Aluminum replacement pan for the ZF 8HP70/8HP75 (850RE) in Ram 1500, Charger, Challenger, 300 and Grand Cherokee. Stops plastic-pan leaks.
If the plastic transmission pan on your Ram 1500, Charger, Challenger, Chrysler 300, Durango or Grand Cherokee is weeping at the flange, or it cracked after a rock or a jack pad found it, this aluminum pan is a permanent replacement. It fits the ZF 8HP70 and 8HP75 eight-speed, the second of which Chrysler builds as the 850RE, and it replaces the factory plastic pan sold under Mopar 68225344AA, 52854834AA, 52854834AB, 68233701AA, 68233701AB and 68233701AC and Dorman 265-850. The pan ships with a gasket and mounting bolts and weighs 7.3 lb.
The pan is the fluid reservoir under the valve body and the sealed bottom of the case. On the factory plastic version, ZF molds the filter into the pan, so the original part is pan and filter in one. ZF's own service information shows that aluminum 8HP pans work differently: the filter is a separate part that mounts to the underside of the valve body. That matters for this job. When you swap from the plastic pan to this aluminum one, the old filter leaves with the old pan, and a separate filter has to go in before the new pan goes on. No filter is included in this listing.
Make sure the fluid is coming from the pan. Clean the area, drive, and look for where the wet line starts. Fluid that starts higher, at the cooler lines or the case, will run down and drip off the pan without the pan being at fault. If you are also chasing shift complaints, check the level at the correct temperature first, since a low level from a leak causes many of the same symptoms as worn parts. On 2020-2023 trucks with the 850RE, Stellantis issued a D clutch repair bulletin tied to P0733-00, P1DA8-00 or P1D92-00, and a new pan will not cure that. Our Charger 8HP common problems and Grand Cherokee 8HP common problems guides cover what else to rule out.
The listing covers the 8-speed automatic in the 2013-2023 Chrysler 300 RWD, 2013-2023 Dodge Charger RWD, 2015-2023 Challenger RWD, 2014-2023 Durango, 2014-2023 Jeep Grand Cherokee, 2013-2023 Ram 1500 and 2019-2021 Ram 1500 Classic. It also names the 2019-2021 Ram 2500 and 3500, but heavy-duty Rams of those years were not built with the eight-speed, so confirm your transmission before ordering. Many V6 versions of these vehicles use the 845RE rather than the 8HP70, and all-wheel-drive cars may differ from the RWD fitment shown. The safest check is to match the OE number on your old pan to one in the list above, or send us your year and VIN. More eight-speed parts are in our ZF 8HP collection.
Use the correct ZF eight-speed fluid. Stellantis lists Mopar 68218925AB for these transmissions and states it is not compatible with ATF+4. A 7-liter pack of ZF LifeguardFluid 8 covers the refill. If you would rather stay with the factory style and get a new filter in the same box, the 8HP70 plastic pan, filter and ATF kit is the alternative. The 8HP filter and pan service guide explains what to read on the old magnets.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It includes the pan, gasket and mounting bolts. The factory plastic pan has the filter molded in, so the old filter leaves with it and you need a separate filter on the valve body before installing this pan.
Only if that car has the 8HP70 or 8HP75. Many V6 cars use the 845RE. Match the OE number on your old pan to the replaced numbers on this page, or send us your VIN.
An aluminum pan holds its flange flat under bolt torque and resists cracking from road debris, which are the two usual reasons a plastic pan starts leaking.
ZF eight-speed fluid only. Stellantis lists Mopar 68218925AB and warns it is not compatible with ATF+4. ZF LifeguardFluid 8 is the ZF equivalent. Add no additives.
With the vehicle level and the engine running, bring the fluid to 30-50 C on a scan tool, cycle the gears, open the side fill plug and fill until fluid just runs out, then close it at single drops.
