🔧545RFE Transmission Repair: P0750 Code Diagnosis and Solution in Spanish | Reparacion

P0750 Low Reverse Solenoid Circuit. 545RFE Transmision Automatica. En este video vemos como se puede diagnosticar y reparar un paquete de solenoides dando este codigo u otros codigos relacionados con este Solenoid Pack. Esta camioneta es una Dodge Ram 1500 del 2010 con un motor de 4.7 Litros. Como vemos y podimos verificar que la transmision estaba en estado de emergencia, "Fail Safe" o "Limp In". Al poner la llave hacia adelante o encender el motor, la computadora hace unas pruebas del estado de todos los componentes para verificar su estado de salud. Es un "Checksum", se le llama. Si la computadora, "TCM" encuentra alguna falla se pone en estado de emergencia. Sean un poco pacientes porque este video lo grabe con mi celular y me fue un poqito deficil hacer todo con una mano y la otra sugetando mi celular. Bueno pues, espero y les guste este video y que sea de gran ayuda. Recuerden que hay que subscribirse, es gratis. Gracias. P0750 LR Solenoid Circuit - 545RFE Transmission Repair *Video Description:* This video documents the diagnostic and repair process for a *P0750 Low Reverse Solenoid Circuit* error in a 545RFE transmission. The presenter troubleshoots a 2010 truck, demonstrating the steps to identify a faulty solenoid and resolve the issue. *Key Steps & Concepts:* *Initial Diagnostics:* The presenter begins by using an OBD2 scanner to read error codes, which reveals the P0750 code and a low TCM power input. *Solenoid Resistance Testing:* The video highlights the importance of testing the solenoid's resistance. The presenter notes that most solenoids should have a resistance between 1.3 and 3 ohms. The faulty low reverse solenoid measured a resistance of 17.1 ohms, far outside the normal range. Other solenoid resistances were measured, such as the low drive at 1.8, the for flush at 1.6, the multi-select at 1.7 and the other solenoids at 1.7. *Identifying the Faulty Solenoid:* Through testing, the presenter confirms the low reverse solenoid is faulty. *Valve Body Removal:* The video shows the removal of the valve body to access the solenoid pack. *Solenoid Pack Disassembly:* The video shows the presenter disassembling the solenoid pack. *Solenoid Replacement:* The presenter replaces the faulty solenoid with a functional one from another valve body. *Reassembly and Testing:* After reassembling, the presenter retests the resistance, finding it within the normal range. *Quick Learn Procedure:* The video shows how to perform a quick learn procedure with the scan tool to ensure the transmission operates correctly with the replaced solenoid. *Live Data:* The video shows live data from the transmission and how the readings change when the transmission is working properly versus when the transmission was in 'limp' mode. *Transmission Operation:* The video shows how the transmission changes gears after the repair, and how it no longer goes into a 'limp' mode. *Troubleshooting Insights:* A faulty solenoid can cause the transmission to enter "limp mode," which restricts it to a single gear. The vehicle's computer disables the solenoids when a fault is detected. The presenter notes the importance of cleaning the connector and using back probes for accurate resistance readings. The presenter confirms the low reverse solenoid is normally open, while there is one normally closed solenoid in the pack. *Visuals:* The video includes clear shots of the valve body, solenoid pack, and electrical connectors. The presenter shows how to use a multimeter to test solenoid resistance. The video shows the scan tool and live data readings. *Target Audience:* DIY mechanics Automotive technicians Individuals interested in transmission repair Owners of vehicles with 545RFE transmissions 545RFE transmission P0750 code Low reverse solenoid Transmission repair Valve body Solenoid pack Automotive diagnostics DIY car repair Transmission limp mode OBD2 scanner #545RFE #P0750 #TransmissionRepair #DIYmechanic #AutoRepair #Transmission #Solenoid #CarTroubleshooting #TransmissionAutomatica
