722.6 Valve Body 2017, remanufactured and ready to install. Fits the 722.6. Ships fast from the USA.
This remanufactured 722.6 valve body was built around the 2017 Jeep Wrangler JK with the 3.6L Pentastar and the five-speed automatic, the transmission Chrysler calls the W5A580 and most shops call the NAG1. It comes as a complete hydraulic and electrical package: the valve body casting, the conductor plate and the solenoids, already assembled and tested. If your Wrangler flares between gears, bangs into reverse, drops into limp mode in second gear, or keeps setting solenoid and ratio codes after a fluid service, this is the assembly that usually sits behind those complaints.
The NAG1 has no bands in the usual sense; it shifts by applying and releasing clutch packs and brakes, and every one of those apply circuits is fed from this casting. Line pressure from the pump is trimmed by the working-pressure regulator and the modulating-pressure circuit, then the shift solenoids open each shift valve on command from the separate transmission control module. The conductor plate sits on top and carries the wiring that ties the solenoids and the internal speed and temperature sensors back to the round pass-through connector in the case. Because the Wrangler TCM depends on the internal speed sensors to judge every shift, a cracked conductor plate and a leaking valve body bore can look almost identical from the driver's seat, which is why replacing them together as one tested unit removes a lot of guesswork.
Read the codes and freeze-frame data first with a scan tool that can talk to the Chrysler TCM, and check fluid level the correct way at operating temperature. Speed sensor codes with clean wiring point toward the conductor plate; flare and slip with no electrical codes point toward worn valve bores. Our 722.6 valve body symptoms and testing guide walks through the bore wear patterns and vacuum-test method, and the 722.6 speed sensor symptoms guide helps separate a sensor fault from a hydraulic one. If the fluid is black and full of friction material, the clutches are likely done too, and a valve body alone will not fix that.
This listing is matched to the 2017 Jeep Wrangler 3.6L automatic. The rebuilder notes the same assembly design across Chrysler and Dodge NAG1 vehicles from 2006 on, but conductor plates, connector styles and calibrations changed over the years, and Mercedes-Benz badged 722.6 units do not always interchange with Chrysler builds. Match your old unit's casting and conductor plate against the photos, or send us your year and VIN before ordering. Other model years and versions are in the 722.6/722.9 transmission parts collection, including the 722.6 NAG1 valve body assembly for other Jeep and Dodge applications.
If teardown shows burnt clutches, the 722.6 master rebuild kit for the W5A580 covers the frictions, seals and gaskets for a full overhaul.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is matched to the 2017 Wrangler with the 3.6L and the five-speed automatic, and the two-door and Unlimited share that transmission. Manual-transmission Wranglers do not use it. Send your VIN if you want us to confirm before ordering.
Yes. The assembly includes the valve body, the conductor plate and the solenoids, remanufactured and tested together, so you are not reusing an old conductor plate or speed sensors.
Chrysler specifies ATF+4 for the W5A580 in the Wrangler. Do not top it off with a Mercedes 236-series fluid or a generic multi-vehicle ATF unless it carries the ATF+4 approval.
You should reset the transmission adaptive values and let the TCM relearn. Old adaptives were learned around a worn valve body and can cause harsh or soft shifts on the new one until they are cleared.
The TCM defaults to a fixed gear when it sees a solenoid, speed sensor or ratio fault it cannot correct. On the NAG1 that often traces to the conductor plate or worn valve bores, but low fluid and a leaking case connector can cause it too, so check those first.
