Two new test benches are operational in the Tecnotrasmissioni testing department. The systems were designed and developed in collaboration with Apicom<\/strong> and customised to meet the company\u2019s specific technical and production requirements.<\/p>\n\n\n\n

The objective is clear: to reproduce as closely as possible the real operating conditions of a gearbox installed in a vehicle, whether a passenger car, commercial vehicle or truck.<\/p>\n\n\n\n

Compared with the previous test benches, the new systems provide greater testing capacity in terms of both rotational speed and braking power. This enables more thorough testing under conditions that more closely reflect the actual operation of the transmission.<\/p>\n\n\n\n

However, there is another, less visible factor that is particularly important for customers managing structured supplies. Every test performed on the new benches is linked to the unit\u2019s unique serial number<\/strong>, with a report generated automatically.<\/p>\n\n\n\n

The final test is no longer a stand-alone inspection: it becomes a recorded piece of data within the production history of that specific transmission.<\/p>\n\n\n\n

The two new test benches developed with Apicom for the final testing of gearboxes and transmission assemblies support dynamic testing, air leak testing and noise inspection at higher rotational speeds and braking power. They also increase the capacity of the testing department and link every test to the serial number of the individual unit.<\/p>\n\n\n\n

For the customer, this means more comprehensive testing, unit-level traceability and lower operational risk.<\/em><\/p>\n\n\n\n

What is a gearbox test bench and why is it a decisive stage in remanufacturing?<\/h2>\n\n\n\n

A gearbox test bench is a system that sets the transmission in motion, reproducing the operating conditions it will encounter once installed in the vehicle, and measures its response. This includes gear engagement, synchronisation, behaviour under braking load, sealing performance and noise levels.<\/p>\n\n\n\n

In an industrial remanufacturing process, testing is one of the final stages before packaging and shipment. It is the point at which all previous stages\u2014disassembly, washing, component selection and assembly according to manufacturer specifications\u2014are confirmed or disproved through measurable data.<\/p>\n\n\n\n

Without testing on a dedicated bench, the quality of a component remains a claim.<\/p>\n\n\n\n

With testing, it becomes a repeatable measurement performed on every individual unit.<\/p>\n\n\n\n

What changes compared with the previous test benches?<\/h2>\n\n\n\n

Higher rotational speed and braking power<\/h3>\n\n\n\n

The new Apicom systems extend the testing range across two fundamental parameters.<\/p>\n\n\n\n

A higher rotational speed makes it possible to verify the behaviour of the gearbox at speeds closer to those it will actually experience on the road.<\/p>\n\n\n\n

Greater braking power allows the transmission assembly to be tested under a load that more closely reflects real operating conditions, rather than simply running without load.<\/p>\n\n\n\n

For the customer, this means that anomalies occurring only under load can also be detected.<\/em><\/p>\n\n\n\n

Uncertain gear engagement, borderline synchronisation or noise appearing beyond a specific threshold can therefore emerge at the plant rather than in the workshop.<\/p>\n\n\n\n

Two testing lines<\/h3>\n\n\n\n

The introduction of two<\/strong> test benches, rather than just one, is not merely a quantitative improvement. It increases the production capacity of the testing department, reduces inspection times and provides greater flexibility when handling new product types and applications.<\/p>\n\n\n\n

For customers purchasing large volumes, testing capacity is a decisive factor in the management of structured supplies. Increasing testing capacity means supporting higher volumes while maintaining control over the finished product.<\/p>\n\n\n\n

Test benches customised to Tecnotrasmissioni\u2019s requirements<\/h3>\n\n\n\n

The systems were customised according to Tecnotrasmissioni\u2019s technical and production requirements. The same approach has already been applied outside the company\u2019s own facility: as part of the Stellantis Mirafiori Circular Economy Hub project<\/a>, Tecnotrasmissioni acted as technical partner and coordinated the development\u2014again together with Apicom\u2014of test benches for the Group\u2019s reconditioning departments.<\/p>\n\n\n\n

In other words, testing expertise is one of Tecnotrasmissioni\u2019s core competencies.<\/p>\n\n\n\n

What tests are performed on a transmission test bench?<\/h2>\n\n\n\n

Three main types of test can be carried out on the new benches.<\/p>\n\n\n\n

1. Dynamic gearbox testing<\/h3>\n\n\n\n

This is the most comprehensive inspection and includes:<\/p>\n\n\n\n
