Description

VW T3 4 speed HD TDI Gearbox Rebuild Repair Service. This is our Gold standard VW T3 HD TDI 4 speed gearbox build/repair service and results in the strongest TDI 4 speed gearbox you can build. This comes in at a reduced cost of €3899 plus shipping ( I can get your gearbox collected and shipped to me for approx. 60 euros for nearly anywhere in Europe including the UK) . To secure this service you will be charged a €2000 deposit upon checkout. You will be contacted by us by email to confirm receipt of your deposit and you will receive instructions on how to send your gearbox to us. The balance of €1899 plus any authorised costs will then be invoiced to you later, in the final invoice for your rebuild.

The service involves the replacement of all common wear items and some upgrades to rectify known faults. We rebuild gearboxes to the original VW factory tolerances, to do that it is necessary to replace all the consumable wear items, i.e. bearings, seals, and bushes. We also replace single-use parts such as circlips as per the factory rebuild procedure and replace the synchro rings. All bearing preloads and backlash is measured meticulously, and the box is set up accordingly. Our aim is to restore your box to as close to new as possible or even stronger than new with some upgrades.

If your gearbox is broken it will need this service plus whatever components replacing that are not covered here. If you are wishing to upgrade your box to accommodate and engine conversion you will also need this service plus whatever parts you require.

Until we inspect your box it is very hard to give you a more accurate quote on what it needs. Upon receipt of your service booking fee, we shall supply you with shipping instructions on how to send your gearbox to us. We have currently secured very low prices from our courier company for shipping .

Usually, within two weeks of receiving your gearbox, we shall give you a full professional inspection report and suggestions for your rebuild. These are to suit various budgets from low to high. You will then decide on the option you would like and pay the balance. Your box will be built to your specifications and shipped to you with a build report for your records. All shipping is insured.
