Within the 125,000 to 185,000 miles range, nearly 60% or more of the automatic transmissions will fail. The most common failures are loss of reversal, or lack of a third or fourth gear, sometimes falling from first to second, or transmission will fail completely. Most gearboxes used in Atransmissions have a high mileage and need to be replaced when you buy it. Rebuilding the transmission will give you peace of mind that your newly purchased transmission will be cleaned, tested, and rebuilt to an improvement in factory specifications, a transmission used at about another 1/3 the price. Their transfers in Atransmissions are run through an assembly line process, using strict standard guidelines to ensure quality. Each transmission is thoroughly cleaned, prepared, and quality checked to ensure that it is free from dirt and debris, and the transmission fluid is cherry red.
