Transmission overhaul is the process of maintaining, repairing and renewing a vehicle’s transmission system. Transmission is a mechanism that transfers engine power to the wheels and enables gear changing. Continuous use and wear over time can affect the performance of the transmission and require overhaul.

Transmission overhaul may consist of the following steps:

  • Evaluation: First, the condition and problems of the transmission are evaluated. Worn or damaged parts inside the transmission are detected and performance analysis is performed. The electronic components of the transmission can also be checked.
  • Replacement of Transmission Parts: Worn or damaged parts may need to be replaced. This may include parts such as the clutch pack, bearings, bearings, gears, seals and piston rings. Spare parts are usually obtained from the transmission manufacturer or authorized dealers.
  • Cleansing and Renewal: Transmission parts are cleaned and renewed when necessary. The cleaning process involves removing parts from dirt, oil and other debris. Refurbishment may include straightening parts, replacing seals, and other repairs.
  • Assembly and Adjustment: Transmission parts that have been revised or replaced are reassembled. At this stage, all components are placed correctly and necessary adjustments are made. Proper alignment and adjustment of the transmission ensures smooth gear changes.
  • Transmission Oil and Filter Change: During a transmission overhaul, it is important to change the transmission oil and filter. For a clean and properly functioning transmission, the recommended transmission oil should be used and changed regularly.
  • Test and Trial: Once the transmission overhaul is completed, it is tested to verify that the transmission is operating correctly and shifting gears smoothly.
