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.

We were travelling down to Toronto to catch a flight and ran into transmission issues. Called about 5 min past closing expecting to leave a message, but Aki answered and got everything arranged to be repaired while we were away on holidays. Returned to a working vehicle and drove home safe. Communication was constant and very clear. Top notch service. Thanks Aki and team

May 2026. Took my 2007 Pontiac Solstice here for Transmission Service. This Business is like a breath of fresh air. They are experts at what they do, and were familiar with all the quirks of a Pontiac Solstice. They explained to me what they going to do, and did it in a timely fashion. Thank you for taking care of my “Baby”. I appreciate your service and the care and pride you show while you do it! Now I know where to go with any future problems with a transmission!

Mike MacCluskey
We own a Nissan Pathfinder with the dredded CVT transmissions that self destruct. Through my research there are only 2 choices in Metro. The Nissan Dealership at a premium price point, and this location of Mister Transmission for a reasonable price point. My experience with the knowledgeable staff, and level of professionalism was outstanding! They made me feel at home and answered all of my questions. Highly recommend!
