The Buick Encore generally uses Dexron VI automatic transmission fluid and can be checked with an accessible dipstick when the transmission is at normal operating temperature and the vehicle is on level ground. If your model year uses a sealed transmission with no dipstick, fluid level checks must be done by a dealership or qualified technician. This guide covers both scenarios and explains what to look for in terms of fluid level, color, and odor.
Checking transmission fluid with a dipstick
Use this method if your Buick Encore has a visible transmission dipstick. The steps below assume the engine is warmed to normal operating temperature and the car sits level on the driveway or lot. Always use Dexron VI ATF or an equivalent GM-approved fluid.
- Park on level ground and engage the parking brake for safety.
- Start the engine and allow the transmission to reach normal operating temperature by driving for about 10–15 minutes, then let the engine idle.
- With the transmission in Park (P) and the engine running, locate the transmission dipstick.
- Pull the dipstick out, wipe it clean with a lint-free rag, reinsert it fully, then pull it out again to read the level.
- Read the level against the hot-range marks. The fluid should be between the ADD and FULL marks on the hot scale. If it’s below the ADD mark, you’ll need to add fluid.
- To add fluid, remove the dipstick again and slowly pour a small amount (about 1/4 quart) of Dexron VI ATF through the dipstick tube using a clean funnel. Recheck after adding.
- Cycle the transmission through the gears (P-R-N-D) a few times to distribute the new fluid, then recheck the level.
- Avoid overfilling. Overfilled transmissions can foaming and cause shifting issues. If you accidentally overfill, remove some fluid or have a professional drain the excess.
- Inspect the fluid’s color and smell. Fresh Dexron VI ATF is pink/red and should not have a burnt odor. If the fluid looks dark, muddy, or smells burnt, it may need replacement.
- Secure the dipstick back in place and close the hood.
Notes: Always confirm the dipstick location and the exact hot-range markings in your owner’s manual, as GM may adjust procedures by model year. If you’re unsure at any point, consult a dealer or trusted mechanic.
No-dipstick models: sealed transmissions
Some Buick Encore configurations use a sealed transmission without a user-accessible dipstick. In these cases, a DIY at-home check isn’t practical, and a professional service is required to verify fluid level and condition. Here’s what you should know if your vehicle falls into this category.
- Verify whether your model year has a dipstick by consulting the owner’s manual or contacting a Buick service center.
- If there is no dipstick, schedule a service appointment for a transmission fluid level check and any necessary top-off or replacement using GM-approved procedures.
- Ask the technician to inspect fluid color and odor and to use Dexron VI ATF if a refill is needed.
- Discuss maintenance intervals and service recommendations specific to your model year and driving conditions.
- Avoid driving long distances or heavy towing if there are signs of low or degraded fluid, as this can cause transmission wear or damage.
Dealerships and qualified shops have the equipment to test transmission temperature and perform precise level checks using GM-approved methods for sealed units.
Summary
For Buicks with a dipstick, check the transmission fluid when hot and at level ground, adding Dexron VI ATF in small increments if needed while avoiding overfill. If your Encore has a sealed transmission without a dipstick, rely on a dealer or certified technician to perform a proper level check and fluid replacement using the correct GM procedure. Keeping the fluid clean and at the proper level helps ensure smooth shifts and long transmission life.
