Is it okay to add ATF plus 4 transmission fluid instead of MOPAR in a 1997 Chrysler Sebring automatic?

No, it's not recommended to use ATF+4 in a 1997 Chrysler Sebring automatic transmission unless you're absolutely certain it's compatible. While ATF+4 is a common Chrysler fluid, the 1997 Sebring might use a different type of automatic transmission fluid. Using the incorrect fluid can severely damage the transmission.

Always check your owner's manual. This will specify the exact type and specification of transmission fluid required for your vehicle. The manual should state the fluid type by name and possibly a code. If you don't have the manual, you can often find a digital version online.

Using a substitute fluid without confirmation could lead to:

* Slipping: The transmission might slip gears or not shift properly.

* Internal Damage: Friction modifiers and other additives in the wrong fluid can damage seals and other internal components.

* Complete Transmission Failure: In severe cases, using the incorrect fluid can lead to complete transmission failure requiring a costly rebuild or replacement.

To be safe, stick with the fluid specified in your owner's manual. If you can't find the information, consult a Chrysler dealership or a reputable transmission repair shop for guidance. They can tell you the correct fluid to use.
