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

Your business phone number was going to vm for weeks vm full sent emails to your business email address that says no longer in service then email went through weeks later no call backs no return calls have text messages outgoing and incoming including pictures from mechanic your work phone and another phone number he was communicating from. I am very disappointed because when Alberto and I spoke earlier in the year I advised him of the purchase I would be making and the repair it needed and was assured that his mechanics would do a great job as I was confident in their integrity and their work ethic. Noone has returned any of my calls the mechanic stopped answering refusing to return my vehicle and I've been disrespected and disregarded now I am forced to take legal action against you. I left a review on their google business page a month ago someone hearted the message but never responded as the owner often replies to reviews left. The business number is still the same goes to vm and has been since 12/2025. Sent a demand letter with a packet of proof that this busienss was in possession of my vehicle that was returned at this point a lawsuit is the only move to make. God will work it out for me. It's pretty disgusting.

I hadn't done it before, so I asked if I could hang out, watch and learn so I at least know what's going on inside there. Well my wheels didn't have nearly enough grease from the factory so it's good I had them come by, they replaced bearings and adjusted brakes, I'm confident in their work and know I'm safe on the road. Legit the kindest people you could ask for, thorough and know their stuff. I ask questions, they can answer them and explain what they're looking at and looking for. There's a reason their reviews are great, this is who you want to take care of your vehicles.
