How Much Does Flushing a Transmission Cost?

The automatic or manual transmission gears are responsible for delivering power to the wheels.The lubricants are essential to protect the bearings, gears, and shaft from wear and tear. 

Fluid change cannot completely drain out the old oil in the system. At most, fluid change can only change about 20%-40% of the total volume. It is not also efficient to remove grime, debris, and sludge that built up over time in the system. Such substances can block the channels and valves that hinder the normal flow of the fluid in the transmission. If left alone, the transmission could suffer from internal damages and could reduce its lifespan.

The debris can also deteriorate the performance of the vehicle and furthermore, can result in complication while driving. Cars Direct provided a list of signs that represent the presence of debris in the transmission.

  • Strange noises while shifting gears
  • Improper respond of gears
  • Slipping gears
  • Surging of the vehicle
  • Delay in the vehicle movement

Meanwhile, flushing the transmission can drain out all the old oil in the system. The efficiency of flushing out the oil is about 90% – 95%. 

To assess the applicability of the flushing procedure, diagnose and check-up of the transmission are a must. The car makers also provide vital information regarding the necessity and applicability of flushing written on the car’s maintenance manual. Service providers also recommend performing transmission flush for every 30,000 mileage reached or 2 years.

Factors Affecting the Transmission Flush Price

  • Type of vehicle

The carmaker, model and year of the vehicle have a huge impact on the quote. Latest and high mileage cars usually cost more due to the complexity of the procedures. In some instances, old models can also yield higher cost depending on the supply of adequate spare parts. Automatic transmissions can also increase the price because of the involvement of various complicated moving parts.

  • Location

The location of the shop can directly impact the price due to the cost of labor. Cities with a higher cost of living usually have higher labor rates. Shops usually include the additional cost for their service.

  • Type of Shop

Quick lube shops provide cheaper flushing services in comparison to the dealers. Even so, it is important to find a reliable and competent provider since transmission flush is a delicate procedure. But the experience and specialty of the staff in the service center of dealers should be factored in the decision. Also, parts and equipment are much more available in service centers.

  • Type of Flush Machine

There are two types of machines that are usually being used. The pump inlet flush machine increases the transmission flush price because the machine operates with pumps to change the fluid in the system. Meanwhile, a cooler line flush machine which is usually used by quick lube shops is cheaper to operate since it does not involve any electronic.

  • Type and Amount of Fluid

The type of fluid to be used for the vehicle can significantly change the cost of the service. Conventional oil or petroleum-based transmission fluid is much cheaper and effective. However, synthetic oil can last longer than petroleum-based fluids and improves the overall performance of the transmission.

The volume required to change the oil completely is the capacity plus the amount of fresh fluid to flush out the old oil in the system. Pump inlet flush machine usually uses 20 quarts of fluid to flush out the 15 quarts of the old fluid.
