Glad I Called Auto Power Source LLC
Daisy, with Auto PowerSource LLC made my experience great with the information she provided to me from start to finish of my purchase of an engine for a 2015 Mazda 3. I informed her that I wanted an engine with low miles ready to drop in the car without transferring parts off my old engine.Daisy delivered exactly what I asked for. A 52K miles engine that runs nice and smooth. I’m still smiling about the product Auto Power Source LLC delivered to me. If someone is looking to buy a used engine call Auto Power Source LLC FIRST!! From Jimmy

This is a scam of a business
I thought this would be a quick honest transaction when purchasing a transmission on 06/03/2026. Unfortunately i was dealing with Daisy on phone calls and Catherine via text, While Catherine let me know they would be pulling the transmission and getting it sent immediately, 06/08/2026 - Daisy was informing that my engine had low compression and would not be able to be shipped, but they have another engine that does work for an additional $428. Mind you I've already paid and Oh Yeah I had ordered a TRANSMISSION. So when i clarified with Daisy, she apologized and told me that was engine for another customer with the exact same VIN. Yet the do have another transmission for an additional $428.
They did refund my money and offer me A $100 store credit on my next purchase.

Hi Joe,
Thank you for taking the time to share this, and we're sorry the experience fell short of what you expected. The mix-up between your transmission order and another customer's part is not the standard we hold ourselves to, and we completely understand the frustration that caused. We're glad our team was able to process your full refund right away, and the store credit remains available should you decide to give us another opportunity down the road. If there is anything else we can do to make this right, please reach out to us directly — we would welcome the chance to earn back your trust.
This engine is missing the distributor, sheet behind Clutch is bent , two bolts in head broke off. I think I can save the engine , but I really paid too much !!!!! Service and shipping was good.
Reply from AutoPowerSource LLC2026-06-06
Thank you for your feedback. I'm glad to hear the service and shipping met your expectations.
I apologize for the concerns you've encountered with the engine. The missing distributor, bent dust shield behind the clutch, and broken head bolts are certainly not what you expected. We'd like the opportunity to review these issues and see what we can do to help.
Could you please send us a few photos of the missing distributor area, the bent shield, and the broken bolts? Once we receive them, we'll review everything with our team and work toward a fair resolution.
We appreciate your business and look forward to assisting you.

Excellent!!!
Was nervous ordering a new engine online from a newer company offering free shipping. Both agents I worked with kept reassuring everything was fine. Engine was received in great condition about a week-and-a-half after paying. Dealership said this is the nicest looking engine they have ever received with all the components attached in working order, including the cables. Daisy and Catherine were easy to work with. Only reason for the missing star is the delivery timeline was longer than advertised. It is about a week of processing before it ships out. Once shipped, it will arrive in 3-5 days.
Reply from AutoPowerSource LLC2026-06-06
Thank you so much for your detailed review and for trusting us with your engine purchase.
We're thrilled to hear that the engine arrived in great condition and that your dealership was impressed with its quality and completeness. It's especially rewarding to know that Daisy and Catherine were able to make the process smooth and reassuring for you.
We also appreciate your honest feedback regarding the delivery timeline. You're absolutely right that processing can sometimes take longer than expected before shipment, and we're continuously working to improve our turnaround times and set clear expectations from the start.
Thank you again for your business and for taking the time to share your experience. We truly appreciate your support and hope to serve you again in the future.

I was looking on line for a good used engine. Auto Power Source popped up. I did a little research and they are legit. I called them and spoke to Daisy told her what I was looking for. She took care of everything from finding and locating an engine to helping me check out. She also stayed in close contact with me to let me know things were a little held up but would moving along soon. She went above and beyond. Because of her I will be doing business with them again on the near future as I replace the engine in my Titan soon. Thank you so much.

I have been pleased with the service I.
The first transmission wasn't usable so they processed a replacement quickly with no extra charge.
I would do business with them again!

After researching several companies
After researching several companies, I decided to go with Auto Power Source. Daisy was fantastic to work with—she stayed in constant contact and kept me updated once the motor shipped. Even when I had a last-minute request to change the shipping address, she responded immediately and handled it without any issues. The engine has arrived, and I couldn’t be happier with the purchase!

"Research paid off — and we're so glad you chose us! 🙌 Daisy is an absolute rockstar, and this review is a perfect example of why.

We'll make sure she sees this! Now let's get that engine running and enjoy the road ahead! 🚗⚡🔧"
