01M Overhaul Kit 2001-2006, new and ready to install. Fits the 01M. Ships fast from the USA.
This overhaul kit is built for the later VW 01M four-speed automatic in 2001-2006 Volkswagen Jetta and the matching Mk4 Golf and New Beetle applications. Unlike a plain seal kit, it includes molded pistons and covers plus single-sided 3-4 friction plates, so it handles the parts that most often wear out when a high-mileage 01M starts slipping on the 3-4 shift or leaking pressure. Paper gaskets, lip seals, O-rings, the pan gasket and metal-clad and Teflon sealing rings round it out.
The 01M is a transverse four-speed with an integrated final drive, fitted to Mk3 and Mk4 VW Jetta and Golf and to the 1995-1997 Passat. Each gear is engaged by a hydraulic clutch or brake, and the TCM controls it through the solenoids in the valve body. Molded pistons apply those clutches; when their rubber hardens or the sealing rings wear, apply pressure drops and the clutch slips. Glazed or burned 3-4 frictions are a common find in a tired 01M that flares between 3rd and 4th, which is why it helps that this kit includes new single-sided 3-4 frictions in addition to the seals and pistons.
Check the fluid first. The 01M has no dipstick; the level is set at the check plug with the fluid at about 35-38 C, and a low level alone can cause flares and fault 00652. Our transmission slipping diagnosis guide covers the order of checks, and shift flare vs slip explains how to tell a pressure or solenoid problem from worn clutches. If the fluid is burned and the 3-4 frictions are glazed, a rebuild with this kit is the right move.
The kit is listed for the 01M from 2001-2006, including the 2001-2006 VW Jetta. The original listing also mentions the Passat VR6 for these years, but most 1998-2005 Passats used the five-speed 01V rather than the 01M, so check the code on your transmission before ordering; a Passat with the 01V needs a different kit. The 01M Jetta also ran Tiptronic and non-Tiptronic valve bodies, though the soft parts in this kit are shared. Match your pan gasket style, since the kit notes cork, fiber or molded rubber depending on model, and send us your year and VIN if you want a second check. Earlier units are covered by the 01M overhaul kit for 1996-2005, and full kits with every friction are under rebuild kits.

It includes molded pistons and covers and single-sided 3-4 friction plates. It does not include the other friction packs, steels or a filter.
Most Passats from those years use the 01V five-speed, not the 01M. Check the transmission code; this kit is for the 01M only.
VW ATF to spec G 052 162 A2, filled and checked at the check plug with the fluid around 35-38 C. The final drive uses separate gear oil.
Only if worn clutches caused it. Rule out low fluid, solenoid faults and the valve body first, then clear codes and run the adaptive relearn after the rebuild.
The seals, gaskets and pistons are shared. The valve bodies differ, so if you replace the valve body, match it to your version.
