Where is the transmission oil port located?

[DelRemington]

Transmission oil ports are located on the transmission housing of the vehicle. There are two bolts: the upper one serves as the oil filling port, while the lower one is the oil drain port - this applies to manual transmissions. For automatic transmissions, there are one or two bolts on the lower housing of the transmission, with the larger bolt being the oil drain port and the smaller one the oil filling port. Transmission fluid is crucial for vehicles and requires regular replacement, typically every two years or every 60,000 to 80,000 kilometers. However, this varies depending on the type of transmission, as vehicles have either automatic or manual transmissions. When replacing automatic transmission fluid, the process involves removing the transmission oil pan screw to drain the old fluid before adding new fluid, which only replaces about 70% of the old fluid. For a complete replacement, it's necessary to visit a specialized service center that uses a circulation machine for oil change, achieving over 90% replacement.
