8HP45 Clutch Drum 2012-13, used and ready to install. Fits the 8HP45. Ships fast from the USA.
This is the rear end of a 2012-2013 Dodge or Chrysler 845RE: a good used P4 planetary assembly with the D-clutch drum and the output shaft, from a 2WD 8HP45. It carries part number K319586C and includes the 28-tooth sun gear and the ring gear, with the output shaft threaded for the flange nut. If your rear-drive Charger, 300 or other 2WD 845RE has lost 4th through 8th and reverse, or you found a damaged D drum or output shaft on teardown, this assembly replaces those pieces as one matched unit.
The 845RE is Chrysler's build of the ZF 8HP45. It uses four planetary gearsets, two brakes and three clutches, with three elements applied in each gear. Sonnax's apply chart shows clutch D applied in 4th, 5th, 6th, 7th, 8th and reverse, so the D drum is working whenever the vehicle is above third gear or backing up. The fourth planetary set sits at the back of the gear train and drives the output shaft, which is why the D drum, P4 planet and output come out together on this unit. Clutch D is controlled by solenoid EDS-6 in the mechatronic unit.
A pattern of good low gears and bad upper gears and reverse points at clutch D, but confirm the basics first. Check the fluid level with the proper temperature-gated procedure before anything else. Then remember that the 2013 Charger and 300 have a known harsh 2-1 downshift covered by FCA bulletin 21-041-14 that is fixed with a valve body and drive learn, not hard parts. Valve body holding valve bore wear can also burn clutches. Our Charger shift problems guide and ZF8HP common problems guide cover both before you open the case.
This assembly is from a 2WD 8HP45 (845RE) in a 2012-2013 Dodge or Chrysler. FCA's bulletin confirms the 845RE in 2013 Charger (LD) and 300 (LX) models with the 3.6L. All-wheel-drive units use a different output arrangement, so do not order this for an AWD Charger or 300. Match the part number K319586C, the 16 mm pilot that is 32 mm long, and the threaded output shaft against your old part, or send us your year and VIN. It is not for the 2014-up units or the 850RE. If you only need the E-clutch drum, see the new 8HP45 E-clutch drum. The full 8HP lineup is on our ZF 8HP parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the P4 planetary assembly with the D-clutch drum and the output shaft, including the 28-tooth sun gear and the ring gear, from a used 2WD 8HP45. You get the pieces that come out together at the back of the transmission.
No. It comes from a 2WD 845RE. All-wheel-drive versions use a different output setup, so confirm your drivetrain and match part number K319586C.
Clutch D is applied in 4th, 5th, 6th, 7th, 8th and reverse. A failure there usually leaves 1st through 3rd working while the upper gears and reverse slip.
It is sold for 2012-2013 units only. Later years and the second-generation 850RE can differ, so send us your VIN if your vehicle is outside that range.
Use ZF LifeguardFluid 8, which ZF lists with LifeguardFluid 9 as the only approved fluids, set the level at temperature, then run the 8-speed shift adaptation drive learn so the TCM relearns clutch fill.
