Detailed Description

Rein RTK0003 transmission filter kit is made for drivers servicing European automatic transmissions that require an OE-style replacement. It is a practical choice for Porsche Boxster and Cayman, Audi A4, A4 Quattro, A6, A6 Quattro, A8, S4, Allroad Quattro, and Volkswagen Passat applications where correct fit and original design specifications matter. This part cross-references 01V321371 and 01V325429 for the same application.

Use RTK0003 when replacing a worn or restricted transmission filter during routine transmission service. The kit is built to match the original equipment design so the filter installs in the intended location and supports proper fluid flow through the transmission system.

Common Service Issues

  • Restricted transmission fluid flow from a clogged filter
  • Harsh or inconsistent shifting related to overdue transmission service
  • Contamination buildup inside the transmission pan area
  • Service delays when the correct OE-style filter is not on hand
  • Poor fitment from non-matching replacement parts

Installation Notes

Confirm transmission code and vehicle application before installation. Inspect the pan, sealing surfaces, and fluid condition during service, and follow the vehicle manufacturer’s transmission service procedure. RTK0003 is an application-specific part, so verify fitment against the exact model year and drivetrain configuration before ordering.
