RE5R05A Tcc Solenoid 2002, new and ready to install. Fits the RE5R05A. Ships fast from the USA.
This is the Bosch-boxed 0 260 130 031 solenoid for the RE5R05A, and the "2002" in its name marks where the story starts: the RE5R05A debuted in the 2002 Infiniti Q45, and this solenoid style has been on the valve body since. Owners of a Nissan Titan, Armada, Pathfinder, Xterra, Frontier or Infiniti QX56 usually find it while chasing a highway shudder, an engine that will not drop RPM in fifth, or a scan tool that keeps reporting a lockup or line pressure circuit.
On this transmission the torque converter clutch is not switched on and off. The TCM pulses the TCC solenoid so lockup pressure rises in a controlled ramp, letting the converter clutch slip a little during the apply and then hold solid at cruise. That is what keeps engine speed low on the highway. One useful detail: the line pressure (EPC) solenoid, the TCC solenoid and the front brake solenoid in the RE5R05A all use this same silver-capped, normally venting Bosch body. One part number covers three positions, which is why it is often listed as an EPC, TCC and front brake solenoid. Sonnax also notes that pilot valve A feeds both the line pressure solenoid and the TCC solenoid, so those two circuits share a supply.
Shudder is not always the solenoid. Transmission Digest documented an RE5R05A that still shuddered after a radiator cooler failure had been repaired, because the contaminated fluid had already damaged the converter clutch lining. Check the fluid color and smell, check the code history, and measure the solenoid resistance against a known-good one before buying. A stuck pilot valve can also starve both the TCC and line pressure circuits at once. Our RE5R05A service guide covers the pan inspection and solenoid checks. If the module itself is suspect after the wiring checks out, compare against a replacement RE5R05A TCM.
Fits the RE5R05A five-speed from 2002 on, in the line pressure, TCC and front brake positions, as Bosch 0 260 130 031. Applications include the Infiniti Q45 where the unit started, the QX56 and the Nissan Titan, Armada, Frontier, Pathfinder and Xterra. It does not fit the direct clutch, input clutch, high and low/reverse or low coast positions, which use different solenoid bodies. Also be aware that Sonnax lists three RE5R05A valve body design levels; the solenoid is shared, but the valve bodies are not interchangeable. Match the silver cap and connector on your old part, or send us your year and VIN. See every part for this unit on the RE5R05A collection page. Our other listing of the same Bosch number is the RE5R05A TCC solenoid.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. 2002 is the year the RE5R05A started production in the Infiniti Q45. This Bosch 0 260 130 031 solenoid fits 2002 and later RE5R05A units.
Both. The RE5R05A uses this same Bosch body in the line pressure (EPC), TCC and front brake positions. Install it in whichever of those three bores failed.
Only if the solenoid caused it. If the fluid was contaminated by a failed radiator cooler, the converter clutch can be damaged and keep shuddering.
Lockup codes such as P0740, P0741 and P0744 point to the TCC position. Line pressure or front brake circuit codes point to the other two bores this part fits.
At minimum the filter, pan gasket and fresh Matic S ATF. If more than one solenoid circuit is faulting, replace the full solenoid set.
