The 5R55E transmission produced by Ford Motor Company, was introduced in the 1997 model year, and is thefirst 5 speed automatic found in domestic vehicles. It is currently found in the 1997 Aerostar Van, 1997-2001

Ranger Trucks, both 2WD and 4WD, and 1997-2001 Explorer vehicles, equipped with the 4.0L engine. Thisunit is very similar to the 4R44E, but has different computer strategy that energizes the overdrive band in firstgear, to create the added gear ratio. Refer to the application chart found on Page 7 for the new computerstrategy. Many of the parts between the 4R44E and 5R55E units may look the same, but are not allinterchangeable. Be very careful when selecting replacement parts, if it becomes necessary.

DIGITAL TRANSMISSION RANGE (DTR) SENSOR DIAGNOSIS

1. TR_V is the voltage at PCM connector 175B, pin 9 (TR3A Cir cuit) to Signal Return .2. TR_D: 1 = Open DTR Switch 0 = Closed DTR Switch

4. Breakout Box readings are taken f rom PCM signal pins for TR1, TR2, TR3A, TR4 to Signal Return . Voltages for TR1, TR2, TR4: 0 = 0.0 Vol ts (Shorted to Ground) 1 = 9.0 to 14.0 Vol ts (Open Cir cui t) Voltages for TR3A: 0 = 0.0 Volts (Cir cuit Shorted to Ground)

1 = 1.3 to 5.0 Vol ts (Open Cir cui t) 1.8 to 5.0 Volts is an invalid reading and is usually an open in wir es or bad resistor in DTR sensor.
