The 47RE RFI Noise Filter was designed to eliminate TCC cycling on 1996-present year Dodge trucks. This is a common problem on 1996-2002 Dodge trucks with the 47RE transmission and a diesel engine.

The condition is caused by electrical noise (RFI) in the alternator output and/or throttle position sensor (APPS) circuits.

These noise filters are much easier to install than similar products that are currently available.

This product will eliminate the TCC cycling issue when all other possible remedies have failed.
