Although transmission repair is not the end of the world, it might seem close to it at the time. Most of the time this part of your car will need more than just repairs. If there seems to be a transmission repair needed you might end up needing to have it replaced with a new one or a rebuilt one. If you start seeing signs of a problem here then you would be wise to begin your search for a good mechanic to check your transmission. Repair work will most likely be much cheaper than a replacement, so if you catch a problem before the whole part goes you may save some cash.
A mechanic that works with transmissions will charge varying amounts because of the labor that can go into working on them. You might be wise to check with your regular mechanic to see if they have suggestions. Also, you might ask them for some specific warning signs of a possible problem. If you know what to look for it could save you the money of having to go to a few mechanics before one can help you.
Once transmissions are gone they will not have much power. This is something that should be kept in mind. Knowing this, you might want to have someone help you transport your vehicle if the problem does seem serious, or you might want to call and see if the transmission repair mechanic will tow it for you.
As you look for a mechanic, definitely talk to your regular mechanic, friends, and go on the internet to look for reviews of various companies that do this type of work. If you go to a chain, you may have a more standard process and prices. If you shop around you may end up finding someone to do it cheaper, but the guarantee of a good job is not always there.
Before hiring a mechanic, if you have time, perhaps go and visit the shop and meet them. What you should look for is someone who is cordial, takes the time to explain things well, and offers amenities for patrons who are waiting. The waiting area should be clean, as well as the restroom. Some snacks and even some books for kids is an added benefit. It really will depend on what you are looking for in these last areas. Customer service is important, but ultimately their ability to fix your car is the highest priority.
