Transmission Line Pressure Sensor Connector Pigtail for 45RFE/545RFE/65RFE/66RFE/68RFE, Compatible with Ram 2500/3500 (6.7L Cummins), Ram 1500, Dakota, Durango, Jeep Grand Cherokee, Commander

Wire Harness Length:16CM

• Wire Harness Length:30CM What it is / Specs — 3-pin harness-side connector pigtail for the Transmission Line Pressure Sensor (a.k.a. RFE pressure transducer). Wire length ~30 cm (≈11.8"), pre-crimped leads, includes heat-shrink & butt splices. Cure cracked/corroded plugs that cause pressure DTCs on Chrysler RFE transmissions.
• Fitment – 68RFE (HD diesel) — Ram 2500/3500 equipped with the 6.7 L Cummins using the 68RFE automatic, approx. 2007.5-up (line-pressure transducer family). This pigtail mates the harness to that sensor on 68RFE units.
• Fitment – 545RFE (V8 gas SUVs/trucks) — Jeep Grand Cherokee (≈2001-2010), Jeep Commander (2006-2010), Dodge Durango (≈2004-2009), Dodge Ram 1500 (≈2003-2011), Dodge Dakota (≈2003-2011), Chrysler Aspen (2007-2009), plus Jeep Liberty CRD (2005-2006) that uses the 545RFE. All these models place a pressure transducer on the RFE valve body/solenoid pack that uses this 3-pin connector.
• Fitment – early 45RFE (V8) — 1999-2000 Jeep Grand Cherokee (4.7), 2000-2002 Dodge Dakota (4.7), 2000-2002 Dodge Durango (4.7), 2002 Ram 1500 (3.7/4.7). These applications are the 45RFE/5-45RFE predecessors that use the same style 3-pin pressure-transducer connector.
• Also fits later RFE family — Connector is specified for 45RFE / 545RFE / 65RFE / 66RFE / 68RFE as an RFE-family transducer connector repair (industry reference RFE-RC1). For later gas-engine Rams this covers 2012-2013 65RFE (Ram 1500) and ~2013-2018 66RFE (Ram 2500/3500 5.7/6.4 HEMI).
• OE & Interchange (for the sensor the pigtail plugs into) — Primary OE: 4799758AF (aka 04799758AF). Supersessions commonly cataloged: 04799758AB / 04799758AC / 04799758AD / 05016222AA. (Note: these are the line-pressure sensor numbers, not the pigtail’s.)
• Industry repair reference (connector side) — Common catalog reference for this RFE transducer connector pigtail is RFE-RC1 (RFE family, 45/545/65/66/68RFE). Use this as an aftermarket cross only; the OE typically supplies VIN-specific connector repair kits rather than one universal connector OE.
• Component location / function — The line pressure sensor (transducer) monitors hydraulic line pressure for the TCM; it’s mounted on the valve body/solenoid pack area depending on year/variant in the RFE family. This 3-pin pigtail is the harness-side plug for that sensor.
• Install tips — De-pin and splice one wire at a time to maintain circuit order; stagger splices; seal with heat-shrink. After repair, clear DTCs and verify pressure PID and shift feel. (RFE units with damaged connectors often log “pressure control out of range / erratic line pressure.”)
• Not for — 2-pin input/output speed sensors or A/C pressure sensors unless you’ve visually matched the keying and pin-count to your vehicle; this listing is for the RFE line-pressure transducer 3-pin connector. (Speed-sensor pigtails commonly use different 2-pin shells.)
