❓ FAQ
Yes. KT33501 matches HU 721 y on all three dimensions: 64 mm outer diameter, 31 mm inner diameter and 150 mm overall height, and it comes with the sump gasket.
No. It is the automatic transmission oil filter. The manufacturer classes HU 721 y as a hydraulic filter for automatic transmissions, and it serves the Optidriver and I-Shift gearboxes rather than the engine.
Both are 105 mm family elements but not the same part. KT33501 is 64 mm across with a 31 mm bore and 150 mm height for the gearbox; KH25501 is 60 mm across with an 18 mm bore and 101 mm height for the steering reservoir. They are not interchangeable.
Yes. The sump gasket is supplied with the element, so the seal is renewed at every transmission service rather than reused.
Follow the gearbox maker's interval, which is usually tied to the transmission oil change rather than to the engine service. On heavy-duty or high-mileage duty, shorten it.
