How do Transmission Rebuilds Work?

How do Transmission Rebuilds Work?

Have you ever pondered the existence of transmission repair shops? Why are there entire shops devoted just to the transmission? Most auto shops focus on more than one component of the automobile. They can rotate tires and replace brakes. They can replace mufflers and gap spark plugs. They can install new headlights and new window washer blades. So, what makes the transmission so special?

The long and the short of it is that the transmission is not actually merely one component of your vehicle. The transmission is made up of many smaller components. And all of these parts need to work in conjunction in just the right way for your transmission to operate properly. Some transmission repairs simply require one of these constituent parts to be replaced. However, sometimes finding the problem part is difficult. And sometimes a transmission is so damaged that every part needs to be looked at. This involves a transmission rebuild.

Transmission rebuilds

A transmission rebuild is also known as a “complete overhaul”. Transmission rebuilds are required when the damage done to a transmission is not isolated to one part of the transmission. This can be caused by driving extensively with an insufficient amount of transmission fluid, damaged or old transmission fluid, overuse and overexertion of a transmission, and sometimes transmissions just get old and fail. Whatever the cause, transmission rebuilds are big jobs.

A transmission rebuild requires first that the transmission be removed from the body of the vehicle. Once removed, transmission technicians can then begin disassembling the transmission piece by piece. Every single piece is inspected for damage and just general wear. Those pieces that are deemed to still be in working condition are cleaned in a special solution. Those parts that are too far gone are replaced. In the end, you have a rebuilt transmission that will work properly.

Transmission replacements

An alternative to a transmission rebuilds is a transmission replacement. This involves replacing your existing transmission with another transmission that has already been rebuilt or remanufactured. This may sound like the better option because it should be an easier job, but it’s kind of a risky move. Used transmissions frequently have unknown or questionable histories and could carry problems with them that create a whole new set of challenges. “New transmissions”, on the other hand, are mostly aftermarket transmissions that are labeled as new but are actually rebuilt transmissions with new parts. When you choose a transmission rebuild, the technicians can say with confidence that every part within your transmission works properly.

Transmission rebuild costs

If you can’t tell from the description, transmission rebuilds are pretty labour intensive. These aren’t quick and easy jobs. They take time, knowhow, and a fair few new or refurbished parts in order to do properly. As such, transmission rebuilds are usually some of the most expensive transmission repairs that there are. And let’s be honest, there’s never a good time to need a transmission repair. Many motorists are concerned about the cost of a transmission rebuild. The cost varies for transmission rebuilds depending on a number of factors. At Mister transmission, we offer our customers flexible payment options.

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.

Bobh Yyz
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.
