Auto repair service near South El Monte, CA

The AAMCO External Diagnostic Service is the best transmission checkup available anywhere. Our Centers’ certified technicians can get to the bottom of any transmission problem. With today’s more complex, computer-controlled transmissions, it takes a real expert to be able to diagnose a transmission problem correctly. Getting that diagnosis right can save you a lot of money. The AAMCO External Diagnostic Service is a systematic and comprehensive external evaluation of the overall performance and condition of your transmission. A trained technician will check the level and condition of your transmission fluid: •A low fluid level may indicate a leak •Contaminated fluid has water or particles in the fluid. •Burnt fluid indicates damage from overheating. •Varnished fluid has been overheated repeatedly. •Normal fluid is reddish-brown and translucent, depending on transmission type, with no particular odor. The technician will also check the level and condition of transfer case and differential fluid, where applicable. The technician takes your car on a road test, to experience first-hand any problems you have noticed, and to evaluate your car's performance. Your vehicle will be placed on a lift to inspect the controls under the vehicle for any possible cause of the problem external to the transmission. Finally, the technician will scan the computer for trouble codes*. From these tests, the expert transmission technicians at AAMCO centers can determine what type of problem you might have, and make a recommendation for whatever service is necessary. That comprehensive approach to diagnosing the source of the problem is what sets AAMCO apart.

I would have to say that they are the best at what they do. I took my car wrecked from the accident. They towed my car for free to their shop and started on the paperwork right away. Not only they are honest, they are also reliable. In only 3 weeks I had my car back, in perfect condition. A+ to Pristine Auto. God forbid I have another accident, Pristine is my body shop!

Jesse and his team are top notch! I have been bringing my nissan altima to M&J for the past year and very happy with the work and attention to detail. 5 stars!

Arthur was amazing! He did a wonderful job!

Not happy with this place or the work, took my M3 there one time, and that was all it took. First off I had plenty of work done, header install, carbon intake installed, water pump, coolant hoses, O2 sensors, thermostat, crankshaft seal, and instructed him to repair the oil leaks. Ed says he repaired my oil leaks, yet my car continues to leak oil, he damaged a $400 wheel, which he said, if the shop he knew, could not fix it, he would buy me a new one. When his shop failed to do so, I asked about a new wheel, of course he then said, he had no money to get me a new one, so I paid out of my pocket for a new wheel. I had him install my carbon air box, and he removed my OEM clamps, threw them away and replaced them with some junk hose clamps, stating he did not have the tool to replace the clamps, not sure what that has to do with me. So I took my car to check on the oil leaks and was told and shown by the shop, how the oil pan was not only missing bolts, but some were sheared off from over torquing, I was also missing header and sway bar bolts from his header install, my power steering hose was not secure, causing it to rub on part of the motor, damaging it, there were a few other things he failed to do, now costing me over a $1000 to repair after paying him over $2000 for less than subpar work. Do yourself a favor, and stay away.
