8HP70 Pressure Control Solenoid 2013-2018, new and ready to install. Fits the 8HP70. Ships fast from the USA.
Read this before you order: despite the solenoid name on this listing, the part that ships is a PPE 228058600 replacement transmission filter, new, for the ZF 8HP70 eight-speed. It is the service filter for PPE's heavy-duty cast aluminum transmission pan, the upgrade many Ram 1500 EcoDiesel and Hemi owners bolt on for extra fluid capacity and a drain plug. If your truck already wears a PPE pan and it is time for a fluid change, this is the filter you want. If you still run the factory plastic pan, or you are chasing a harsh shift or a P0748 code, this filter is not the fix, and we explain below what to look at instead.
On a stock 8HP70 the filter is molded into the plastic pan, so every service means buying a whole pan. PPE's aluminum pan separates the two: the pan stays on the truck and only the filter element is replaced. Fluid is drawn from the sump through this filter before it reaches the pump, which feeds line pressure to the mechatronic unit and its solenoids. PPE states the element captures contaminants 30 to 40 microns smaller than the stock filter. Cleaner fluid matters in this transmission because the clutch and line pressure regulators have small inlet screens and tight valve bores, and wear debris circulating through them is what turns a healthy unit into one with shift complaints.
Drain the fluid and look at your pan. A factory 8HP70 pan is black plastic with the filter built in; a PPE pan is cast aluminum with a removable filter. PPE lists this filter for its pan part numbers 228053000 and 228153000 only. If your shift quality has changed, diagnose that first: our ZF8HP common problems guide covers the leaking connector sleeve and adaptation faults, and the EPC solenoid diagnosis guide covers the actual pressure control solenoid, including its resistance test.
The listing names the 8HP70 in 2013-2018 Ram 1500 EcoDiesel trucks. Be aware that the EcoDiesel did not arrive until the 2014 model year, and PPE itself lists the filter for 2014-and-later 3.0L EcoDiesel and 5.7L Ram 1500 trucks. In practice fitment follows the pan, not the vehicle: it fits only behind a PPE 228053000 or 228153000 pan. It is not a direct replacement for the stock filter. If you are not sure which pan your truck has, send us a photo or your year and VIN. You can buy the matching 8HP70 cast aluminum pan 228053000 here, and every eight-speed part we carry is on the ZF 8HP collection page.
Park level, drain the fluid through the pan drain plug and remove the pan. Pull the old filter straight down out of the valve body suction port, check that its seal did not stay behind in the bore, and press the new filter in fully. Clean the pan and magnet, inspect the gasket, and reinstall the pan with even torque on the bolts. Refill only with ZF LifeguardFluid 8; ZF permits only LifeguardFluid 8 or 9 in these units. Our 7-liter Lifeguard 8 service fill covers a typical pan drop. Fill through the side fill plug with the engine running and set the level at the specified fluid temperature; an in-car service takes much less than the roughly 9 liters Sonnax lists for a dry, overhauled unit. If the truck still has the factory pan, the simpler service is a complete 8HP70 fluid and filter service kit with a new plastic pan.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the listing title, this is a PPE 228058600 replacement transmission filter for PPE aluminum 8HP70 pans. If you need the line pressure solenoid, look at our 8HP70 solenoid kits instead.
No. On the stock 8HP70 the filter is built into the plastic pan. PPE states this filter is for its 228053000 and 228153000 pans only and is not a direct replacement for the stock filter.
Only if the truck has a PPE 228053000 or 228153000 pan installed. The EcoDiesel began in 2014, and PPE lists the filter for 2014-and-later EcoDiesel and 5.7L trucks, so send us your VIN if you are unsure.
ZF LifeguardFluid 8. ZF's data sheet allows only LifeguardFluid 8 or 9 in these transmissions.
Replace it at every fluid change. The point of the PPE pan is that you can change the filter without replacing the pan, so there is no reason to reuse a dirty element.
