core service
Your VW T3 gearbox, properly rebuilt.
Many T3 owners know the symptoms: gears no longer stay engaged, synchronization gets worse, individual gears become hard or impossible to select. Often there is more behind it than simple wear.
After complete disassembly, the internal components are cleaned in an ultrasonic bath. Only in a properly cleaned state can wear, damage and other findings be assessed reliably. Each relevant part is then inspected systematically and documented. Damaged parts aren't just swapped — they're judged in the context of the whole gearbox.
- complete disassembly of the gearbox
- ultrasonic cleaning of the internal components
- systematic inspection of all relevant parts
- replacement of damaged and worn components
- sensible reinforcements and upgrades where needed
- transparent documentation with photos and videos
diagnosis
Signs of a faulty gearbox.
You don't need to know what exactly is wrong. A short description of the symptoms is enough — we'll work the rest out together.
process
How a VW T3 gearbox rebuild works.
- 01
- 02
First assessment
We get back to you and clarify the key points.
- 03
Delivery or shipping
We agree how the gearbox gets to us.
- 04
Disassembly & inspection
The gearbox is opened, inspected and documented.
- 05
Consultation
You get a clear assessment of what makes sense.
- 06
Rebuild & handover
Once approved, the gearbox is rebuilt and returned.
disassembly & inspection
Disassembly and inspection – €350
Before a reliable quotation for the rebuild can be prepared, the gearbox is completely disassembled. The internal components are cleaned in an ultrasonic bath and then assessed using a structured inspection protocol. This disassembly, cleaning and inspection is charged at €350.
- complete disassembly of the gearbox
- ultrasonic cleaning of the internal components
- systematic inspection based on our own inspection protocol
- documentation of relevant damage, with photos where applicable
- written, transparent findings report
- detailed quotation for the rebuild
- explanation of the observed damage and recommended work
transparency
No black box.
Every gearbox rebuild includes a detailed invoice as well as photographic documentation with an incoming condition report, a disassembly report and a measurement and setup report. This makes it clear in which condition the gearbox arrived, which work was carried out and how the critical settings were checked. The quality of the rebuild therefore remains verifiable for third parties even years later.

Gearbox rebuilds for T3 2WD and Syncro.
T3 2WD
Rebuilding classic T3 2WD gearboxes — from normal wear to problems with synchronization, bearings or gear wheels.
T3 Syncro
Syncro gearboxes are part of everyday work. Marek understands the demands of all-wheel drive, off-road use and loaded drivetrains from his own experience.
Specific gearbox types are discussed together based on your vehicle.
Standard on every gearbox
standard scope
What a proper gearbox rebuild includes.
The scope shown here is the fixed standard for every rebuild. Which components are actually used or worked on depends on the specific gearbox variant — the Syncro items are therefore standard on every Syncro gearbox.
Bearings & synchronizers
- Double taper roller bearings
- Deep groove ball bearings
- Differential taper roller bearings
- Synchronizer rings of 1st–4th resp. 2nd–5th gear
- Sliding sleeves
- Locking pieces
Additional on the Syncro
Syncro only- Deep groove ball bearing of the low range
- Deep groove ball bearing of the propshaft flange
- Check and free up the diff lock actuation
Reinforcement & sealing
- South African reinforcement plates
- Reinforcement plate on the bearing plate
- All seals
Measuring & adjustment
- Ring & pinion: offset, bearing preload, backlash
- Measure 3rd resp. 4th gear
- Measure reverse gear
- Measure G resp. 1st gear
modifications
More than just a rebuild.
Modifications and upgrades tailored to your T3.
Not every T3 is used the same way. Engine, tyre size, gear ratio and use case place different demands on the gearbox. Modifications and reinforcements are therefore never generic — they are planned to fit the vehicle and its intended use.
Adjusting the gear ratio
Matched to engine, tyre size and the planned area of use.
Improving known weak points
Where the findings call for it, early part revisions can be replaced with later or reinforced versions.
Reinforced special parts
For demanding requirements, reinforced components and selected special parts — including parts from the US — can be used.
Which measures make sense is discussed together after the inspection.

about marek
Grown out of the T3 scene.
Send it.Repair it.Repeat it.
Marek grew up with the VW T3 Syncro and drives his red bus every day as much as on off-road trips. Out of this driving and testing came a deep understanding of the gearbox over the years — its strengths, its weak points and what can be meaningfully improved.
Gearboxes leaving the workshop go straight back into use. What shows up there flows into the next rebuild. Driving, understanding, improving and testing come together as a closed loop.
That experience supports not only the rebuild of your gearbox, but also the identification of meaningful improvements for your T3.

faq
Frequently asked.
How much does a gearbox rebuild cost?+
An exact assessment is only possible after inspection. Once the gearbox is open and checked, we discuss the sensible work.
What does the €350 disassembly and inspection include?+
The gearbox is completely disassembled. The internal components are cleaned in an ultrasonic bath and then assessed using a structured inspection protocol. You receive the documented findings, damage photos where relevant, and a detailed quotation with explanations of the recommended work.
What does the standard rebuild scope cover?+
Depending on the gearbox type, the typical scope includes new bearings, synchronizer rings, sliding sleeves, locking pieces and seals, together with proven reinforcements and precise setup work. The final scope is defined after disassembly and inspection.
Are gear ratio changes or other modifications possible?+
Yes. Depending on engine, tyre size and intended use, gear ratio changes, reinforced parts or other upgrades can make sense. Possible measures are checked individually and discussed before they are implemented.
Can I ship my VW T3 gearbox for rebuilding?+
Yes, depending on the situation we can arrange delivery or shipping.
Does the gearbox have to be removed first?+
In most cases, the work concerns the gearbox itself. Just describe your vehicle and situation in the request.
Will I get feedback before major work?+
Yes. Issues and larger steps are explained and discussed before they happen.
Will I receive photos or videos?+
Yes. We document damage and key work steps with photos and videos.
Do you also do Syncro gearboxes?+
Yes, 2WD and Syncro are the focus.
What if I don't know what's broken?+
No problem. A short description of the symptoms is enough for the first contact.
