GTE Engineering offers professional rebuilding and restoration services for the hydraulic transmission shift actuator used in Lamborghini E-Gear and Audi R-Tronic transmissions.

This critical hydraulic actuator assembly is responsible for gear selection and shift engagement within the Graziano automated manual transmission system. Internal wear, contamination, leaking seals, faulty shift valves, pressure loss, and worn actuator components can lead to gear engagement faults, shifting issues, neutral selection errors, and transmission warning messages. Sensors are tested but not included. The electrovalves are tested and calibrated. If we find these parts to be damaged will inform the customer of the cost of the parts. 

Each actuator is completely disassembled, cleaned, inspected, measured, rebuilt, reassembled, and function tested to ISO engineering standards.
