This company will rip you off so BEWARE. My car broke down on Sunset in West LA due to a bad alternator. Being desperate and panicked, I called AAA and they recommended Westside Transmission & Automotive on Cotner in Los Angeles. After I had my car towed to Westside Transmission & Automotive, Steve ran a diagnostic for a $195 fee (rip off) and agreed with my assessment. However, he quoted me $1433.80 to fix the alternator.
This shop tried to take advantage of my desperate situation. After calling around to other shops, I got a quote for LESS THAN HALF of what Steve quoted for labor and part. I bought a new alternator at $200 and had it replaced elsewhere. For other would-be other victims, Westside Transmission & Automotive will rip you off. Call around and check with other garages.

After Taking My 2010 Lexus 450H To Santa Monica Lexus I Was Not Satiated With Their List Of Things That Need Attention. Aside From Te Service Department Not Responding To My Calls I Called The Service Manager And He Said He Would Take Action, The Service Person Had 3 Calls Before She Responded. I Asked For An Explanation And What I Was Told By The Service Adviser Was Not True. After Having Westside Transmission Recommended To Me By A Professional Mechanic I Took It In For Conformation And An Estimate. Steve Put It Up On The Rack And We Looked At The Items They Said Needed Action.
One Was Completely False And Another Was Questionable. Lexus Said The Rear Shocks Needed To Be Replaced Because They Were Leaking. They Were Not, But Did See Some Grease On The Bottom Part. Shocks Use Oil Not Grease. Wondering Why? I Was. WESTSIDE DID A FANTASTIC JOB! THEY WERE VERY PROFESSIONAL.
