We can usually rebuild your transmission for less than exchanging it. All of our new and rebuilt transmissions carry a 12mo/12,000 mile warranty. Send us your transmission, transfer case, or differential & we'll disassemble, clean & inspect it. Next, we'll contact you with an exact price to repair the unit, including all parts and labor. After you approve the work, we can usually complete the repairs in 1-2 business days.
Remember, we can ship anywhere you need us to - usually on the same day! We accept: Mastercard, Visa, & Discover. We ship via UPS, motor freight, U.S. Postal Service, overnight, 2 day, 3 day, or regular freight, depending on your needs. International Shipping is quoted to nearest airport. Customer is responsible for all duties, etc. that may be imposed in your country. |
