No one wants to have auto transmission problems. But at some point, whether for transmission maintenance or repairs, you will need to take your vehicle to a local transmission shop in Santa Clara County or your area.

What exactly is a transmission? Auto transmissions move the power from your engine to the wheels on the ground; and in doing so, they match the speed and torque of your engine to that of your wheels.

Vehicle transmissions are sometimes known as gearboxes, because they have a train of toothed gears that pass power to the wheels; automatic transmissions also have fluid couplings called torque converters that pass power from the engine to the gears.

Manual transmissions are less complicated, and therefore may not cause you problems except for average clutch wear due to age of the vehicle, riding the clutch or a poorly-adjusted clutch.


But automatic transmission fluid can overheat and break down over time, causeing damage to moving transmission parts.

The good news is that if you are diligent to take care of your automatic transmission, it will last. Change automatic transmission fluid every 24,000 miles, and have the automatic transmission filter changed as well. Doing this will likely help keep transmission problems away, and your transmission will last a long time, as it was intended to do.

Good auto transmission service in Santa Clara County can be easy to find if you know where to look.

While you're researching transmission repair shops, remember that auto transmission services from prequalified guaranteed Diamond Certified companies may well be your best option.

There are lots of automatic transmission shops in Santa Clara County, including auto transmission shops that serve the major cities of San Jose, Sunnyvale, Santa Clara, Mountain View and Milpitas, as well as those in the smaller towns.

Which one fits best? Start with getting good information. Look at the following ideas for making a good choice on the best auto transmission shop in Santa Clara County for you.

Look for Auto Transmission Specialists in Santa Clara County
Automatic transmission or automatic gearbox mechanics will differ in levels of experience and certification in Santa Clara County, and you of course want good transmission service and should have it.

All auto transmission facilities in California have to be licensed by the Bureau of Automotive Repair. You can check on automatic transmission facilities yourself at that site, and discover any problems recorded for each shop. Remember that this has already been done for Diamond Certified shops. If you don't choose a Diamond Certified location, check the other auto transmission shops in Santa Clara County carefully for yourself.

Automatic transmission or manual transmission mechanics in the larger Santa Clara County cities of Sunnyvale, Mountain View, San Jose, Santa Clara, and Milpitas will sometimes have certifications indicating advanced ability. These may commonly be Automotive Service Excellence (ASE) certifications.

Manufacturer certifications are also available in some cases. The Automatic Transmission Rebuilders Association (ATRA) offers three types of certification based on thorough testing; these include technician, rebuilder, and diagnostician transmission service certifications. These mechanics may handle your transmission problems better than other auto transmission mechanics in Santa Clara County.

Yes, it is. But it isn’t easy to determine unless you have a unbiased, third-party source of information. Diamond Certified auto transmission shops give transmission repair service customers the advantage of a thorough rating system. 

If you want quality from an automatic transmission or manual transmission company in Santa Clara County and the greater Bay Area, you can be confident when choosing Diamond Certified companies. You can read Diamond Certified reports on all certified companies, including verbatim survey responses.

Good quality transmission service is the auto transmission shop's concern. But you have a part too.

Think about simple steps you can take for a better transmission work experience:

  1. Be clear in your conversation with the automatic transmission mechanic. Tell him or her exactly what you expect.
  2. Outline which party will be responsible for calling with updates and service reports.
  3. Before you leave your car, truck or van at the Santa Clara transmission shop you’ve chosen, reiterate your understanding of the agreement. Most problems with local auto repair shops are due to a breakdown in communication, so you can avoid most conflicts by being clear about the expectations you and the auto repair shop have.
  4. Be sure your service writer has a working phone number where they can reach you at all times. Your transmission repairs will go more smoothly when the shop can reach you with updates or necessary authorizations.
  5. Return calls from your auto transmission technician immediately.
  6. Pay for the auto transmission repairs as soon as you pick up your vehicle.

It works for you and for the shop when you make the effort to be a good car transmission service customer. The Santa Clara County auto transmission shop will work well with people who are clear and responsible.

