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.

Mister Transmission

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.

Chris Elliston
I recently brought my car to Mr. Transmission to have a wheel bearing and axle shaft replaced, and I couldn’t be happier with the service. The price was very fair, and the work was done professionally and efficiently.What really stood out was the customer service — they even drove me home while my car was being worked on, which made the whole experience much more convenient. It’s not easy to find a mechanic you can truly trust, but these guys are honest, reliable, and clearly care about their customers.I would highly recommend bringing your vehicle here if you’re looking for a trustworthy and dependable mechanic shop.

Towed our Rav4 from the dealer who said we needed a new transmission to Mr.Transmission Exeter RD. London. Thinking we had to get a rebuild, Sanjay and his tech found it only needed a new axle and rear coupler so $000's less and so happy to have an honest shop who did not take advantage.

Thank you, Giorgio! An honest operator…I stopped by his Mister Transmission as a mechanic diagnosed a slow leak under my car as transmission fluid.Regardless of being tied up, Giorgio came out front to my Jeep Wrangler, crawled under, came back up, and said looks and smells like oil.He suggested the auto service shop next unit over. We went in and our explained the situation to the operator. I’m in good hands with the service shop now.Bottom line: Giorgio’s good turn, at no cost to me, quickly helped steered me in the right direction.
