Check ATF Clarity and Temperature Before Deciding on Service
The AS505 dips an optical probe into transmission fluid and shows its transmittance, fluid temperature and a clear status prompt on one backlit screen. Treat the reading as a screening reference alongside the vehicle condition, not as a stand-alone replacement decision.

Key Features
-
Sonde de transmission optique
An integrated photoelectric transceiver sensor gives stable feedback on fluid clarity. Reduced transmittance may point to impurities, deposits or metal contamination.
-
Tuyau flexible en Teflon
Reaches service points easily and resists oil, oxidation and corrosion.
-
Affichage de température du liquide
A built-in sensor shows the current fluid temperature, switchable between °C and °F.
-
Indicateurs de résultat clairs
OK for 100–50% transmittance, Warning for 50–30%, and Suggested Replacement below 30%, plus an analog bar graph.
-
Lisible sous tout éclairage
The backlit LCD stays legible in daylight, dim workshop corners or at night.
-
Utilisation à une main
A silicone-lined grip and light body make single-handed testing comfortable.

How to Use
- AllumerInstall four 1.5 V AAA batteries with correct polarity, then hold the power key for more than 2 seconds.
- Wipe the probeClean the probe tip so old oil or dirt does not affect the reading.
- Vérifier la températureMake sure the engine is below 60 °C; switch between °C and °F if needed.
- Immergez la sondePlace the probe in the transmission fluid and keep it properly immersed.
- Test and readPress the test button and read transmittance and fluid temperature on the display.

Good to Know
Attention
- Effectuez le test uniquement lorsque la température moteur est inférieure à 60 °C.
- Batteries are not listed in the package; prepare four 1.5 V AAA batteries.
Entretien
- Essuyez la sonde avant chaque mesure.
- A check every 5,000–10,000 km is recommended before deciding on transmission fluid service.
- For viscosity, wear metals or remaining service life, use the specified laboratory tests.
FAQ
Le AS505 remplace-t-il ou rince-t-il le liquide de transmission ?
No. It only tests fluid transmittance and temperature; it does not drain, flush or refill.
Can it test engine oil, brake fluid or power steering fluid?
It is designed for transmission fluid. Use the AS503 for engine oil, the AS501 or AS502 for brake fluid water content, the AS506 for brake fluid boiling point and the AS507 for power steering fluid.