Auto transmission shops in Santa Clara County handle different needs. Here are some common types of auto transmission work:

Gearbox Repair and Replacement Services
Gearbox repair or replacement is sometimes necessary, which means rebuilding a transmission, or remanufacturing and installing a new transmission. Gearbox is another term for transmission: an automatic gearbox is an automatic transmission. An automatic gearbox allows the vehicle to change gears without driver effort; a manual gearbox requires the driver to manually operate a clutch and a gearshift lever to move between gears.

Transmission Rebuilding Services in Santa Clara County
Exactly what is a transmission? Transmissions are sets of gears: they provide the way that a car gets the energy from its racing engine out to its slower-turning or unmoving wheels to perform useful work--to get you started, get you going faster, let you slow down, and make it possible for you to stop the car again while the engine continues to run. Transmissions have moving parts that can fail over time. Transmission work can cost a great deal, because auto transmissions are extremely complicated.


Transmission Fluid
Transmissions, whether automatic transmissions or manual transmissions, need lubrication to reduce wear between moving parts, and this is what transmission fluid is for. But it is important for the car owner to know that transmission fluid is doing more than that: it is preventing heat build-up and transferring power from the car engine to the wheels.

When transmission fluid or transmission oil wears out through shear, it loses the necessary grabbing properties that help clutch plates hang onto each other within the transmission during driving.  This transmission fluid breakdown allows these moving parts to grind against one another and cause lots of transmission-destroying heat. Keep in mind that some types of transmission fluid services replace far less fluid volume than others, and that a full transmission fluid exchange is necessary in order to replace almost all of the worn out fluid with a fresh amount of good transmission fluid.

Automatic Transmission Repairs
The automatic transmission is the kind of power transferring system that does not require the driver to use a clutch and a gearshift to move between gears. A modern automatic transmission has lots of small pieces, but can be thought of as several main parts.  The bell housing is a cone-like case, beside the engine in cars with front-wheel drive, or underneath the car in other cases. Gear types include main and planetary gears. Red transmission fluid lubricates moving parts, and is kept clean by a transmission filter: changing the transmission fluid and the transmission filter every couple years will likely be all your automatic transmission will need for a long and healthy life. A number of sensors and a computer are key parts of the modern automatic transmission, and your car may have a Transmission Control Module which can be thought of as a computer.

Manual Transmission Repairs
Manual transmissions are much less popular in the US than automatic transmissions.  Manual transmissions require more work of the driver, involving pressing a clutch pedal with the left foot and moving a gear shift with the right hand in order to change gears appropriate to vehicle and engine speeds. Manual transmissions are more common than automatic ones in other countries; they cost less, weigh less, use less fuel, and perform better.  The two types of manual transmissions are the unsynchronized type and the constant-mesh gearbox type; the second is the more common type of the two.

Diagnosis of Transmission Problems
Transmission problems are when your manual or automatic transmission won't work, or won't work smoothly as it should. Since transmission problems can be expensive, you will want to avoid this by preventive car transmission service. You should have your transmission fluid checked a couple of times a year, and have any leaks fixed--there are only about six places where leaks happen and these spots should be looked at. Also important is replacing your transmission fluid filter: this may never have been done on your car transmission, and is much cheaper and easier to think about than rebuilding a transmission or having to replace a transmission with a remanufactured transmission.

Transmission Repairs
Transmission repair is cheaper than transmission replacement.  That's why car owners are careful to have their transmission fluid changed, and to make sure they are not losing transmission fluid through leaks. Replacing the transmission filter will fix quite a few transmission problems, and other fairly simple transmission repair steps may be possible at a trustworthy auto transmission shop. Eventually, transmission repair may not be enough, and your transmission will need to be rebuilt or remanufactured. Rebuilding transmissions is costly because of all the parts involved. The important thing is to keep the car transmission from needing to be replaced or rebuilt, at great expense.  That extra auto transmission cost is really unnecessary if you have taken simple preventive steps of transmission service.

Torque Converter Repair and Replacement
The torque converter is a central part of the automatic transmission, and repairing or replacing a torque converter may be necessary in a worn transmission. The torque converter is that part of the automatic transmission that manages the linking between the auto engine and the transmission gears; it is present in an automatic transmission instead of the clutch that a manual transmission has. The torque converter is a connection of hydrodynamic fluid for transferring power from the car engine to the wheels.

