Check Transmission Fluid in Denver, CO

  • An automatic transmission depends on the transmission fluid for transferring engine power to the wheels, shifting gears, lubrication moving parts, and cooling down the transmission.
  • Properly checking the automatic transmission fluid is not as easy as one would think.
  • Vehicles use different procedures and getting a correct reading can be tricky. You need to know the proper conditions of the engine before checking the fluid level.  For instance: Car engine running, or Not?; Engine Cool or warm?
