Short answer: If your LaCrosse has a traditional dipstick, you can check the fluid level at home using the engine-warm procedure outlined below. If your model is sealed and lacks a dipstick, a dealer or qualified technician must perform the level check and service.
In this article, we explain how to determine whether your car has a dipstick, how to check the fluid if you do, and what to do if the transmission is sealed and not designed for at-home maintenance. Accurate fluid level and specification are important for smooth shifting and long transmission life.
Does the 2014 Buick LaCrosse have a transmission dipstick?
GM-era transmissions can either have a traditional dipstick or be sealed, depending on production and configuration. The safest approach is to confirm by consulting the owner's manual or checking for a dipstick in the engine bay. If you see a bright-handle dipstick labeled for transmission fluid, you have a dipstick-equipped transmission you can check at home. If there is no dipstick and only fill/inspection ports, the level must be checked with specialized tools by a technician.
Use this checklist to determine whether you can check the fluid at home or need professional service:
- Dipstick present and accessible in the engine bay: home check is possible following the steps below.
- No dipstick; sealed transmission: home check is not recommended; rely on a dealer/qualified shop for proper level check and servicing.
Note: If your LaCrosse is the sealed-type configuration, attempting a DIY fill or pan draining without the proper GM service tools can risk incorrect level and potential transmission damage. When in doubt, consult your owner’s manual or contact a GM-certified technician.
If you have a dipstick: step-by-step procedure
Before starting, ensure you have the correct Dexron VI transmission fluid, a clean funnel, and a clean rag. Perform the check with the engine at operating temperature and the car on level ground.
- Warm up the engine to operating temperature by driving for 10–15 minutes, then let the engine idle for a few minutes. A hot reading is required for accuracy.
- Park on level ground, set the parking brake, and keep the engine running with the transmission in Park (P).
- Open the hood and locate the transmission dipstick (often labeled and color-coded). Remove the dipstick, wipe it clean with a rag, reinsert fully, then pull it out again to read the level.
- The fluid level should be between the two hot marks on the dipstick when the transmission is at operating temperature. If it’s low, add Dexron VI fluid a little at a time through the dipstick tube using a clean funnel, then recheck.
- After achieving the proper level, reinsert the dipstick and run the transmission through the gears (Park, Reverse, Drive, etc.) with the engine running to circulate the fluid. Recheck the level and avoid overfilling, which can cause foaming and shifting issues.
Concluding note: Following the manufacturer’s hot-range readings and using the recommended Dexron VI fluid helps ensure proper shifting and longevity of the transmission.
No dipstick: professional level check and service
If your 2014 LaCrosse does not have a dipstick, the transmission level is not intended to be adjusted by the owner. A dealer or qualified technician will perform the level check using the correct GM service tools and procedures, typically with the vehicle warmed to specification and the level read via a designated port or scan tool.
Before you proceed with any service, understand these common steps technicians follow:
- Connect GM service tools to read transmission temperature and perform a level check to established specifications.
- Use Dexron VI ATF that meets GM specifications and fill through the proper port until the level is within the manufacturer’s target range.
- Test-drive to ensure proper shifting and verify there are no leaks or warning codes.
Conclusion: For sealed transmissions, home maintenance is limited. Rely on a GM-certified technician for accurate level checks, appropriate fluid specification, and any necessary servicing to prevent damage and preserve performance.
Fluid type and maintenance tips
Dexron VI and compatibility
Use Dexron VI transmission fluid or an equivalent GM-approved fluid that meets Dexron VI specifications. Do not mix fluids of incompatible types, and always follow the exact fill specification in your owner's manual or service guide. Regular checks and timely replacement per GM recommendations help maintain smooth shifting and prevent overheating or wear.
What to watch for between checks
Pay attention to symptoms that may indicate low or degraded transmission fluid, including reluctance to shift, slipping, hard or delayed shifts, strange noises, or unusual exhaust smoke near the transmission area. If you notice any of these signs, have your vehicle inspected promptly by a qualified technician.
Summary
For the 2014 Buick LaCrosse, the ability to check transmission fluid at home depends on whether your transmission has a dipstick. If you do have a dipstick, follow the hot-level procedure with Dexron VI fluid and avoid overfilling. If your car is sealed, home checks are not advised; rely on a GM-certified technician who uses the correct tools and specifications. Regular maintenance, correct fluid type, and timely service are essential for smooth shifting and transmission longevity.
Can you just add transmission fluid to your transmission?
Simply remove the dipstick and insert the funnel into the hole. Pour the correct fluid slowly into the funnel. Add a little bit of fluid at a time so you do not overfill—you can always add more, but it's very difficult to take fluid out.

How do you check the transmission fluid on a Buick?
Find the transmission fluid dipstick. On front-wheel-drive cars, it's usually located to the right of the oil dipstick. Check your owner's manual if you're having trouble finding it. Remove the dipstick and touch the fluid, moving it around between your thumb and forefinger.

How do I tell if my transmission fluid is low?
If your gears are slipping, it's a clear sign your car's running low on transmission fluid. When experiencing sudden up and down shifts, high RPMs right before shifting, or erratic shifting, seek assistance from your local service center to prevent your transmission from overheating or becoming damaged.

And it should be dry. As much as you can stick the dipstick back in close the lid. And take the lid back out.
