5R55E Shift Kit 1995, remanufactured and ready to install. Fits the 5R55E. Ships fast from the USA.
Most people who type in 5R55E shift kit own a 4.0L Ford Ranger or Mazda B4000 that has started shifting soft, flaring from third to fourth, or throwing a converter lockup code. Before you order, know what this listing is: not a box of springs and valves, but a remanufactured set of the OEM electrical solenoids that bolt to the 5R55E valve body, the six pieces shown in the photo. Each was inspected for proper operation, and the set is catalogued for the Ford and Mazda 4R44E, 4R55E, 5R44E and 5R55E family from the 1995 model year on. On a five-speed with clean fluid, tired solenoids cause many of the complaints a shift kit gets blamed for. If you do want the hydraulic kit, we sell the TransGo 5R55E shift kit on its own page.
The 5R55E grew out of the A4LD by way of the 4R55E. The Ranger Station notes that it is mechanically close to the four-speed 4R55E and gets its fifth gear through software, which means the PCM, acting through these solenoids, decides every gear. The shift solenoids switch on and off to stroke the shift valves. The electronic pressure control (EPC) solenoid takes varying current and turns it into line pressure through the boost valve, so it sets how hard every band and clutch is clamped. The converter clutch solenoid commands lockup at cruise. Because the five-speed relies on timing one element releasing as another applies, a solenoid that responds slowly shows up as flare or a soft overlap far sooner than it would in an older four-speed.
Pull the pan first. Burnt fluid and friction material on the magnet mean the bands or clutches have already failed, and a solenoid set will not fix that truck. With clean fluid, read codes, then put a gauge on line pressure: pressure that stays flat while the PCM raises EPC command points to the EPC solenoid or a worn boost valve bore. Sonnax publishes a vacuum test guide for this family that finds bore leaks before you spend money. Our 5R55 harsh or delayed shifts walkthrough covers the test order, and the stall test and lockup diagnosis guide separates a converter fault from a solenoid fault.
The Ranger Station lists the 5R55E behind the 4.0L V6 in 1998-2011 Rangers, with the swap from the 4R55E happening during 1997, and it went into the matching Mazda B4000. The listing title says 1995 because the set is catalogued for the whole family from the year the 4R44E and 4R55E launched; the 5R55E itself did not exist yet in 1995. Solenoids and connectors changed over the run, so send us your VIN before ordering, or match the solenoids on your valve body to the photo. More parts for this family are on our 5R55 parts page.

No. It is a remanufactured set of OEM electrical solenoids for the valve body. Our separate TransGo 5R55E shift kit listing is the hydraulic spring and valve kit.
The set is catalogued for the 4R44E, 4R55E, 5R44E and 5R55E family from 1995 on, and the 5R55E is the five-speed behind the 4.0L in 1998-2011 Rangers and the Mazda B4000. Send us your VIN so we can confirm the correct set before it ships.
The set is listed for the whole family starting with the 1995 model year, when the 4R44E and 4R55E replaced the A4LD. The 5R55E itself arrived during the 1997 model year.
Mercon V. Sonnax notes that early factory Mercon V shortened solenoid life in these units, so remove as much old fluid as practical before refilling.
Clear codes and let the PCM relearn by driving through all gears with the fluid at operating temperature. Shift feel usually settles over the first several drives.
Only if the slip is caused by low or erratic pressure from the solenoids. If the fluid is burnt and there is friction material in the pan, the bands or clutches are worn and the unit needs a rebuild.
