How Do I Know If My Transmission Needs To Be Replaced?

If you can avoid it, you really do not want to replace your transmission. Transmission replacement is not cheap. However, sometimes it is your best option. But how do you know if your transmission needs to be replaced?

Transmission problems can manifest in dozens of ways. It is always sensible to keep your eye (and ear) out for possible problems so you can spot them before they become so big that they require you to replace your transmission.

Transmissions are intricate pieces of machinery. In fact, they are dozens of different parts of machinery all working in congruence with one another. This means there is a lot that can go wrong. But like with most things, transmission problems start off small before they get big. Only big problems require transmission replacement so it would be wise to nip small problems in the bud.

See patches of red liquid underneath your car as you pull out of your driveway? That is transmission fluid and it means you have a leak. Top up your fluid and visit a transmission shop as soon as possible to avoid further damage. Low levels of transmission fluid can do enough damage that you may need to replace your transmission. Furthermore, listen for funny noises —whirring, humming, buzzing, grinding, etc.— which are symptomatic of transmission problems. Slipping out of gear or difficulty shifting gears are also symptoms of transmission problems.

Do any of these above transmission problems mean that your transmission needs to be replaced?

Not necessarily. Many of these problems can be solved with relatively minor fixes. Sometimes you just need your transmission fluid flushed out and replaced. Other times, the problem part or parts are accessible while the transmission remains in the chassis, meaning they can be swapped out rather easily.

But what if a transmission problem can’t be fixed with new transmission fluid or replacing an accessible part? Does it have to be replaced then?

Maybe. If the transmission techs need to remove the transmission from the body of the vehicle, then you are looking at a more involved repair. Sometimes you can get lucky and the techs will be able to narrow the problem down to one or two components that can be replaced once the transmission is removed. However, some transmissions are so damaged that they need to be replaced altogether. Other times, transmissions can be overhauled, in which each component is removed, inspected, and replaced.

At Mister Transmission, we often recommend transmission overhauls, replacing one with another transmission of unknown provenance. But every case is different and you can’t know if replacement is necessary right away. To learn more about transmission replacement, please contact us.

I had a problem with...
Ann O'Regan
I had a problem with my 2012 Honda Civic trani with 625km. I took it to Honda service for a diagnosis and it was confirmed to be the transmission.But repairs and new/used parts would be way too costly. For about 6 months knowing it could of been an engine mount issue due to strong vibration, a bit of gear slipping and some jerking while increasing speed...so I brought my car to Mr. Transmission in Pickering and was welcomed by a such a nice gentleman Chris, the owner Ken's son when I told him my issue. Right away we went for a test drive on the highway returned and did confirm and explained in detailed as a second opinion that I needed a new used trani and definitely a torq converter...he located a trani for me at a very great price with low kms and I chose to get the work done with him. A date was set when the trani was delivered. I dropped off my vehicle 2 days later at 9am. I rented a car at Enterprise Car Rental that morning as they were in the same automotive plaza. To my surprise, by 3pm, I received a call from Chris that the work for the transmission being replaced was complete in a very timely manner. I was ecstatic as I didn't expect to be done till the next day. I returned the rental and picked up my car. It's been running excellent like a brand new car as I do a lot of mileage weekly on my vehicle. I could not have been more happy about the whole experience with Mr.Transmission in Pickering with Chris. His customer hospitality, honesty, caring and very reasonable pricing made it all worth it explaining every detail what had to be done delivered professionalism and expertise at its best. I highly absolutely recommend this place to cater to all your transmission needs from a truly satisfied customer!!!!

Clinton Slaunwhite
Awesome place to go for any automotive needs, they only do the work required, and don’t push anything on you… Very honest . First, early diagnosis by looking at it, they believed it to be a damaged radiator, but after taking it apart, realized it was just a seal that needed to be replaced… They easily could’ve just changed the radiator and nobody would’ve known, instead they just replaced the seal and cut my Original quote by $600+ Highly recommend
