The best-known issues with the Chrysler 545RFE transmission are definitely problems with the transmission pump. Many drivers with pump issues have noticed that their vehicles either creep forward or won't move at all. Sensor,Transmission Oil Pressure, Dodge, Ram, Jeep, Truck, 45RFE, 545RFE. The issue has been investigated thoroughly, and the culprit is the pump spacer plate. Free Shipping - Mopar Replacement Transmission Oil Pressure Sensors with. More specifically, the pump spacer plate had two screws that tended to come loose or fall out. When this happened, the pressure in the main line fell significantly. This video explains how to replace the Transmission Fluid Pressure Sensor on Chrysler 45RFE and 545RFE Transmissions found. This issue, like many of the issues with this vehicle, is difficult to fix on your own. If you have the skills and the equipment, you can replace the transmission with either a newer pump or a remanufactured pump. The newer transmission pumps were redesigned to deal with this issue by simply removing the screws and casting the holes shut. Most remanufactured 545RFE pumps will be modified to deal with this issue, as it is very well-known. Harsh or Delayed Shifting IssuesĪnother common problem with the 545RFE transmission is harsh or delayed shifting, especially when shifting from third to fourth gear and from fourth gear to fifth gear. If your vehicle hesitates when making these shifts and then jerks into gear, your transmission likely has a problem with its valve body. These harsh shifts are usually caused by a worn checkball that allows fluid to get by and engage the underdrive clutch. You must replace the #2 checkball to solve this issue. The UD clutch is used in forward gears, but not for Reverse. You have either a mechanical or hydraulic issue. This requires you to take the transmission apart and locate the checkball in the valve body. If it doesn't enter a 'limp-in' mode, then the problem isn't electrical. Once you have located the problem checkball, you can replace it fairly easily. The hard part of this job is taking apart and reassembling the transmission. The 545RFE transmission is electronically controlled, so it doesn't have any transmission bands. It instead relies on a solenoid switch pack to send the fluid to the right clutch pack. If your transmission is old and has a lot of miles on it, the solenoid pack may go bad. If this happens, your vehicle may go into a safety mode that limits the vehicle to very slow speeds. It may even fail to engage gears entirely. If this happens, you have to replace the solenoid packs. Thankfully, it is relatively simple to replace a bad solenoid pack. All you need to do is remove the fluid container, pop out the old solenoid, and pop in the new solenoid. Be sure to match the color-coded wires on your new solenoid to the wires on the old solenoid. Early Designs of this part were brass, and frequently leaked. This is the most up to date Oem Brand New Product, and not an offshore item ( Avoid Those ). This Fits All The Below Transmission Applications : 45RFE / 45-RFE. The 545RFE transmission occasionally has problems with the pressure sensor, which is mounted on the side of the transmission. Sometimes Called A Line Pressure Sensor or Case Sensor. If it is just starting to go bad, you may notice that your transmission takes too long to get into gear. If the pressure sensor has completely gone bad, the transmission may stall or overheat. What might work to resolve a P0841 code in a Dodge might not work for a Ford. It’s a generic powertrain code that applies to most modern vehicles that have OBD-II diagnostics. Place where the industries best transmission rebuilders work together to help solve the most complex automatic transmission problems.Replacing a bad pressure sensor is relatively easy on the 545RFE transmission, as the pressure sensors are located in an easily accessible location on the side of the transmission. Diagnostic trouble code (DTC) P0841 stands for Transmission Fluid Pressure Sensor / Switch ‘A’ Circuit Range Performance.
