Gearbox Overhaul Process

  1. Disassembly: This step involves removing the transmission from the vehicle and then disassembling it. In the case of ZF transmissions and PDK transmissions, special tools are required to disassemble them. For CVT transmissions, extra care must be taken during disassembly as the belt or chain is delicate and can easily be damaged. For AT transmissions, the torque converter and oil pump are usually removed first before disassembling the transmission.
  2. Inspection: Each part of the transmission is inspected to determine its condition. This includes the gears, bearings, clutches, seals, and other internal components. In some cases, specialized equipment like a magnetic particle inspection machine may be used to detect cracks or other defects that cannot be seen by the naked eye.
  3. Cleaning: Thorough cleaning of the internal components of the transmission is crucial to prevent any debris or contaminants from causing further damage to the transmission. Specialized cleaning solutions are used to clean the parts, and in some cases, an ultrasonic cleaner may be used to remove stubborn dirt and grime.
  4. Reassembly: This step involves reassembling the transmission with all new parts installed. Careful attention must be given to torque specifications and the proper alignment of gears and other components. In the case of CVT transmissions, the belt or chain must be properly tensioned and aligned. In the case of PDK transmissions, the clutch system must be properly calibrated.
  5. Testing: The final step is to test the transmission to ensure it is functioning correctly. This involves testing the transmission on a test bench or in the vehicle to ensure it shifts properly and operates as intended. In some cases, additional adjustments may need to be made to ensure proper shifting and smooth operation.

Gearbox overhauls are a complex process that requires careful attention to detail and expertise, and very specialized knowledge and skills. It is essential to trust the work to a qualified and experienced technician to ensure the transmission is overhauled correctly and functions as intended.
