Engine repair service near Charter Oak, 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.

They are not BBB accredited! They do not abide by their warranties/ contracts! They are sketchy! I was recommended to P&G from sals auto mechanic in fontana, I have a toyota celica Gt 01 that had sucked up water into the intake. I needed a new engine. Sal had told me that this was the place to go. Alex, the owner had quoted me a fair price to install a new 1zz motor (the same kind my car comes with originally) he also said he could switch the position of my intake so that it wouldn't suck up water again.(He didn't) The job was to take 7 days and cost me $2200 with a 1 year or 12,000 mile warranty on all parts and labor. However, upon initial payment of $1100 and 12 days later. I called Alex and he said I needed a new air control valve because the car wouldn't idle right, he also said he needed to install a new "knock sensor", something I've never heard of before. It would cost me an additional $250 and another day of work, I said okay. I just wanted my car fixed. Finally after about 12 days and after I paid the $1450 I got my car back, I understand that cars with new engines have a "break in" period of 3 or 4 months for it be in top condition; so I made sure to drive with caution and made sure not to accelerate over 3000 rpms in between gears. After 1 month, my check engine light came on and my temp was spiking. I took it back to Alex and he said I needed a new temp coolant sensor. I paid $125 for the part and he installed the part. The problem did not go away. Not even a day later the light came back on and he said it was suppose to be a different sensor. He told me he charge me for this new mystery sensor, but after he installed it the problem seemed to be gone. I drove my car for 2 months before I got an oil leak. I took it back and Alex told me it would cost $600 for a new head gasket and seals, he also said that he would not cover it under the warranty because it was because of overheating due to the temperature coolant sensor, the same one that he installed 2 months before! Be warned! This company is not BBB accredited! They are sketchy! And they do not abide by their warranties/ contracts!
