I was very skeptical at first and had to do some research to see if this company was legitimate. David worked with me to provide so references of prior customers. Talking to those references and the reviews of Trust Pilot I decided to give them a try. David , Alan and Daisy were a pleasure to work with. They provided step by step updates through the whole process until the engine was delivered to my Auto mechanics place where the work was being done. I may have started out skeptical, but ended up very pleased with their service.

We totally get the skepticism — engines aren’t exactly an impulse buy 😅 Huge thanks for doing the homework and giving us a shot! We’re glad David could connect you with references and that everything from start to delivery helped earn your trust. Big shoutout to David, Alan, and Daisy for keeping things smooth and keeping you in the loop every step of the way. Starting skeptical and ending pleased is honestly our favorite kind of win 🙌 Thanks again for trusting us — we’d be happy to help anytime you need us!

I love the customer service not overbearing not pushy but consistent and respectful. David was super polite and helpful I will definitely be using this company in the future.

The overall experience was very good. From the beginning of ordering the transmission to receiving it. Communication was good as well.

Music to our ears! 🎶 Thanks for the kind words — smooth ordering, smooth delivery, and smooth communication is exactly the goal!

Everything went as advertised shipping was a little slow because it was around the holidays. I also thought it might be a scam only because every single phone call I get that’s from a spam call, They typically have a Middle Eastern accent and it scared me when I got a hold of my rep, but everything was perfect.
Response from AutoPowerSource LLCJan 16, 2026
Thanks for the honest review—we really appreciate it! The holidays definitely slow things down a bit, so thank you for your patience there. And we totally get the initial hesitation—these days, it’s smart to be cautious. We’re glad everything checked out and that the experience ended up being a positive one. Thanks again for giving us the chance, and enjoy the ride! 🚗💨

If I could give six or more stars, I would. David and everybody there at Auto Power Source has been just wonderful in this trying experience. I had to replace a 2006 350Z engine, and it had the non-rev or the rev engine and it took a minute to ensure that we got the proper one shipped to us. Thank you so much for all your help David and you guys have a beautiful and blessed day.
Response from AutoPowerSource LLCJan 15, 2026
If we could accept six stars, we’d frame this one ⭐⭐⭐⭐⭐⭐ Thank you so much for the kind words! We know that rev vs. non-rev on a 350Z can definitely make things interesting. On behalf of David and the entire Auto Power Source team—thank you for your patience, trust, and positive energy. Wishing you a truly blessed day ahead! 🚗💨
