Drop-in replacement pan for Chrysler, Dodge, Jeep and Ram ZF 8-speed transmissions, with a built-in drain plug and a serviceable, replaceable filter.
The Dorman 265-850 is the pan to buy when your Ram 1500, Charger, Challenger, Chrysler 300, Durango or Grand Cherokee eight-speed is due for fluid, or the factory pan is seeping at the flange, and you want the job to be cleaner and cheaper the next time. It is a plastic, OE-style replacement for the ZF 8HP pan with two changes that matter: a threaded drain plug, and a filter that can be replaced on its own with Dorman's 265-850F kit. The box contains the pan, a gasket and the mounting bolts.
On the Chrysler-built eight-speed the factory pan carries the filter molded into it. That design is why a dealer fluid service on these vehicles often turns into a pan replacement: you cannot change the filter without changing the pan. It also has no drain, so dropping it means a lap full of ATF. The Dorman pan keeps the stock shape, the stock bolt pattern and the stock look, so nothing else under the vehicle has to change, but it separates the filter from the pan and gives you a plug to empty it first.
Because it matches the factory depth, it adds no capacity and needs no extra clearance. That makes it a good fit where a deep aluminum pan would hit a crossmember or exhaust, and for owners who simply want a stock-style repair.
Many 8HP leaks that look like a pan leak come from the cooler lines or the mechatronic sleeve above the pan, so clean the area and find the wet spot before you buy. Check the fluid level at the fill plug, not by guesswork, and pull codes. If the vehicle has a shift complaint, work through our Grand Cherokee 8HP shift problem guide or the Charger 8HP common problems guide; FCA has published software and valve body fixes for several complaints that a pan and fluid will not touch. If the cause is a pressure control fault, the 8HP pressure control solenoid guide covers testing.
This pan is for the ZF 8HP45 and 8HP70 family used in FCA vehicles from about 2013 on: Ram 1500, Chrysler 300, Dodge Charger, Challenger and Durango, and Jeep Grand Cherokee. Dorman's own list runs later and adds models such as the Wagoneer, so year coverage is broad, but trim and drivetrain still matter. The factory plastic pan numbers it replaces include Mopar 68225344AA and 52854834AB; compare the number on your pan, or send us your year and VIN, before ordering. All eight-speed parts are on our ZF 8HP collection page.
If the inspection turns up worn solenoids or the job becomes a rebuild, see the 8HP70 solenoid kit or step up to the aluminum 8HP70 pan that replaces 265-850 if you would rather have a metal pan in the same factory depth.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The pan is built around Dorman's replaceable 265-850F filter, and that kit (filter, gasket and screws) is what you buy at later services. When you install the pan, confirm a 265-850F filter is fitted inside before it goes on, because the factory filter leaves with the old pan.
It is plastic, the same style as the factory pan, so it keeps stock depth and clearance. If you want metal at the same depth, we also carry an aluminum pan that replaces 265-850.
FCA vehicles with the ZF eight-speed from about 2013 on, including Ram 1500, Chrysler 300, Dodge Charger, Challenger and Durango, and Jeep Grand Cherokee. Match your stock pan number, such as 68225344AA or 52854834AB, or send us your year and VIN.
FCA calls for Mopar ZF 8 and 9 speed ATF or an equivalent in its ZF eight-speeds. Set the level at the fill plug with the fluid at 30-50 C.
Check that the gasket is seated and the bolts were tightened crosswise in stages. If the flange is dry, the leak is likely above it, at the cooler lines or the mechatronic connector sleeve, which is a common 8HP leak point.
