What is the Manual Transmission Fluid all about?

Manual Transmission Fluid provides lubrication and protection to gears, shafts, and bearings inside the manual transmission.

Keep in mind:

  • Most manufacturers advise that manual transmission fluid needs to be replaced every 30,000 to 60,000 miles.
  • You need to consider if your vehicle is performing heavy-duty work like towing or lots of stop and go driving.
  • In cases where vehicles are used more heavily, a technician may recommend that fluid be replaced every 15,000 miles.

How it's done:

  • Locate the fill plug and drain plug for manual transmission
  • Place an oil drip pan to collect old fluid below the drain plug
  • Remove the fill plug and remove the drain plug allowing old fluid to drain
  • Reinstall the drain plug using a torque wrench
  • Using a fluid pump, installing new transmission fluid into the fill hole
  • Reinstall the fill plug

Our recommendation:

Rather than waiting for your vehicle to hit the 30,000 mile mark, you may want to consider how much work your vehicle is having to perform because low level or poor quality of transmission fluid can lead to gear slippage and even transmission failure.

What common symptoms indicate you may need to service Manual Transmission Fluid?

  • Harsh shifting into gear, not as smooth
  • Excessive heat felt through shifter or burnt smell
  • Grinding noises when shifting
  • Humming noises coming from the shifter area or underneath while driving
