When you choose a transmission specialist, be sure you know exactly what work you are authorizing (i.e. estimate, internal or external diagnosis, or transmission repair).

If asked, the technician should be willing to show you the damaged parts and explain the repair work. Also, ask for a damaged-parts report and a breakdown of the work that was done. If you want to inspect the damaged parts pulled from the transmission, be sure to ask the mechanic when you authorize the work, not after. As with any contract, make sure you understand all aspects of the work. If you give your authorization over the phone, understand exactly what work you are approving. Phone authorization is a binding commitment.

• Is the shop a member of the Better Business Bureau? The Bureau can give you the company's history in dealing with customers.

• Is the company a member of any transmission groups, such as the Automatic Transmission Rebuilder Association (ATRA) or Automatic Service Association (ASA), or is it part of a national franchise that offers training programs to keep technicians up-to-date on new technology.

• Do they participate in continuing education and training programs?

• Is the shop well-equipped with the proper diagnostic tools for your vehicle? One of the easiest things to look for is the hydraulic lifts needed to raise your car.

• Is the shop clean and professional looking? Does it appear to be well-run?

Any warranty is only as good as the company that stands behind it. Your transmission repair should come with a standard written guarantee backing the work.

Some industry organizations offer nationwide warranties. These offer assistance throughout the country from participating member locations and are well-established. Also, some transmission chains may offer a company-backed, chain-wide extended warranty.

You should also understand any restrictions or limitations of the warranty before authorizing work to begin.

The common law of business balance prohibits paying a little and getting a lot...it just can't be done. If you deal with the lowest bidder, it is well to add an amount for the risk you will take. If you do that, you will have enough to pay for something better.
