Some transmission air lines may be crimped improperly

Dana Corp has announced that some heavy-duty trucks with Eaton Fuller transmissions may be equipped with an air line that is not properly crimped at the swivel fitting. It advises owners to inspect the fitting to ensure a proper crimp is in place. The transmissions are designated RT/RTO/RTLO with serial number prefix K, and they were built between March 1, 2002, and April 15, 2002.

The air hoses in question are plumbed from the A-5000 slave valve mounted on the driver side of the transmission to the air filter regulator and range cylinder on the rear of the transmission. The hose may disconnect while under pressure, causing a secondary air system leak.

On trucks within the affected population, Eaton Fuller will allow 0.5 hours labor for inspection and replacement of the suspect hoses when necessary. Warranty claims may be filed through standard OEM warranty procedures. For assistance, phone 800-826-4357.
