OEM AS68RC Transmission Internal Wiring Harness:
One of the most probable causes of failure to the AS68RC is the transmission internal wiring harness. This problem comes from the copper inside the wires cracking inside the insulator and the cable jacket due to age and use and eventually causing a variety of transmission failures.
Further, the service life of the OEM AS68RC electronics is 120,000 to 150,000 miles (or 10 years), but they often fail sooner due to natural flaws in the original manufacturing quality. Fortunately, the OEM offers an updated replacement that is an absolute part of any rebuild, or high mileage service. This AS68RC Internal Wiring Harness is a true OEM replacement.
Aisin Seiki parts are generally on a large backorder and are difficult to access, but the Aisin experts here at Next Gen keep them in stock!
Note: Each AS68RC takes TWO internal wiring harnesses. Although we offer them separately, it is advised to replace BOTH wiring harnesses at the same time as they often fail together!
