The whole process was awesome and easy. Just send the VIN and they find the correct motor and the rest is taking care of. A few minor hiccups but they walked me through the whole thing and all taking care of. I couldn't be more happier

The whole process of the purchase went very smoothly. The point of contact was very helpful, attentive and timely when responding to questions I had with the delivery. The engine was well worth the purchase. Works very well. Will purchase again.

So far the experience has been a God Send. A global search for a correct code Audi manual transmission sent me to a fake site, God said check, I did, could've been very regretful. Sarah worked with me, build code and vin, nailed it! Very personable, can't wait to update for the completion!! God Bless
Response from AutoPowerSource LLCOct 24, 2026
Thank you, Michael! So glad Sarah was able to nail down the right build code and VIN match for your Audi transmission — that kind of verification is exactly what keeps people from getting burned by the fake sites out there. We'll be sure to pass this along to her. Looking forward to hearing how the install goes! — Team AutoPowerSource

I would like to say I'm not one to buy online without knowing about the company first hand or knowing someone who has made a purchase from them in the past. Now I would like to say I was scared at first and very nervous but the communication with the team I had was very impressive. They walked me through the entire process and kept me informed along the way and answered any questions I had in a timely manner also let me not fail to mention the engine arrived earlier than expected. They even did a few follow up checks with me after I had the engine installed. I would highly recommend. Thanks you guys are the best!!
Response from AutoPowerSource LLCOct 24, 2026
Thank you for this! We know buying online without knowing a company first-hand can feel like a leap of faith, so it means a lot that the team's communication helped put you at ease and kept you informed every step of the way. Glad the engine beat the estimated delivery, and that the follow-up checks after install gave you peace of mind. We're the ones who should be saying thank you! — AutoPowerSource LLC

5 Stars!! Top tier- service & smooth transaction. I ordered a transmission and couldn't be happier with the process. The team kept in constant communication - made sure to verify the transmission's working order before it shipped. Honest, trustworthy, great prices, and fast shipping! It’s hard to find service this reliable. Thank You! I highly recommend. A M S
