Warranties
Any warranty is only as good as the company that stands behind it. Your transmission repair should come with a standard 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 offer a company-backed, chain-wide extended warranty.
Some warranty programs may be administered by outside warranty and insurance companies. However, check with your transmission specialist to see if the repair facility will honor the warranty should the administering company go out of business.
You should also understand any restrictions or limitations of the warranty before authorizing work to begin.
