A line of reconditioned transmissions for the Stellantis Group:
the Tecnotrasmissioni industrial model

For a major automotive group, managing transmission spare parts across a broad vehicle fleet is a matter of supply continuity, technical control and responsiveness, not just logistics.

In this context, the new component is not always the most efficient or most readily available solution. Production discontinuity, products returned under warranty, models still on the road but no longer in production: these are critical issues that the supply of new components alone cannot cover continuously.

This is where the collaboration between Tecnotrasmissioni and the Fiat Group – later FCA and now Stellantis – began at the end of the 1990s, with the aim of developing a line of reconditioned transmissions to support the after-sales supply chain.

In summary: a collaboration that started with the Fiat Group, continued with FCA and is now associated with Stellantis, focused on the development of a line of reconditioned transmissions. A collaboration that has led to the management of over 7,000 gearboxes and transmission units per year and has helped support supply continuity even for out-of-production models, with technical control on every unit and lower operational risk across the supply chain.

The challenge: ensuring continuity across a broad and diversified vehicle fleet

The management of transmission spare parts must respond to different and often simultaneous needs and ensure structured supply continuity as an alternative to new components.

Maintaining supply for models already present in the circulating fleet

Many vehicles remain on the road well beyond the end of production of the original component. Ensuring spare parts availability for these models means protecting the continuity of after-sales service over time.

Managing products returned under warranty and defective components

Warranty returns and components requiring replacement need a clear technical process to be assessed, recovered or replaced while keeping the operational flow continuous.

Reducing dependence on new components that are not always available

Production discontinuity and supply issues affecting new components can slow down the entire chain. A reliable reconditioned line reduces this dependence, which means, for the supply chain, greater predictability in supply planning.

Making the most of components that are still technically recoverable

A significant proportion of used units still has recovery potential. Reintroducing them into the cycle through a controlled process avoids waste and optimizes the use of resources.

The approach: from technical analysis to application selection

The collaboration started with an assessment of the products suitable for inclusion in a structured offer of reconditioned automotive components.

The technical and industrial analysis carried out on each product family made it possible to compare several factors:

technical characteristics of the component;
availability of starting units;
frequency of demand in the aftermarket;
supply criticalities affecting the new component;
volume of warranty returns;
recovery potential of the component;
industrial sustainability of the process;
operational convenience for the after-sales supply chain.

Based on these parameters, we identified the transmissions best suited to the reconditioned line, building a more efficient offer for the aftermarket network and one more closely aligned with actual market demand.

The solution: a structured industrial process

Each selected transmission is handled through a structured and repeatable industrial process – disassembly, analysis, component selection, replacement of parts, assembly and functional testing – applied to the families of gearboxes and transmission units intended for the reconditioned line, including:

C510 / C526
C510 / C513
C514
C523 / MG
C537 / MLGU 5-speed
C544 / M32
C546 / M40
C547 / MLGU 6-speed

The collaboration reached significant annual volumes, exceeding 7,000 units per year across gearboxes and transmission units. This result was made possible by an organized production model, capable of ensuring repeatability of the result, operational continuity and technical control on every single unit processed, providing the customer with controlled quality standards and predictable supply times even at scale.

The evolution of standards and IATF 16949 certification

Working with a leading automotive group made it possible to progressively strengthen the quality system, ultimately achieving IATF 16949 certification, the international standard specific to the automotive sector.

This path consolidated an approach based on:

process control;
complete traceability;
prevention of non-conformities;
structured supplier management;
continuous improvement;
alignment with the needs of corporate and OEM customers.

The certification enabled Tecnotrasmissioni to become a qualified industrial partner for structured automotive programs.

For a vehicle manufacturer, this means working with a supplier verified by independent third-party bodies, with documented and traceable processes throughout the supply chain and in strict compliance with manufacturers’ technical requirements.

The value of the collaboration: a replicable model

Through the collaboration with the Stellantis Group, Tecnotrasmissioni integrated into a complex automotive supply chain, turning an operational need into a structured, controlled and scalable program.

For the customer, this brought concrete benefits: supply continuity even for out-of-production models, reduced dependence on new components, more structured management of volumes and warranty returns, cost optimization through the recovery of components that are still technically valid and a reduction of operational risk across the entire after-sales supply chain, in full alignment with the principles of the circular economy.

Frequently asked questions – FAQ

Can Tecnotrasmissioni manage large-scale supplies for vehicle manufacturers and OEMs?

Yes. The industrialized and standardized production model makes it possible to manage large-scale supplies while maintaining controlled quality standards and predictable delivery times. The collaboration with the Stellantis Group, with annual volumes exceeding 7,000 gearboxes and transmission units, is a concrete example.

Does Tecnotrasmissioni offer dedicated regeneration programs?

Yes. In addition to supplying individual components, Tecnotrasmissioni develops dedicated regeneration programs for automotive companies, structured distributors and corporate organizations, covering gearboxes, differentials, transfer cases and complete transmissions. This operating model is built around the specific needs of the customer: component type, volumes, supply frequency, technical standards, traceability and delivery times.

Rely on an industrial partner for your aftermarket programs

Managing transmissions within a complex automotive supply chain requires continuity, technical control and responsiveness at scale. This is exactly what Tecnotrasmissioni has been building for over 25 years as an industrial partner to supply chain operators and vehicle manufacturers.
