Mk4 Golf / Golf A4 TDI 02M / 5 Speed to 6 Speed Gearbox Conversion Kit

This Kit has been put together to allow you to upgrade your 5 Speed Manual to the 6 Speed in the A4/Mk4 Golf and Jetta with the ALH or BEW Engine Code

The price displayed includes DHL Express Shipping to the USA and Canada. Extra shipping costs may apply to all customers outside of the USA and Canada - Please contact us

The standard 5 to 6 Speed setup comes with all the you need to upgrade from a 5 Speed Manual to the 6 Speed in the A4/Mk4 Golf and Jetta with the ALH or BEW Engine Code. A few more parts are needed to swap out an Automatic Transmission.

PLEASE NOTE: There are multiple options and extra parts available with this kit. Please read the FULL listing as it will outline and explain what can be added and what is included.

Please see below kit options and description:

Gear Shifter Cables:

This adds a used set of Gear Shifter Cables / Linkage to the order. This option is NOT required for 5 speed transmissions as the originals will work. It is available just in case the originals are damaged / unusable.

This also does not need to be selected when choosing the Auto to Manual setup as they are included within that option

6 Speed Clutch Fluid Line

Again, this is not required with the 5 speed manuals but will save bending your stock hose to work on the 6 speed.

We have the OEM Clutch Line OR Our Braided Clutch Line available (select from the relevant option)

This also does not need to be selected when choosing the Auto to Manual setup as the OEM Clutch Line is included within that option

Driveshafts / Axles

With these vehicles now approaching 20+ years old, the Genuine Driveshafts are hard to come by in Good Condition. We source Genuine Used Driveshafts to supply with the kits, but the condition is not always the best. We have added options to this listing allowing you to customise the kit and select from certain Axle options to ensure your TDI 6 Speed Conversion is exactly how you want it.

Used Drivehshafts - A Pair of USED driveshafts in USED condition. If we believe these driveshafts are unusable / in need of repair, we will email you after ordering to inform you if or what work needs to be carried out in order for the driveshafts to be usable. Additional funds may be requested for this if we have to repair / change any joints / boots.

Used Driveshafts with NEW OE CV Joints - A Pair of USED driveshafts fully rebuilt with OE quality CV Joints & Boots (Inner & Outer)

New OE Quality Driveshafts - A Pair of BRAND NEW OE Quality Driveshafts. Although these are pricey, these are the highest quality Aftermarket / OE quality driveshafts on the market

New Aftermarket Driveshafts - A Pair of Aftermarket Driveshafts from various aftermarket suppliers. These are NOT suitable for high performance vehicles
