short. I just had to work around it. If I wasn't using the company card on a company truck, I'd have saved myself $240 and done it myself.

I experienced what I assumed was transmission problems while driving through Fontana, CA. in Nov 2025. I was driving a 1999 Fleetwood Pace Arrow with the Ford V10 F-53 chasis. Good Sam towed me to J&L where it was discovered that my flywheel had broken. They jacked up the front end & backed the transmission off so they could get to the flywheel. in doing so they broke a cooling line and spliced it instead of replacing it. They installed the wrong flywheel then left a main transmission wiring harness unsecured which allowed it to fall onto my header and short out three solenoids in my transmission causing catastrophic failure. Additionally, the compression fitting that was used to splice the cooling line leaked so they shoved an O ring in it which eventually clogged the line causing further damage
