What’s Involved in a Transmission Service?

Mister Transmission offers various types of transmission servicing, depending on your car’s needs. Here we explain the 5 most common transmission services.

A transmission service is part of your routine maintenance, just like replacing your engine oil. Here we’ve laid out the different types of transmission services we offer at Mister Transmission, including why they are important and what each service includes.

Automatic Transmission Fluid Exchange:

Transmission gears deliver power from the engine to the drive wheels, shifting automatically to provide the best power and efficiency for your driving speed. A special transmission fluid cools and lubricates the gears. Over time, this fluid degrades, and its lubricant qualities diminish. Changing the fluid at the correct intervals can help prevent premature wear and damage to the transmission.

This service includes;

Removal of the old transmission fluid and replacing it with new, clean fluid of the grade recommended by your vehicle manufacturer.

Automatic Transmission Drain and Fill:

Automatic transmission fluid lubricates, cools and cleans internal components of the transmission. It also helps to maintain the hydraulic pressure necessary for the transmission to function. The additives in the transmission fluid can be depleted over time.

This service includes;

  • removing the transmission fill/drain plug to remove the old automatic transmission fluid
  • reinstalling transmission fill/drain plug
  • refilling the transmission with new automatic transmission fluid to the proper level

Automatic Transmission Filter Replacement:

The automatic transmission filter helps remove dirt and contaminants from the automatic transmission fluid.

This service includes;

  • removing the transmission pan
  • removing the old transmission filter and replacing it with a new transmission filter
  • removing the old gasket material
  • replacing the pan gasket with a new gasket and reinstalling the pan
  • refilling the transmission with new automatic transmission fluid to the proper level

Automatic Transmission Fluid Exchange & Filter Replacement:

Automatic transmission fluid lubricates, cools and cleans internal components of the transmission. It also helps to maintain the hydraulic pressure necessary for the transmission to function. The additives in the transmission fluid can be depleted over time.

This service includes;

  • changing the fluid in the transmission system, including the torque converter and transmission cooler
  • removing the transmission pan
  • removing the old transmission filter and replacing it with a new transmission filter
  • removing the old gasket material
  • replacing the pan gasket with a new gasket and reinstalling the pan
  • refilling the transmission with new automatic transmission fluid to the proper level

Manual Transmission Service:

Manual transmission fluid provides lubrication to gears, bearings, shafts, and other internal components. Heat, pressure and friction can slowly breakdown the additives in the manual transmission fluid. In addition, small particles of metal may come off the gears as they wear and these metal particles can mix with the fluid. Fluids can also become contaminated with water.

This service includes;

  • draining or evacuating the old manual transmission fluid
  • filling the manual transmission fluid with the manufacturer’s recommended type and quantity of new fluid

The net result of all these services is to provide better lubrication, improve the holding ability of the friction components, and reduce heat. This means your transmission works better, longer. Therefor you are less likely to face a major transmission repair.
Mister Transmission offers all of these services, and will be happy to explain the details to you.

A complete transmission service should include:

  • removing and examining the sump or pan (where possible)
  • replacing or cleaning the screen or filter
  • cleaning the pan
  • reinstalling the pan with a new pan gasket

Customer Reviews
I took my vehicle to...
Mathieu Champagne
I took my vehicle to Mister Transmission to obtain a second opinion for a repair that Subaru City diagnosed (valve body replacement). Mister Transmission got me in for diagnosis as soon as I walked in the door. Their Shop Forman helped me out and took the vehicle for a road test and scanned for any codes and ended up diagnosing it with a totally different issue. He asked what Subaru City diagnosed and I told him CVT valve body replacement. He told me that wasn’t the issue and took the time to explain why the valve body replacement would not address the root cause of the issue. He explained that the actual repair required would be closer to $10k and was not worth the cost of the repair based on the mileage and age of my car. I really appreciate Mister Transmissions experience knowledge and honesty. It’s important to mention that the Subaru techs could not diagnose the issue in shop and had to send their findings to an online Subaru portal to obtain the diagnosis and I had to wait nearly 2 weeks for their diagnosis which was clearly incorrect and they charged me $190 to make an incorrect diagnosis. Mister Transmission, who are transmission specialists, were able to diagnose the issue in 10min with no cost to me. I recommend that everyone with transmission issues take their vehicles to Edmonton's Mister Transmission!
