What Is a Transmission Rebuild?

By Mister Transmission

Learn what’s involved with rebuilding a transmission and if it’s a worthwhile proposition

Take care of your wheels through regularly scheduled preventative maintenance of your car’s transmission, and you may never need to know about transmission rebuilds. However, despite the most devout car owner’s efforts to stay atop of any potential engine troubles, the ravages of time will eventually catch up with your treasured vehicle.

If you’re facing the prospect of a transmission repair, it is helpful to understand what your options are. By knowing a little about rebuilt transmissions, you’ll be better equipped to determine whether you should choose to have your transmission rebuilt, of if you should purchase a new one. Regardless, understanding more about either option may save you money and extend the life of your car.

New Parts May Not Stave off the Inevitable

As it is with any failing mechanical or electrical device, if a potential problem with your vehicle’s transmission is detected early, any repairs or adjustments may be made without requiring a full transmission rebuild.

If there are transmission parts that require replacing, and they are easily accessible, or if the problem is an electrical one, it may be possible to repair the transmission without removing it from the vehicle – that alone will save you time and money. That said, it may be wise to look at the big picture right from the start, and have the technician thoroughly inspect the transmission.

If a few parts of your transmission are damaged, it’s quite possible other parts will require replacing too. But know once the parts replacement process starts, it can become a losing battle. A transmission rebuild may, in fact, be the wisest and most economical choice you make.

What Is the Transmission Rebuild Process?

An important element of transmission diagnosis is determining the cause of the problem, enabling you to make an informed decision whether or not you should proceed with a transmission rebuild. The transmission rebuild process typically includes:

  • Removing the transmission from your vehicle and dismantling it
  • Chemically cleaning the transmission by running it through a parts washer
  • Any wonky transmission parts, plus all seals and gaskets, are replaced with new ones
  • Any required electrical repairs are performed
  • There may have been advances made in your vehicle’s transmission parts and technology since you purchased your car. If so, these updated parts may be included to improve the performance of your transmission and extend its longevity
  • Last but not least, the rebuilt transmission is re-installed in your vehicle

The Cost of a Rebuilt Transmission

As with any automotive repair, the cost of a transmission rebuild varies widely, and it’s determined by a multitude of factors including the type of vehicle you drive, and how extensive the damage is to your transmission. A word to the wise: nobody can tell you exactly what your vehicle’s transmission repair will cost over the phone.

While cost is always an important consideration when faced with a transmission repair, it is also important to consider the value of the repair work performed as well. If the transmission technician or shop you’re dealing with doesn’t offer a 12-month warranty on a transmission rebuild with the option of upgrading it to a five-year warranty on all parts and labour, you’re settling for less, and you may be playing Russian roulette with your vehicle.

Liz Gosselin
My 2016 Dodge Journey would not pick up speed without revving at a really high rpm. Transmission was slipping and revved hard in reverse. Took it in to Mister Transmission on Portage Ave knowing I most likely needed a new transmission. Got them to check and yes I needed one. They gave me the money back for the diagnostic and I paid for the new transmission. They also provided me with a courtesy car for 5 days. They did the work so quick and made sure my car was fixed properly. My car runs like a brand new vehicle. It picks up speed, rpm is good, and doesnt shake in reverse anymore. Special thanks to Phil and the team for repairing my car and getting it back to working order. They also have a good warrenty on the new transmission. Completely worth the money. Thanks guys.

I cannot say enough good...
Shane Whitehead
I cannot say enough good things about dealing with Mister Transmission. Their staff are extremely knowledgeable and went above and beyond while working on my transmission. They brought out the filter and pan and explained what they suspect happened before even pulling the transmission apart. They were kind enough to take me into the shop and allow me a visual of what I was looking at and was able to walk away more knowledgeable than going in.They gave me a ride home in their personal vehicle as they did not have a shuttle and didn't even mention taking a taxi as if it wasn't an option.They stuck around late on a Thursday of a long weekend (Friday being the holiday) to ensure the vehicle was returned to me before the long weekend and leaving me without a vehicle for an additional 4 days.I will be returning for fluid changes and any other concerns with other vehicles in the future.

Christian Karimlou
I had a serious issue with my transmission on my 2017 Civic and brought it here. The team at Mister Transmission did an amazing job diagnosing and fixing everything properly. They explained the issue clearly, kept me updated, and the customer service was top tier from start to finish.They replaced everything needed and got my car running like new again. Was charged for a very fair price for the amount of work that was done.Honest, professional, and reliable I highly recommend them if you’re dealing with any transmission problems.
