Master overhaul kit of frictions, steels, seals and gaskets to rebuild the JF506E five-speed automatic in VW, Ford, Jaguar, Mazda and Land Rover.
If your Mk4 Golf or Jetta automatic is flaring between gears, your Jaguar X-Type has lost a gear, or a Freelander or Mazda MPV has dropped into limp mode with dark, burnt fluid, the Jatco JF506E inside it is usually ready for a full overhaul. This master rebuild kit puts the soft parts for that overhaul in one box: the friction plates, the steel plates, the sealing rings, the rubber lip seals and the complete gasket set. Volkswagen and Audi call this five-speed the 09A (and 09B), so a VW parts catalog will show it under those codes rather than JF506E.
The JF506E is a compact five-speed automatic with a lockup converter, built in front-wheel-drive and all-wheel-drive versions. Each gear is made by applying a combination of multi-plate clutches and brakes, and every one of those packs is a stack of friction plates splined to one member and steel plates splined to another. When the friction material glazes or wears thin, the pack takes longer to lock, the computer sees the ratio error and commands more pressure, and the heat cycle speeds up. The sealing rings and piston seals are just as important: they hold apply pressure inside the drums, so a hardened seal lets pressure bleed off and a perfectly good pack slips anyway. A master kit renews both halves of that problem at once, which is why it is the starting point for any JF506E teardown.
Scan the transmission control module first. The JF506E also has known internal wiring harness and speed sensor problems, and a bad harness can produce slip-like ratio codes on a unit with healthy clutches. Check fluid level and condition, then road test with live data so you can see whether the slip follows one gear or one clutch. Our transmission slipping diagnosis guide walks through that process, and the ATF color and smell chart helps you judge whether the fluid says burnt clutches or just old oil. If the pan shows heavy clutch debris, an overhaul with this kit is the right call; a few electrical codes alone usually point to the harness or a solenoid instead.
This kit is listed for the JF506E family across roughly 1996 to 2010, depending on chassis: VW Golf, Jetta/Bora and Sharan of the Mk4 era, Audi A3 Mk1, SEAT Alhambra, Ford Mondeo Mk3 and Galaxy, Jaguar X-Type, Land Rover Freelander Mk1 and the Mazda MPV 3.0L V6. Be careful here. The versions built for each maker do not look alike outside, the bellhousings differ, and many internal parts do not interchange; Sonnax notes the Mazda valve body is a different design from the VW, Jaguar and Land Rover units. Read the tag on your case, match the 09A or 09B code on a VW, and send us your year and VIN if you are unsure before ordering.
Hold the clutch stack together during assembly with a firm-tack gel such as Filtran TransJel, and verify endplay with a dial indicator on a magnetic base before the converter goes on.

It is listed for the JF506E family, which VW calls 09A and 09B. The VW, Jaguar, Land Rover, Ford and Mazda builds differ in bellhousing and several internals, so match the code on your case tag or send us your VIN before ordering.
Friction plates, steel plates, sealing rings, rubber lip seals and the full gasket set. It does not include drums, pistons, the pump, solenoids or a torque converter.
Transmission Digest reports frequent direct-clutch failures, sometimes with a damaged high-clutch drum, with the clutch-apply piston as the weak point. Internal harness and speed sensor faults can also mimic slipping, so scan for codes first.
Yes. Reset the transmission adaptations with a capable scan tool and complete a road-test relearn so the control module learns the new clutch fill times.
Use the ATF your vehicle maker specifies for that model; VW, Jaguar, Land Rover, Ford and Mazda each publish their own fill fluid and level-check procedure for this transmission.
