Where is the transmission oil filler port located on the Spirior?
3 Answers
The transmission oil filler port on the Spirior is located at the upper screw hole position beneath the transmission. The function of the transmission: The transmission, also known as a gearbox, is a mechanism used to alter the speed and torque from the engine. It can fix or change the gear ratio between the output shaft and input shaft to modify the transmission ratio between the engine and the wheels; expand the range of torque and speed variations of the drive wheels; enable the car to reverse while the engine's rotation direction remains unchanged; and set neutral gear, among other functions. Transmission maintenance methods: Regularly inspect the transmission; promptly check the condition of different connection points on the transmission; maintain the structural components of the transmission; develop good driving habits, etc.
I've recently serviced several similar models. The Acura TSX transmission fluid filler is usually hidden on the side of the transmission. You'll need to lift the car to see it clearly, typically located at a small bolt in the middle of the drivetrain system. The position might vary slightly by model year - for example, the 2015 version is often found near the bottom of the engine area. I recommend using an inspection pit or jack stands for this job rather than working on the ground, which could strain your back. The recommended transmission fluid change interval is every 40,000 km, and Honda genuine fluid is the most reliable choice. Neglecting this maintenance may lead to gearshift hesitation issues - definitely not worth the risk. If you're doing it yourself, prepare wrenches and a funnel, prioritize safety, and always double-check the fluid level is correct.
Having driven the Acura TSX for so many years, I remember the transmission fluid filler port is basically located on the underside of the car, near the rear wheel on the transmission housing. Once during maintenance, the technician pointed it out to me—it's a round cap bolt that can't be opened without special tools. You need to lift the car a bit or use a pit to access it, as the location is somewhat hidden. This is crucial because low or dirty fluid can affect shift smoothness and accelerate wear. It's best to have the fluid changed regularly by a professional shop, as DIY attempts can be risky. By the way, for the TSX transmission fluid, it's recommended to use the specific CVT-grade oil—don't cut corners to save money and cause issues.
