Nielsen's Engines and Transmissions

Just had a clutch done something failed on way home.. (was MY work,clutch itself felt great) clutch master cylinder came out of firewall, again not their fault I replaced days before. I showed German what was doing after hydraulic replacement, anyway, pressure plate failed. Replaced everything but hydraulics, They still sent someone to help get me moving again. Previous work was also excellent highly recommend. 340,000 miles ready for more

I am so incredibly grateful to have found this auto shop. As a single mother, I've always been apprehensive when dealing with car repairs, constantly worried about being taken advantage of. German completely changed that experience for me. He was patient and respectful, taking the time to show me the issues with my car and explaining everything with total clarity. He earned my trust by not proceeding with any repair without my explicit approval. It's a wonderful feeling to leave a mechanic knowing you were treated with honesty. This place is a true gem in Hesperia. A mechanic this good is deservedly in high demand, so while there might be a wait, it is absolutely worth it for the peace of mind.

The place is the only one that i know throughout all my life that is super honest, and very knowledgeable mechanic to be able to fix engine, transmission and more. the owner and staff will treat you with respect and professionalism, and super Friendly too. Im amazing about there pront response to fix what your car may need. I do recommend them with my eyes closed big time, not to mention the secretary Jackie she's very professional, with lot of ethics, and care to help you with your car troubles. Just amazing auto repair shop, wonderful. MAE

I took my 2000 Ford Mustang GT to German because it had an oil leak, another mechanic to me I needed to rebuild the engine. German found a ripped gasket and repaired it. Trustworthy mechanic, he did and excellent job and would highly recommend.

Took my truck in for a rack and pinion replacement and these guys took care of me pretty well. Took about a couple of hours and the truck was pretty much good to go. I needed the truck back asap and they got it done. Great price too. Not gouging the customer. There was a small hiccup with a seal that broke during installation, so they requested I bring it in as soon as possible and fixed it right away, no questions asked.
