68RFE Heavy Duty Cast Aluminum Transmission Oil Pan

If the stamped pan under your 6.7L Cummins Ram has a dent from a rock, a ledge or a jack in the wrong spot, or you tow hard and want more margin on fluid temperature, this is the part people search for: a heavy duty cast aluminum oil pan for the Chrysler 68RFE in 2007-2025 Ram 2500 and 3500 trucks. It replaces pan part number 228052110 (OE equivalent 228052100). The casting measures 19.1 x 6.2 x 6.4 inches. It is the pan only; the gasket and filter are bought separately.

What the oil pan does in a 68RFE

On the 68RFE the pan is the fluid reservoir for a six-speed that sits behind one of the highest-torque engines in a pickup. The pump draws from the pan through the filter and feeds line pressure to the valve body, solenoids and clutch packs, and every drop of ATF+4 that has been through the converter and cooler drains back into it. Two things go wrong with a stock stamped pan. A dent pushes the pan floor up toward the filter inlet, which can unseat the filter or restrict its pickup, and a pump that pulls air will not hold pressure. The pan also has to shed heat. Heat is what breaks down ATF+4 and what finishes off clutch packs when line pressure is marginal. A thick aluminum casting adds mass and surface area, and it will not fold up when something hits it.

Symptoms that point to the pan or the fluid supply

• A visible dent or crease in the pan floor, or a weep at the pan rail after an impact
• Pump whine or a buzzing noise that changes with engine speed
• Delayed engagement into Drive or Reverse, worse when the fluid is cold or the level is low
• Fluid temperature that climbs fast on grades or with a trailer
• Slipping or flare in the upper gears, where the 68RFE's overdrive clutch is most sensitive to low pressure and heat

How to confirm before you buy

Get under the truck and look first. A pan that is dented upward is worth replacing even if the truck still shifts well, because the filter problem it causes usually shows up under load. If there is no damage but you have noise or slow engagement, check the fluid level hot and look at what is on the magnet and in the bottom of the pan. Fine gray paste is normal wear; clutch material, brass flakes or metal chunks mean a bigger problem than the pan. Our 68RFE pump failure guide walks through the pressure checks that separate a supply problem from a worn pump, and the high-mileage service checklist covers what to inspect while the pan is down.

Fitment

This pan is listed for the 68RFE in 2007-2025 Ram 2500 and 2007-2025 Ram 3500 pickups with the 6.7L Cummins. The 68RFE arrived with the 6.7L partway through the 2007 model year, so an early 2007 truck with the 5.9L and a four-speed is not a match. Ram 3500 trucks with the high-output engine use the Aisin AS69RC instead, which has a different pan. Look at the transmission before you order, match the old pan to part number 228052110 or 228052100, or send us your year and VIN and we will check it. Everything else we carry for this unit is on the 68RFE parts page.

Install notes

• Drain as much fluid as you can before loosening the pan, then remove the bolts in a cross pattern and leave two at opposite corners until last.
• Clean both sealing surfaces to bare metal. Old gasket or RTV left on the case rail is the usual cause of a leak on a new pan.
• Run the bolts in by hand and torque them evenly with an inch-pound torque wrench. Do not use an impact on an aluminum pan.
• Replace the filter and gasket every time the pan comes off. The 4WD filter and gasket kit and the 2WD filter kit are listed separately, so pick the one for your drivetrain.
• Refill with ATF+4 only, then set the level with the engine running and the fluid at full operating temperature. Ram's recall service instructions call for at least 160 F before the level is set.

If the truck tows and runs hot even with a healthy pan, look at the cooler circuit as well; the ZeroStat cooler bypass kit is the common fix for a thermal bypass that holds fluid away from the cooler.

Does this 68RFE pan come with a gasket and filter?

No. It is the cast aluminum pan only. Order a filter and gasket kit for your truck at the same time, because both should be replaced any time the pan is removed. 2WD and 4WD trucks use different filter kits.

Will it fit a Ram 3500 with the high-output Cummins?

Only if that truck has the 68RFE. High-output 3500 trucks use the Aisin AS69RC, which has a different pan and does not take this part. Check the transmission or send us your VIN.

What fluid goes in after the pan swap?

ATF+4 only. Ram's owner's manual states the 68RFE behind the 6.7L diesel must use ATF+4. Check the level with the engine running and the fluid hot, at least 160 F.

Why would I replace a pan that is not leaking?

A dent can lift the pan floor into the filter and cause the pump to pull air under load, which shows up as noise, delayed engagement or slipping. A cast pan also adds heat capacity on trucks that tow.

What torque do aluminum pan bolts take?

Use the factory inch-pound value for the 68RFE pan bolts and a torque wrench, tightening evenly in a spiral from the center out. Over-tightening with an impact can strip threads or distort the sealing flange.
