545RFE Pump 2006, remanufactured and ready to install. Fits the 545RFE. Ships fast from the USA.
A 2006 five-speed Ram 1500, Durango or Commander that whines with engine speed, has to be revved before it will creep, or sets P0868 for low line pressure once it gets hot may have a worn front pump. This remanufactured 545RFE pump for 2006 is a complete replacement assembly, so you can restore line pressure and converter feed with a tested unit instead of rebuilding a scored pump body yourself.
The pump bolts to the front of the case behind the torque converter, and the converter hub drives its gears at engine speed. It pulls fluid from the pan through the pickup filter and turns it into main line pressure for all six clutches. On the 545RFE the pump also carries a set of valves: the pressure regulator valve, the TCC regulator and TCC switch valves, the TC limit valve and the TCC accumulator. That means a tired pump can cause pressure complaints and lockup complaints at the same time.
Line pressure is closed-loop. The controller commands a pressure control solenoid in the solenoid pack, which acts on the end of the pressure regulator valve, and a pressure sensor on the case reports back what the pump is actually making. When the pump cannot keep up, the gap between desired and actual pressure is the first thing to show it. On a five-speed that tows, the overdrive clutch carries 3rd, 4th and 5th, so lost pressure there burns clutches quickly.
Hook up a scan tool and compare desired and actual line pressure as the truck warms up. A healthy RFE runs within a few psi of target; a worn pump falls behind while the controller drives the solenoid toward maximum pressure. Before you pull the transmission, rule out low fluid, a cracked or rolled pickup filter seal, and a faulty line pressure sensor connector. The 45RFE and 545RFE pump failure guide has known-good pressure readings and the full checklist, and the pressure control solenoid guide covers the solenoid-side faults that can set the same codes.
One 2006-specific trap: Chrysler TSB 21-016-05 covers 2006 Ram, Durango and Commander units that are slow to engage only on the first start after sitting overnight. The cause in that bulletin is converter drainback through cooler return filter 04799662AB, not the pump. If the delay is gone a few seconds after start-up, check that filter first.
This pump is listed for the 2006 545RFE. Pump castings and the lube circuit changed during the RFE run, and some replacement pumps are supplied with a front seal while others are not, so compare your old pump to the listing photos before you order. If you are not sure, send us the year and VIN and we will confirm it. Neighbouring years are listed separately: the 545RFE pump 2007 covers the next model year. The full range of pumps, filters and kits is on the 45RFE and 545RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 45RFE and 545RFE share the same pump design family, and Sonnax lists one remanufactured pump for both. Castings and seal configuration changed over the years, so compare your old pump with the listing or send us the year and VIN before ordering.
Chrysler TSB 21-016-05 covers that complaint on 2006 Ram, Durango and Commander units. The bulletin ties it to converter drainback through cooler return filter 04799662AB, and the fix is a 04799662 filter at a different suffix level. Check that before replacing the pump.
No. The pump sits at the front of the case behind the torque converter, so the transmission must come out. Use that access to replace the front seal, flush the cooler and inspect the converter hub.
Use ATF+4 only. Chrysler lists a service fill of 5.2 L on 4x2 and 6.2 L on 4x4, and roughly 14 to 16 L after an overhaul. Set the final level hot using the procedure for your vehicle.
Known-good data published by GEARS Magazine for a 545RFE shows about 125 psi desired in Park or Neutral at idle and about 60 psi in Drive at a stop, with actual pressure within a few psi of desired.
