Replacing and Overhauling Transmissions

Replacing and Overhauling Transmissions

Many transmission problems can be fixed with relatively minor repairs. Highly skilled technicians are trained to spot problems by surveying a transmission and figuring out where the trouble is. Many of the common problem spots in transmissions are accessible without having to remove the transmission from the vehicle. Unfortunately, not all transmission repairs are so simple. In more serious situations, transmissions might need to be removed from the vehicle in order to repair it properly. In such cases of major transmission repair, we are often dealing with the replacement and overhaul of a transmission.

Transmission Maintenance

As a point of order, it is important to note the significance of transmission maintenance. Basic and routine transmission maintenance is your best tool to avoid major transmission repairs such as replacements and overhauls. But it can be hard to stay on top of transmission maintenance, and we all make mistakes. And sometimes you can do everything right and your transmission will still require a major repair.

Transmission Repair

As mentioned in the introduction, many transmission repairs do not require replacement and overhaul. Transmission repair is often a relatively quick process. Sometimes it requires the repair of a straightforward mechanical problem. Other times, there is a computer issue, which can be more difficult, but does not necessarily equal the seriousness of a task such as replacement and overhaul.

But not even well-trained and highly skilled technicians can repair every transmission problem without the transmission needing to be removed from the body of the vehicle. If you drive your vehicle for long enough, it will become likely that an overhaul becomes necessary at some point. While replacement and overhaul is a more involved process than many transmission repairs, it is not an automatic catastrophe by any means.

Overhaul And Replacement

When the time comes that your transmission needs an overhaul, you have two options from which to choose. The first is to remove your existing transmission and overhaul it, then put the rebuilt unit back in your car. The second option is to replace your existing unit with another unit that has already been rebuilt or re-manufactured.

In many, indeed, probably the majority of situations, replacing your transmission with a used one is unlikely to be your best option. Used transmissions often have questionable histories that could present a whole new set of problems and issues. New transmissions, on the other hand, are mostly aftermarket transmissions billed as new but are in fact rebuilt transmissions with new parts. Given this, you should err on the side of overhaul. Unless your technician presents you with a cogent and comprehensive reason as to why you should replace your transmission, you should probably opt to overhaul it.

The most commonly asked question of transmission repair is, “how much will it cost?”. Of course this is the most natural question. But there’s no one answer. Every transmission repair is different and we cannot estimate a cost without first running a diagnostic test. However, at Mister Transmission, we are always up front about our costs and will explain to you why any transmission repair will cost what it costs.

Brittney Wilcocks
I was referred to Dan by multiple garages in my hometown to fix my transmission. Dan and his team were very knowledgeable and fixed my van efficiently. He made sure I had a vehicle when I needed one and kept me in the loop the whole time. I would definitely go back!

Jeffrey Maksymyk
I called and they were able to get my vehicle in quick to look at it. It took some time to start the work, but not abnormal. Took about a week to get it back. Able to do a rebuild on my transmission and ended up being cheaper (Toyota wanted almost $11, 000 to fix. Mister transmission ended up being $7300). Sanjay is friendly and took time to explain things. Found the follow-up communication was frustrating at times in that I would have to call to get updates, but probably because they are busy.

My first mistake was to bring my Truck to the dealer for a Transmission oil change, they really screwed up, should have taken to the Experts the first time , Mister Transmission listen to the issue and gave me my options, and lucky me they got it right away. Super professional, they won a new Customer and I will advise them to all my friends and family. Thanks to Ray and Gus.

I honestly cannot recommend Carlo at Mr. Transmission Orangeville enough — 1000% recommend! We came to Carlo after an absolutely terrible experience with another repair shop, where we had already spent thousands of dollars and our truck had been sitting for almost two months. We were frustrated, stressed, and honestly didn’t know where to turn next. From the moment we spoke with Carlo, he listened to everything we had been through and immediately stepped in to help. What had taken the previous shop nearly two months without a proper resolution, Carlo had our truck repaired and back to us in just 3 days. What really stood out, though, was how much he genuinely cared. Carlo went above and beyond for us when he absolutely didn’t have to. His communication was excellent, he kept us informed every step of the way, followed through on everything he promised, and treated us with honesty and respect. After feeling like we had been taken advantage of elsewhere, having someone actually listen to us, help us, and get the job done properly meant more than I can say. Carlo, thank you so much for everything you did for us. We are incredibly grateful. You truly went above and beyond. If you are looking for someone you can trust with your vehicle, I would recommend Carlo and Mr. Transmission Orangeville without hesitation. 5 stars doesn’t feel like enough!

Jacob
Excellent service from beginning to end! I recently had my wife's car serviced and repaired at the Mister Transmission on Barton Street East, and I am very pleased with the experience. Dan was highly professional, and he and his team went above and beyond to ensure we were completely happy and satisfied. They even topped up our windshield washer fluid and washed our car! I highly recommend this Mister Transmission location for any vehicle services and repairs

Janine Auchterlonie
Amazing!! We were in a pinch as we were from outl of town and they did everything they could to help us. It was a Friday afternoon and they called around until they found the parts needed and even stayed late to do the repairs. Both the mechanic and manager were very willing to accommodate and very polite and courteous. Otherwise we would have been stranded for the weekend. THANK YOU SO MUCH!!
