6HP26 Solenoid Kit 2004, remanufactured and ready to install. Fits the 6HP26. Ships fast from the USA.
A 2004 car with the ZF 6HP26 is now past twenty years of heat cycles, and that age shows up first in the valve body solenoids. If your V8 BMW or Jaguar from that year shifts hard, flares between gears, hesitates engaging Drive or Reverse, or throws a transmission fault and limps in one gear, this remanufactured 6HP26 solenoid kit for 2004 units replaces the worn solenoids with tested pieces and is backed by a 1-year warranty.
A 2004 6HP26 is a first-generation unit, built before ZF revised the family into the Gen 2 6HP28 for later model years. In this generation the valve body carries an MV1 solenoid and a single normally-applied EDS4 solenoid that handles the D and E clutch function, alongside the line pressure solenoid and the other clutch pressure solenoids. The transmission module fires each one with a controlled current, and the solenoid converts that into the oil pressure that applies or releases a clutch. When the internal seals and pintles wear, the solenoid still reads fine on an ohmmeter but leaks pressure, so the clutch it controls fills late or slips, and the module can only compensate so far.
On a car this old, rule out the simple causes first. Check the fluid level at the fill plug and look at the fluid condition, then unplug the transmission connector and look for oil inside it. A BMW service bulletin on these units describes the connector sealing sleeve leaking fluid into the connector, which can damage pins and set faults that look like solenoid failure. If the connector is dry, test the solenoids off the car with both the resistance check and the vacuum test described in our ZF6HP shift solenoid testing guide. For BMW owners, the 5 Series common problems guide covers the other wear items to check on an older 6HP26.
This kit is listed for the 6HP26 in 2004. That year the 6HP26 was used mainly behind V8 engines, for example in the BMW 5, 6 and 7 Series and Jaguar XJ8, while many six-cylinder cars of the same year used the smaller 6HP19. Because a transmission can be swapped or carried across model years, go by the tag on the transmission rather than the car's title year, and check that your old solenoids match the color and connector layout of this set. Faded caps are common on a 2004 unit, so do not rely on color alone. If your tag reads 6HP21, 6HP28 or 6HP34, you have a second-generation unit and need a Gen 2 kit instead. Send your year and VIN if you would like us to confirm. More parts for this family are in our ZF 6HP collection.
If the fluid comes out burnt or the pan holds a lot of friction material, the clutches are already damaged and new solenoids alone will not restore the shift. In that case a full rebuild is the better spend.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Gen 1. The first-generation family is the 6HP19, 6HP26 and 6HP32. Gen 2 units are labeled 6HP21, 6HP28 and 6HP34 and use different solenoids and valve body parts.
Not necessarily. Fluid in the connector usually comes from a leaking connector sealing sleeve. Replace the sleeve and inspect the pins for damage; damaged pins can cause faults even with new solenoids.
The listing carries a 1-year warranty on the remanufactured solenoids.
Clear the stored codes and reset the transmission adaptations with a scan tool, then drive the car through all gears both cold and warm so the module can relearn shift timing.
If the fluid smells burnt, the pan has heavy friction debris, or the car slips under load in several gears, the clutch packs are worn and a rebuild kit is the right repair. Solenoids fix control problems, not worn clutches.
