Gasket and seal overhaul kit for the VW 01M four-speed automatic, with pan and case gaskets, O-rings, sealing rings and axle seals for Jetta and Beetle.
If your Jetta, Golf, GTI, New Beetle or Cabrio with the four-speed automatic is dripping red fluid under the bell housing or at the axles, engages slowly after sitting, or is already on the bench with the case split, this is the soft-parts half of the job. It is a complete gasket and seal set for the VW 01M: pan gasket, case and cover gaskets, a full spread of O-rings, the Teflon-type sealing rings for the rotating shafts, and the front pump seal plus both axle seals. Every piece is visible in the photos, so you can check the contents before the old parts come out.
The 01M is an electronically controlled four-speed built for VW by STA in France, closely related to the Renault AD4. Clutches K1, K2 and K3 and brakes B1 and B2 are applied by oil pressure that the transmission control module regulates through solenoids in the valve body. Each piston is sealed, each rotating shaft passes oil through sealing rings, and the case halves and covers rely on gaskets and O-rings to keep that pressure in. The unit has no dipstick, and its ATF cooler sits on top of the case and exchanges heat with engine coolant. When the rubber hardens from years of heat, oil escapes past the seals, the clutches apply slowly, and slip and heat build on each other. This kit replaces every one of those sealing parts in one order.
Find the leak first. Clean the case, drive the car, and trace wet areas to their highest point: pan and cover gaskets, axle seals and the fill tube are the usual spots. For a slipping complaint, pull a sample and compare it with our ATF color and smell chart; burnt fluid and friction material in the pan mean the clutches are worn and a seal kit alone will not fix it. Our shift flare vs slip guide explains how to tell a pressure leak from worn frictions. The 01M rebuild kit buyers guide compares the kit levels.
This kit is listed for VW Cabrio, Jetta and Beetle with the 01M automatic, and the same transmission was used in the Golf and GTI between 1995 and 2005. It does not include frictions, steels or a filter. The 01P in the Eurovan and the 01N in longitudinal Audis share many internals but are different units, so confirm the code on the transmission case or send us your year and VIN before ordering.

No. It is the gasket and seal portion of a rebuild: gaskets, O-rings, sealing rings and the front and axle seals. If the K1 or K3 frictions are burnt, add a friction set or choose a master kit instead.
It is listed for the VW Cabrio, Jetta and Beetle with the 01M four-speed automatic. The same transmission was used in the Golf and GTI from 1995 to 2005. Check the transmission code on the case or send us your year and VIN to be sure.
Yes. The axle seals in this kit can be replaced with the transmission in the car after the drive flange is removed. Many owners keep the rest of the gaskets for later, but if the car is also slipping, plan on a full teardown.
VW built it without one. The level is checked at the check plug with the fluid at the specified temperature, usually using a scan tool to read fluid temperature. Overfilling or underfilling both cause shift problems.
Yes. Clear the stored adaptation values with a VW-capable scan tool after reassembly, then drive the car through all four gears so the module relearns shift timing for the new seals and clutches.
