The liability of SWT is solely and exclusively limited to supplying a replacement transmission if available or refunding purchase price. SWT does not assume and has no liability for labor costs or replacement of oil or anti-freeze, damage to other transmission parts or components towing charges, telephone calls, freight, lost profits, lost time, substitute transportation or replacement vehicle or any other consequential damages.

Southwest Transmissions sells used automobile engines and transmissions, not used automobiles.

State and federal laws regulate odometer mileage for most used automobiles, but odometer mileage determinations for used transmissions and transmission parts are not practically possible, and are not subject to known state and federal laws. Determination of mileage use for used engines or transmissions cannot be done with certainty because these engines and transmissions are routinely sold and transferred separate and apart from the original vehicle in which they were installed. Therefore all representations of mileage are estimates based upon information and belief.

Southwest Transmissions does, however, offer extensive engine and transmission part warranties regardless of mileage, relying upon Southwest Transmissions expertise evaluation of its products.

We do NOT accept anything Freight Collect.
