About this product
When hydraulic filter automatic transmission performance matters, the KNECHT HX 256D delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Transmission Type: 23, Length [mm]: 202, Carbon mm, Width [mm]: 124 mm, Height [mm]: 30, Rubber mm, Supplementary Article/Supplementary Info: 35. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. Compatible with SEAT, SKODA, VW vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 09G 321 370, 09G321370, 09G325429A, 1003250009 and 5 more. Matching these numbers confirms a like-for-like replacement with no loss of function.
