Restoration of automatic and manual transmissions.

Over the years, the workshop has accumulated vast experience in the repair and restoration of various car gearboxes. In cooperation with many partners in Latvia and other European countries, we can update car gearboxes of any complexity. We offer it to our customers as a separate service or as part of a comprehensive car restoration. The workshop specialists will help organize transport and, if necessary, represent the client in customs procedures.

After dismantling the transmission, the gearbox is cleaned, disassembled and thoroughly inspected for defects. In addition, the light metal hydraulic transformer is dismantled and defective. After a gearbox defect, a list of replacement spare parts is drawn up and ordered. Depending on the design of the gearboxes and the wear of the individual parts, the range of replaceable parts may vary, but new clutch discs, rubber seals, crankcase gaskets and clutch brake are usually replaced.

As thorough and labor-intensive a process as disassembling a gearbox is assembling the gearbox.

A highly qualified car electrician performs all types of work that are subordinate to the car's electrical control, including diagnostics and repair of control units. This includes the repair of hydraulic transformers, testing the transmission by connecting diagnostic equipment.

Restoration of hydrotransformers.
Hydrotransformer - a complex, just like an automatic transmission, a mechanism that mainly serves to transfer torque from the engine to the transmission. Simply put, a hydraulic transformer is a hydraulic clutch. With the help of the Hydrotransformer, the torque on the output shaft is increased without interruption, while maintaining a constant engine speed.
The hydraulic transformer consists of: pump "wheel" (upper), turbine (lower), reactor (medium). Modern transmission HT also uses a piston, with the help of which HT is blocked, thus achieving fuel economy.
We receive all spare parts (bearings, friction discs, bushings, seals, sealing rings, etc.) necessary for the repair of the hydraulic transformer directly from the manufacturing plants.

Automatic transmission control system repair.
The first generation of automatic transmission control systems was fully hydraulic. Signals that were proportional to the car's speed and engine load affected the timing and quality of the shift. Depending on the relative proportions of these two signals, the gearbox was shifted accordingly. Thereafter, the hydraulics were used only as part of the control system performance. All other functions in modern cars are transferred to the control unit, which, receiving information from the signals of various sensors, processes and analyzes it and decides on the gearshift, while ensuring the appropriate transmission quality. In addition, the electronic control unit constantly monitors the operational validity of the system by storing in its memory the fault codes of the elements that occurred during operation. This function of the control unit is called self-diagnostics.
