OE-style automatic-transmission fluid filler tube for compatible Volkswagen four-speed automatic transmissions. Replace cracked or brittle original tubes during service.
$15.00
The 01M 321 407 fill tube is an automatic-transmission fluid filler tube for compatible Volkswagen models equipped with a four-speed automatic transmission. This molded plastic component provides the correct path for adding transmission fluid during maintenance and helps close off the transmission from outside contamination when installed with the correct related sealing components.
Heat cycles, age, impact damage, and brittle plastic can cause the original tube to crack or deteriorate. Replacing a damaged tube supports clean fluid service and protects the transmission from contaminants entering through the filler opening.
Automatic transmissions require clean, manufacturer-specified fluid at the correct level. A cracked, loose, or missing filler tube can expose the transmission filler area to dirt, moisture, and debris. Contamination can affect hydraulic passages, solenoids, and valve-body operation.
Inspect the transmission filler area if you notice:
Cracks, splitting, distortion, or brittle plastic around the tube.
A loose or missing transmission filler cap.
Fluid residue near the fill-tube connection.
Dirt or moisture accumulating around the filler opening.
Damage found while performing automatic-transmission fluid service.
