Full specifications by generation

The fluids on a Ram 1500 is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

Ram 1500 fluids: common questions

What transmission fluid does a Ram 1500 take?

ZF-based TorqueFlite 8-speed (8HP75/8HP75-LCV, 870RE on TRX): Mopar ZF 8&9 Speed ATF (68218925AB), sealed, no dipstick, level set by temperature/overflow procedure. No scheduled change in normal service; ~60,000 mi change is common practice for heavy towing.. Transmission fluid specifications are not interchangeable. Friction modifiers differ between them, and the wrong fluid causes shudder long before it causes failure.

What coolant does a Ram 1500 use?

Mopar OAT coolant (MS.90032); 10-yr/150k first change, then every 5 yr. eTorque and Hurricane trucks have additional low-temp cooling loops, bleed per service info..

What brake fluid does a Ram 1500 take?

DOT 4 brake fluid (check the reservoir cap label; flush every 2–3 years is good practice).

What differential fluid does a Ram 1500 take?

Rear axle synthetic 75W-85 GL-5 (75W-140 for heavy towing per tag); front axle 75W-85 GL-5.
