What transmission fluid does a Jeep Compass use?

The Chassis Fluids And Lubricants chart in the 2026 Jeep Compass Owner's Manual says to use only Mopar ZF 8 & 9 Speed ATF Automatic Transmission Fluid, or equivalent, in the automatic transmission. It adds that failure to use the correct fluid may affect the function or performance of your transmission.

The maintenance section explains why: it is important to use the proper transmission fluid to ensure optimum transmission performance and life, and to maintain the fluid at the correct level using the recommended fluid. Using a transmission fluid other than the manufacturer recommended fluid may cause deterioration in transmission shift quality and/or torque converter shudder.

Why there is no transmission dipstick

The 2026 manual says the fluid level is preset at the factory and does not require adjustment under normal operating conditions. Routine fluid level checks are not required, therefore the transmission has no dipstick. An authorized dealer can check your transmission fluid level using special service tools.

If you notice fluid leakage or a transmission malfunction, the manual says to visit an authorized dealer immediately to have the transmission fluid level checked. Operating the vehicle with an improper fluid level can cause severe transmission damage, and an authorized dealer has the proper tools to adjust the fluid level accurately.

When is Compass transmission fluid changed?

Under normal operating conditions, the 2026 manual says the fluid installed at the factory will provide satisfactory lubrication for the life of the vehicle, and routine fluid and filter changes are not required. It says to change the fluid and filter if the fluid becomes contaminated (with water, etc.), or if the transmission is disassembled for any reason.

The Maintenance Plan tables in the same manual run from 20,000 to 150,000 miles and have no automatic transmission fluid line. The manual also notes that more frequent maintenance may be needed in severe conditions, such as dusty areas and very short trip driving. If you tow, drive off-road or see a leak, ask our service advisors about your Compass.

What not to put in the transmission

The 2026 manual lists three things to avoid:

• No special additives. The manual strongly recommends against using any special additives in the transmission. Automatic Transmission Fluid (ATF) is an engineered product and its performance may be impaired by supplemental additives. The only exception it gives is special dyes for diagnosing fluid leaks in 8-speed transmissions.
• No sealers. Avoid using transmission sealers, as they may adversely affect seals.
• No chemical flushes. Do not use chemical flushes in your transmission, as the chemicals can damage transmission components. The manual says such damage is not covered by the New Vehicle Limited Warranty, and that only the approved lubricant should be used.

Transmission warning lights

From the 2026 Jeep Compass Owner's Manual (transmission warning lights, page 92), read November 4, 2026.

Limp Home Mode, resetting the transmission and the torque converter clutch

The manual says transmission function is monitored electronically. If a condition is detected that could result in transmission damage, Transmission Limp Home Mode is activated: the transmission may operate only in a fixed gear or remain in NEUTRAL, and the Malfunction Indicator Light may be illuminated. Limp Home Mode may allow the vehicle to be driven to an authorized dealer without damaging the transmission.

For a momentary problem, the manual gives a reset: stop the vehicle, shift into PARK if possible (otherwise NEUTRAL), push and hold the ignition until the engine turns off, wait about 30 seconds, restart and shift into the desired gear. Even if the reset works, it recommends visiting an authorized dealer at your earliest convenience.

The manual also notes that the torque converter clutch will not engage until the engine and/or transmission is warm, usually after 1 to 3 miles of driving, so it may seem as if the transmission is not shifting properly when the vehicle is cold. It calls this normal.

4x4 models: PTU and rear differential fluids

The 2026 Compass four-wheel-drive system, Jeep Active Drive, uses a Power Transfer Unit (PTU). The fluid chart lists separate lubricants for it and the rear differential, if equipped:
