1) What does the gearbox PN/OEM mean and where can I find it?

The factory part number on the gearbox plate or in the catalogue; after it, the identical variant is selected for the VIN and controllers.

2) What is the difference between "automatic", "SMG" and "Tiptronic"?

Automatic (AT) has a converter, SMG is an automated manual, Tiptronic is a VAG automatic with manual mode - different controllers and ATF.

3) Does the " Passat B5 FL 130KM gearbox " fit another 1.9 TDI?

Only with matching gearbox code and gear ratios; different driveshafts and housings may preclude plug-in installation.

4) " Mini Cooper R50 gearbox " – what to check before buying?

Shaft diameters, selector type and part number; year differences are key to fitment.

5) " PK6 gearbox / Opel Vivaro" is making noise - replace or buy a used one?

When rebuild costs are high, a used PK6 with the correct PN and gear ratios can be economical.

6) Automatic " Audi A6 C6 Tiptronic " – will any gearbox work?

No; quattro and FWD have different outputs/flanges and the TCU must match the vehicle's ECU.

7) Will Global Parts select a complete kit based on the VIN (AT/MT/transfer)?

Yes – support includes the gearbox, accessories (converter/cooler/harness) and indication of the correct ATF/oil; installation and adaptations recommended at the service center.

Used gearbox – when is it worth it and what should you remember?

The gearbox is a key component of any vehicle, responsible for transferring power from the engine to the wheels. A gearbox failure can effectively immobilize the vehicle, and repair costs can be significant. In such a situation, many drivers consider purchasing a used gearbox. Is this a cost-effective solution? What should you consider when choosing? In this article, we'll explore these issues, comparing manual and automatic transmissions, discussing compatibility issues, and analyzing the cost-effectiveness of remanufacturing versus purchasing a used part. .

Manual vs. Automatic Transmission – Key Differences

When deciding to buy a used gearbox, the first step is to determine which type we're dealing with. Manual and automatic transmissions differ in design, operation, and operating and repair costs.

Manual gearbox

Manual gearboxes They are characterized by a simpler design, which translates into lower repair and maintenance costs. They are also more durable and less prone to breakdowns compared to automatic transmissions. When purchasing a used manual transmission, it's worth paying attention to:

Synchronizer operation : If the gears engage smoothly and do not "jump" while driving, this indicates that the synchronizers are in good condition.
Bearing Condition : Disturbing noises when shifting gears may indicate bearing wear.
Tightness : The absence of oil leaks is a good sign that the gearbox is tight. It's also worth remembering that manual transmissions are cheaper to repair and service than their automatic counterparts.

Automatic gearbox

Automatic gearboxes They offer greater driving comfort, especially in city traffic, eliminating the need for manual gear changes. However, their design is more complex, resulting in higher repair and maintenance costs. When purchasing a used automatic transmission, pay attention to:

Mileage and service history : Regular ATF (Automatic Transmission Fluid) changes are crucial to the longevity of your automatic transmission.
Performance during a test drive : Smooth gear changes without jerks or delays indicate good condition of the gearbox.
Controller Compatibility : Make sure the correct controller is included or that your current one will be compatible with the new transmission. It's also important to remember that automatic transmissions are more mechanically complex, which can result in higher repair costs compared to manual transmissions.

Component compatibility – what to pay attention to?

When replacing the gearbox It's crucial to ensure the new component's compatibility with the rest of the vehicle. For manual transmissions, check:

Gear Ratios : Different car models may have different gear ratios, which affects performance and fuel consumption.
Gearbox housing : Some car models came with several gearbox variants that differ in housing and mounting points. For automatic transmissions it is important to:
Controller Compatibility : The gearbox controller must be compatible with the vehicle's on-board computer.
ATF Type : Make sure the new transmission requires the same type of oil as the old one.

Regeneration and purchase of a used gearbox – profitability analysis

In the event of a gearbox failure Drivers face a dilemma: rebuild their current car or buy a used one? Both solutions have their advantages and disadvantages.

Gearbox regeneration

Reconditioning involves disassembling the gearbox, replacing worn components, and reassembling and testing it. The advantages of this solution include:

Certainty about technical condition : All worn gearbox parts are replaced with new ones.
Warranty : Professional workshops provide a warranty for the service performed.

Buying a used gearbox

An alternative to regeneration is to buy a used gearbox. This solution often proves more economical, especially when the cost of reconditioning exceeds the vehicle's value. When choosing a used gearbox, it's worth considering:

Warranty : Reputable sellers provide warranties for the parts they sell, which provides assurance of their quality and technical condition.
Compatibility : Make sure the gearbox fits your car model, taking into account the year of manufacture, engine version and other technical specifications.

Definitions and parameters – gearbox families, markings, fit (VIN/OEM/PN)

BMW E60 automatic transmission – types belong to different manufacturer families (e.g., ZF/GM), recognized by the type designation (e.g., "6-speed," "SMG," "AT"), the data plate, and the PN/OEM number ; therefore, in practice, the terms "bmw e60 automatic transmission types" / "bmw e60 automatic transmission" / "bmw automatic transmission" should always be combined with the VIN. The Audi A6 C6 Tiptronic transmission / Audi automatic transmission works with a dedicated controller and a specific ATF (e.g., VAG spec for 6-/7-speeds). The Passat B5 gearbox / Passat B6 gearbox / Passat B5 FL 130KM gearbox differs in gear ratios and housing – correct fitment requires matching the gearbox code. The Mini gearbox / Mini Cooper gearbox / Mini Cooper R50 gearbox has different driveshaft diameters and a different selector than in newer generations; the PN/OEM number also applies here. resolves ambiguities.

Fitting procedure – step by step (manual/automatic/transfer case)

Step 1 – Identification by VIN and code : write down the VIN, engine code and gearbox code (e.g. gearbox label, mechatronics cover). In 4×4 vehicles, also the transfer case code (e.g. BMW X3 E83 transfer case ). Step 2 – Technical parameters : number of gears (5/6/7), control type (cables/electronics), clutch type (dual mass/converter), ATF/oil standard (e.g. manufacturer’s spec), flange/axle diameters, speed sensors (plug type). Step 3 – Installation and integration : automatic transmission requires TCU (control unit) and wiring harness compatibility; manual transmission – disc and slave cylinder diameters; PK6 transmission / Opel Vivaro transmission (6-speed family) has different selector and paddle lengths – PN determines. Sprinter 906 transmission / BMW X3 E83 automatic transmission – gearbox adaptation/learning recommended after installation. Work on the drivetrain and controllers should be performed by a mechanic/service center.

Practical comparison – when a used gearbox has an advantage (cost/fit)

Used gearbox It works well when cost savings and compatibility without assembly "sculpture" are important: a complete set of accessories (converter, mechatronics, sensors) "comes to life" faster after software adaptation than a mixture of new replacements. In VAG projects ( Tiptronic gearbox Audi A6 C6, automatic gearbox Audi A6 quattro ) and BMW ( SMG E60 gearbox / sports gearbox ) maintaining the original gear ratios and shift calibration provides a predictable driving experience. Global Parts helps you select the "plug-in" unit by VIN and the accessories (oil cooler, hoses) required for the swap.
