When is it Necessary to Replace a Transmission

A big part of transmission repair is replacement. It is actually, literally, the biggest. Depending upon the problem your transmission is experiencing, there are a number of parts that could be replaced. And sometimes it’s not a “part” at all but rather the transmission fluid that requires replacing. However, sometimes the solution calls for the replacement of the entire transmission. But how do you know when that is the correct call? When is it necessary to replace an entire transmission?

Transmission repair

There are a lot of various factors that go into transmission repair and it’s not always the replacement of a part that is called for. However, replacement is often involved. As mentioned in the introduction, replacing your transmission fluid can help to solve a number of transmission problems, but certainly not all of them.

Often there is a part or parts that require replacement. For example, if there is a fluid leak, the transmission seals might have to be replaced. And there are a number of parts in your transmission that are accessible and can therefore be replaced without completely removing the transmission from the body of the vehicle. However, not all parts are accessible.

Transmission replacement

If the technicians working on your transmission determine that the part that is causing trouble is inaccessible while the transmission is within the body of your vehicle or if they cannot ascertain the cause of the problem while the transmission is within the body of the vehicle, then the transmission must be completely removed.

At this point, we’re talking a bigger deal of a repair. We’re talking about a possible transmission overhaul or replacement. A transmission overhaul is essentially a rebuilding of your transmission piece by piece, part by part. A replacement involves a wholesale change of transmissions. And a word to the wise: it is generally favorable to replace your transmission with a new one. Old transmissions have questionable histories and could be more bother than they’re worth.

When is it necessary?

Sometimes a problem has gone on for so long or has struck so severely that multiple parts of a transmission must be replaced. Or, determining the cause of the problem has become too difficult to pin down, and so the whole transmission needs to be replaced. As said earlier, this is not the most common type of repair, but it does happen. So how often is it necessary to replace a transmission?

The answer is, of course, “It depends”. With minimal care, you should reasonably expect your transmission to last around 160 000 kilometres. But that might not be as long as you think. Some estimates give the average driver about 24 000 kilometres a year, which means in less than seven years, the average driver will hit that 160 000 kilometre mark.

That’s why it is very important to take proper care of your transmission. Change the fluid regularly and bring it in for maintenance or repair as soon as you notice problems with your transmission to prevent them from worsening.

Robert Boem
What can I say about this place that hasn't been said already in the reviews.I took my 2019 nissan rogue in thinking it was a transmission problem.Giorgio and I went for a test drive and he honestly didn't think it was a tranny problem. He gave me a couple of recommendations to try before I bring it in for an appointment. Hard to find an honest mechanic these days. Thanks so much Giorgio I will definitely be back to see you if the problem doesn't get resolved.

Our old truck started making a loud noise near their shop. Glad it did. The staff were great. They put it up on the hoist and showed my husband the issues. We had some hiccups, it being an old vehicle. But the communication while they worked in it was great. We are very happy with their service. Will be back for future transmission issues with this old pickup.

Matthew Hoag
We had our transmission go on my partners birthday in Halifax. We live 2 hours away and the week was chaotic to say the least. Mandy and the team were amazing and not only found us a really good refurbished tranny for a great price, but also had the car done a week early which saved us rental car and insurance fees. Cannot recommend them enough. If you have tranny issues….GO TO THEM :)Matthew, Melissa, Maverick and Murphy
