Everything You Need to Know About Transmission Fluid Changes

Transmission fluid is (almost literally) the lifeblood of the transmission. An automatic transmission simply won’t work without transmission fluid. Now, you would have to have a very large leak to have absolutely no fluid in your transmission. However, you still need to have the right level and the right quality of transmission fluid or else you’re inviting transmission problems to happen. To have your transmission in perfect working order, you might require a transmission fluid change.

Transmission Fluid

Transmission fluid works as a lubricant and it is optimized for the functions of the transmission. These functions include valve operation, brake band friction, and the torque converter. Transmission fluid is required in all automatic transmissions. Some manual transmissions also use transmission fluid, but some use engine oil or gear oil.

Transmission Fluid Problems

Not all transmissions are the same; not even all automatic transmissions. But all transmissions experience wear and tear that can cause debris to collect in the fluid. Furthermore, there can be problems within transmissions that cause the fluid to be damaged or degraded, and this in turn can cause further problems.

And then there are leaks. Any transmission can fall foul of a leak. The key sign of a leak is a patch of reddish liquid that has collected underneath your vehicle as it is parked. Leaks have to be patched and the lost fluid needs to be topped up.

Symptoms of using Poor Quality Transmission Fluid

If the fluid in your transmission is lacking in either quantity or quality, you will begin to notice symptoms in how your transmission operates. You may experience a temporary delay while shifting gears. Your transmission may take a moment to register the gear shift. Your transmission might also grind or clunk when you shift. Alternately, your transmission might slip from one gear into another (usually neutral) which can be very dangerous. And without enough fluid, your transmission can become overheated.

Transmission Fluid Changes

You should periodically check your transmission levels using your dipstick. Sometimes you can lose some fluid without experiencing a leak. In this case, you can top of the transmission fluid yourself or you can bring it into a transmission shop for a top up.

Transmission fluid changes can sometimes be a bit more complicated. Typically a fluid change is required when the fluid has become degraded or burned. You might be able to tell this yourself. Normally, transmission fluid is translucent with a reddish hue. If your fluid is opaque and/or has a foul smell to it, it is probably damaged. Also, transmission fluid can pick up too much impure matter from wear and tear within your engine. If this is the case, it has probably been detected by a technician during a pan examination.

How Transmission Fluid Changes Work

You might be able to do a transmission fluid change on your own, depending on the type of transmission you have. But sometimes it is necessary (and always a lot easier) to bring it in to a transmission shop. Here, technicians can flush out the bad transmission fluid and change it with new, better quality fluid.

Had my transmission rebuilt and these guys did an amazing job! The quality of work exceeded my expectations. Thanks to Gus for explaining procedures, letting me know the labour cost upfront and what to expect in terms of cost when the transmission is taken apart. I commended Mr. Transmission for this; rebuilding a transmission is costly!

Susan Reynolds
Last week, on our way to a family reunion, we experienced trouble with the transmission and fluid leaking from rusty lines. We stopped at Mr. Transmission and experienced the best customer service! They worked hard to find the parts required and repaired our vehicle in a timely and cost effective manner! Kudos to the Mr. Transmission team! They could give lessons in customer service! Just an aside as we were struggling to move forward and find out what was even wrong with the vehicle, we pulled into Green & Ross. A person came out and expressed their concern that we were blocking their available and empty parking spots. They didn't seem to be interested in assisting us which is when we quickly decided to move on and we googled Mr. Transmission - a fantastic choice!

Antonio Pena
I was having issues with rough driving and my car not wanting to go into AWD. I brought it to indi shops and couldn't find the issue. I called up Mr transmission and from the very first call to the last interaction I was very happy and impressed with the service and quality job they did. They were able to find the issue and fix it, no issues. Replaced my front left cv axle and I was on my way. After the fix I was now able to notice some smaller vibrations at higher speeds. I wanted to make sure it was not a problem. They were able to check everything for me to make sure it was nothing to do with the work or part they replaced. They confirmed it wasn't and recommended a fix. They were able to help me out again! Long story short I will be recommending everyone I know to this location. They have a great group of people working there!
