5HP19 Solenoid Kit 2001-2004, new and ready to install. Fits the 5HP19. Ships fast from the USA.
The 2001-2004 years are the M54 era of the ZF 5HP19: the six-cylinder E46 325i, 325Ci, 330i and 330Ci, the E39 525i and 530i, and the early Z4 2.5i and 3.0i. If one of those cars now bangs into Drive, flares on the 2-3 shift, or drops into transmission failsafe, the solenoid group on the valve body is one of the first things a transmission shop checks. This new kit is listed for 2001-2004, and the photo shows seven solenoids clipped to an internal harness that ends in the round case connector, along with a sensor lead, so you can renew the whole electrical side in one pan-off job.
The 5HP19 has no throttle valve cable and no governor. The transmission control unit reads turbine and output speed, engine load and fluid temperature, then drives the solenoids to carry out every shift. The on/off solenoids stroke the shift valves that select each gear. The proportional EDS regulators set pressure, and EDS 1 is the one that matters most: it controls modulating pressure, which feeds both line pressure and the accumulator back pressure that softens each clutch apply. ZF's parts catalog splits these BMW units into two transmission codes, TT (ZF 1060 000 009) behind the 2.5-liter M54 and TU (ZF 1060 000 010) behind the 3.0-liter, but both are the same 5HP19 family and share this control layout.
ATSG ties the firm-engagement and harsh-coast-down pattern on 5HP19 units to a mechanically sticking EDS 1 that raises modulating pressure, and notes it is more common on 2003 and newer transmissions. On a car that has never had the solenoids replaced, the other regulators have the same mileage, which is the argument for a full set.
Read the transmission faults with a BMW-capable scan tool rather than a generic code reader, since many 5HP19 faults never show up as a generic P-code. Check the fluid level hot on a level surface; a leaking connector sleeve or pan gasket can drop the level enough to cause flare on its own. With the pan off, our bench testing guide covers resistance and flow checks for each solenoid, and if you cannot get to a dealer-level tool, the guide to testing solenoids without a factory scan tool shows what you can still prove at home. Heavy clutch debris in the pan means the problem has moved past solenoids.
This listing covers the 5HP19 from 2001 to 2004. By ZF's catalog that includes the E46 325i, 325Ci, 330i and 330Ci, the E39 525i and 530i, and the Z4 2.5i and 3.0i. Earlier 323i and 328i cars from 2000 and before used an M52 version of the transmission, and Audi and VW models use the 5HP19FL and FLA with their own harness layouts, so do not assume a match from the year alone. Compare the solenoid styles, connector shapes and harness routing in the photo to what is on your valve body, or send your year and VIN and we will check it for you before it ships. The ZF 5HP19 7-piece solenoid kit is an alternative if you only need the solenoids.
Raise the car level, drain the fluid, and remove the pan and filter. Note the routing of the harness before unclipping it, then remove the solenoids one position at a time so nothing ends up in the wrong bore. Fit new O-rings where used, and check that the modulating pressure valve near EDS 1 slides freely in its bore before the new regulator goes in. Inspect the seal where the harness passes through the case while it is out, and replace it if it shows any seepage. If you are adding firmer shift calibration at the same time, the 5HP19 shift kit for 2001-2006 goes in during the same service. Install a new filter and pan gasket, refill with the fluid your transmission's ZF plate calls for, and set the level at operating temperature. Finish by clearing faults and resetting the transmission adaptations, as explained in our adaptive relearn guide. If the shift slip continues after the solenoids are in, the clutches are worn and a ZF 5HP19 master rebuild kit is the next step.

The 2001-2004 E46 325i used the ZF 5HP19 (transmission code TT), which is the unit this kit is listed for. Compare the solenoids and harness in the photo to yours, or send your VIN so we can confirm before it ships.
The 330i and 530i use the TU-coded 5HP19 and the 325i and 525i use the TT code. They are the same transmission family with different internal calibration and converter, and both use the same style of valve-body solenoid group.
Often, yes. ATSG links a hot, firm engagement plus harsh coast-downshifts on the 5HP19 to a sticking EDS 1 pressure regulator. Confirm the fluid level and read the transmission faults first.
The photo shows the solenoids on an internal harness with the round case connector. Check the photo against your valve body, and if your old harness is cracked, a separate 5HP19 internal wiring harness is also available.
Fill and check the level hot, clear the stored faults, and reset the transmission adaptations with a capable scan tool. Then drive normally so the control unit can relearn shift timing on the new parts.
