Torque Converter Remanufacturing

Torque Converter Remanufacturing

The torque converter is one of the most critical components in an automatic transmission: it transfers and multiplies engine torque, adapting seamlessly to load and driving conditions - and in most modern units it also carries a lock-up clutch that works as hard as any clutch in the gearbox.

Wear of the lock-up clutch, bearings, one-way clutch, splines or other internal elements can cause vibration, noise, overheating or incorrect torque transfer - and when friction or metal components break down, the contamination can reach the valve body and the cooling system. Professional remanufacturing restores the unit according to the applicable technical requirements at a fraction of the cost of a new one - and at MID Auto it happens on a production line built exclusively for this job.

REMANUFACTURING PROCESS

We follow a precise, fully in-house process that restores torque converters according to the applicable technical requirements and control measurements. In 2013 we equipped the Varna workshop with a complete 7-station production line dedicated exclusively to torque converter remanufacturing - an investment in controlled quality and fast turnaround.

1/
Initial Inspection & Diagnostics
  • Inspection of the converter housing and welds, assessment of clutch plate and seal wear, checks for damage of the hard parts, clearance measurements, and checks for visible signs of overheating, distortion or contamination. The final assessment is made after opening the converter.
2/
Precision Cutting & Opening
  • Converters are factory-sealed by welds: specialized equipment separates the housing cleanly, preserving alignment and critical surfaces.
3/
Cleaning & Component Preparation
  • All internal parts are cleaned in industrial washers, with blasting where needed - contaminated fluid from the old failure does not survive the process.
4/
Replacement of Worn Components
  • The lock-up friction lining, bearings and hubs, seals and O-rings, and damaged turbine or stator elements are replaced according to the design and condition of the unit - all from our own import stock.
5/
Assembly
  • Components aligned to the applicable tolerances; high-precision welding restores structural integrity.
6/
Balancing & Quality Control
  • Every applicable unit is balanced per the established procedure to control residual imbalance, followed by a pressure leak test.
7/
Final Inspection & Packaging
  • A last check before the unit is securely packed for installation or shipping.

DIRECT IMPORTER

MID Auto is a direct importer of torque converter components from globally recognized manufacturers. We rely on:

Premium friction materials

High-quality friction materials

lock-up clutch linings selected for long life and smooth engagement.

FAQ

Most units are ready in 1-3 working days depending on complexity and parts availability - the dedicated torque converter repair line is what makes that speed repeatable.

In many cases yes: the unit is restored according to the applicable technical requirements with quality friction materials and renewed internals, at a fraction of the price of a new unit - while reusing the housing, which is also the environmentally sensible choice.

Shudder or vibration while driving, slipping, overheating, delayed acceleration, whining or rattling, and dark fluid with metal particles. These symptoms alone do not prove a converter failure - professional diagnostics confirms the cause before any disassembly.

Yes - remanufactured converters include a 6-month commercial warranty against defects in materials and workmanship, subject to our Warranty Policy. Converters remanufactured within a complete transmission repair in our Varna workshop are covered by the repair’s 12-month warranty instead. The warranty requires installation by a qualified specialist, the root cause of the failure addressed, an inspected / cleaned cooler circuit and fresh fluid of the correct specification and level - a converter fed with old, contaminated fluid inherits the previous failure.

Yes - we work with B2B customers, workshops and private owners across Europe and beyond. Send us the unit, and after remanufacturing and quality checks we handle the return shipment.
