Fair prices, clear answers, and a warranty behind the work
Our story
Tech Guy Auto is a full-service repair shop on Imperial Highway in South Gate. Tom runs the front desk, and the work behind it covers everything from a routine oil change and smog check to alternators, wheel bearings, air conditioning, and complete transmission jobs. We know a car in the shop is a day off the road, so we make it easy: drop the vehicle off in the morning, and we'll call you when it's ready. Customers tell us the same things over and over — clear communication, fair pricing compared to other shops, and repairs backed by a warranty so you're covered if anything comes up later. Thirty Google reviews average 4.9 stars. That's the standard we work to keep.
What customers say
“Tom and his techs did a good job on my transmission, which helped me get back on the road. Tom is a very respectable guy and communicates well with customers; he even gave me a ride home! I feel I was given a fair price compared to other shops, and the warranty made me feel more secure knowing that I could reach out if anything were to happen. Three months later, the car is running like it's supposed to, with thankfully no issues.”
“Came here looking to get a good price on a wheel bearing replacement and talked with Tom who gave me a great deal and also gave me a great price for an alternator replacement and was able to help me get situated with a payment plan which is great for those who are on a budget but need repairs to your vehicle. Overall i had a great experience here and recommend bringing ur vehicle.”
“I love this mechanic he is very helpful and friendly too me. I brought my car here when I first bought it for a smog check and an oil change and he assisted me right away. He is also very convenient due too me working full time I just drop off my car and he calls me when it is ready for pick up really helpful since I work down the street.”