Transmission Fluid Change
Transmission fluid change is important for extending the life of something which is extremely important and very expensive to replace: your car transmission. Flushing and changing automatic transmission fluid takes out small pieces of clutch material and metal that wear down your transmission, gives your transmission better lubrication, gives your clutches better grabbing ability and reduces harmful transmission overheating. A typical approach to transmission service may be to have the transmission technician only take off the transmission fluid pan, put in a new transmission filter, put the pan back on, and replace the rather small amount of transmission fluid that was drained away.

Even though that type of transmission fluid service is clearly helpful, it may only replace less than half of the transmission fluid, leaving lots of old fluid in your transmission. That worn transmission fluid lets parts slip and allows damaging heat to happen. A full transmission fluid exchange is an important preventive transmission service step, and something you should consider at a reliable auto transmission shop. By getting a transmission fluid exchange service, you can replace nearly all of the old, used transmission oil.

Auto Transmission Services
Any machine, for example a car, has a power source and a way of putting that power to useful purpose.  For your car, the source of power is the internal combustion engine, and the means of transferring that power to the wheels is the auto transmission.  The car transmission is either an automatic transmission where the gear shifting is done for the driver by the transmission itself, or a manual transmission with a clutch pedal and gearshift for the driver to use to change gears.

The term transmission may sometimes be used to mean only the gears and gear trains of the gearbox, which change speed and torque. Auto engines need to run at relatively high speeds which are not workable for things like getting going, going slowly, changing speeds over a broad range, and coming to a stop; it is the car transmission that makes these practical uses of the car possible. The transmission, connected to the engine by the crankshaft, turns the higher speed of the engine into the lower speed and higher torque of the wheels.

Having your transmission filter and automatic transmission fluid changed every 24,000 miles is an excellent idea. Unfortunately, most car owners ignore this recommendation.  Doing this one thing would probably be enough to keep your transmission healthy for a long life. Food for thought.

Q: What are some common signs of transmission problems?
One common sign of transmission problems is a low level of automatic transmission fluid, or evidence that transmission fluid, which is generally red but could be confused with power steering fluid, has been leaking from your automatic transmission. Unusual noises coming from the car transmission, shuddering and hard work at shifting, a slipping of the transmission (where the engine speeds up but the car doesn't move forward or backward at the pace it normally would), or failure of the car to move would all be possible indications of transmission problems.

Q: Is it okay to drive when my car transmission has been leaking automatic transmission fluid?
Even a small decrease of automatic transmission fluid volume will change the way the transmission works. You should seriously consider seeing a reliable auto transmission shop in San Mateo County right away if not sooner.

Q: What does an annual transmission check cost?
The answer will vary, but you may find that such transmission services as a road test and certain automatic transmission checks will be done at no charge.

Q: What is automatic transmission fluid exchange?
Transmission fluid exchange goes beyond the basic automatic transmission fluid service, which may replace about half of your car transmission fluid.  Transmission fluid exchange replaces nearly all of your used transmission fluid with fresh fluid for improved performance.

Q: What are some common automatic transmission services?
The auto transmission shop will check the level of your automatic transmission fluid, and determine the condition of the fluid. The shop might road test your automatic transmission with both a stationary test and a driving test, looking for evidence of slipping, early or late shifting, irregular shifting, or hard or soft shifting. A pan examination looks for damage inside the automatic transmission.

Q: How long will it take to repair my transmission?
The amount of time it takes to fix your automatic transmission or manual transmission will vary of course, based on the type of transmission problem you have. Routine exams will allow you to get the car back the same day. Many transmission problems require only minor repairs, and these can also be done within the day. Rebuilt transmissions will take longer.

Q: What sort of warranties come with a rebuilt or replaced transmission?
Various warranties will probably be available, ranging perhaps from 6 months to 5 years. A lifetime warranty may be available in some cases.

Q: What does it mean to have my automatic transmission scanned?
Scanning hooks a computer up to the one in your car to look for trouble codes and check sensors, and may find problems with the electronic part of your transmission.
