Transmission Fluid Diagnosis

By Mister Transmission

If you’ve recently started experiencing a transmission problem and wanted to check your transmission fluid level and condition, then this article could help you.

 

Transmission fluid is typically a clear reddish pink colour when new, and over the course of its life that colour can change quite a bit, meaning different things are occurring.

The first step is to make sure you’re actually checking your transmission fluid properly in order to get an accurate reading. When checking your vehicle’s transmission fluid, first consult your owner’s manual and follow their procedure for fluid level checking. Many different manufacturers require differing methods (ie – engine running, in park, etc). It’s best to use a white paper towel when checking and do at least 2-3 dips of the stick (wiping it down between dips) to ensure an accurate reading.

 
 

  • Good level and good condition: If your transmission fluid is to the full mark and a clean reddish pink colour, then the fluid is in good condition. You could still have a problem with your transmission, but it has not yet affected the fluid condition.
  • Low level and good condition: If your transmission fluid is low, there is a leak. Unlike your engine which can “consume” oil due to normal use, a transmission is a sealed unit. Have your transmission inspected as soon as possible to avoid internal damage.
  • Good level but brown colour: If your transmission fluid has a brownish tinge and a slightly burnt smell to it, then there is a problem. It could be just that the fluid is very old and no longer protecting the transmission’s internal components properly, or there are worn components causing excess friction and heat. Have your transmission inspected as soon as possible to avoid internal damage.
  • Good level but black colour: If your transmission fluid has a black colour and a burnt smell to it, there is an internal problem. This would be caused by excessive heat due to internal friction. Have your transmission inspected as soon as possible to avoid further damage.
  • High level and pink foamy appearance: If your transmission fluid is high and has a “strawberry milkshake” look to it, then there is a problem. This is usually caused by a failure in your radiator. The transmission fluid is cooled by a cooler built into your radiator. Sometimes when the radiator fails, engine coolant is allowed to cross-over into the transmission cooling tubes and contaminates the transmission fluid. Have your transmission inspected as soon as possible to avoid further damage.

It’s important to remember that due to the complexity of today’s computerized transmissions, that just because the transmission appears to be malfunctioning doesn’t mean the actual problem is in the transmission. Your vehicle’s computer gets signals from up to 32 separate sensors throughout the vehicle’s other systems and any one of these could be sending inaccurate or no information.

This is the second time I've visited Mr. Transmission. I originally contacted the location at jane and lawrence who advised they were swamped but put me in touch with someone at the Queensway location. Just as the previous experience, I have nothing but positive things to say. I would greatly recommend this location to anyone in need of automotive repairs.

Amazing service! Very friendly, and stayed in contact with me every step of the way. Couldn't beat the pricing and timing was second to none. Al and his staff are fantastic people. I would recommend Mr. Transmission on Essa Rd to anybody. In fact I already sent my boyfriend there and he is just as impressed with their service, professionalism, pricing and timing. Very happy I chose to go here!!

Very impressed by Cecil and his crew. Took my 2006 Jeep Cherokee in for fuel injector issues and had it running like a dream in no time. Finding a good mechanic that you can trust and won't take you to the cleaners is important to me. I'll get my jeep done here from now on. Shout out to Fab for taking care of my baby.
