Muscle Car Transmission Restoration

Get a step-by-step view into muscle car transmission restorations

Owning and restoring a hot rod or muscle car is as much a labour of love as it is hard work.

As every classic vehicle owner knows, it isn’t all about ensuring your machine looks good, but how it performs too. That work can include muscle car transmission restoration.

Restoring a transmission in a muscle car can be a long-term project. Therefore, when it comes to restorations, it’s critical to find a technician with in-depth knowledge of muscle cars, their transmissions, and how their engines work.

The good news is that Mister Transmission specializes in the repair, service, and maintenance of high-performance vehicles, including classic muscle cars.

Here’s an overview of the steps we take to restore a transmission in most hot rods and muscle cars:

Step No. 1: Access the Transmission

First and foremost, we need to be able to access the transmission. Often, restoration is made easier by removing the transmission from the engine completely. It is extremely delicate work. The transmission is slowly hoisted from the engine compartment, and it must be drained of all fluids and thoroughly degreased before inspection.

Step No. 2: Inspect the Components

s it is by far the most complicated element of the car, there are many parts to the transmission that require inspection. Everything from the mechanics, hydraulics, and electrical systems (if equipped) must be closely examined to determine what needs replacing, what parts require maintenance work, and what parts appear to be in good working condition.

Disassembling the transmission completely, or partially, is often necessary to inspect all its parts. Depending on the age and condition of the vehicle, this can be either a simple job or a more in-depth and complicated inspection.

Step No. 3: Find the Parts

If it’s determined your classic car’s transmission requires new aftermarket parts for it to operate properly, we will go about obtaining those parts.

Acquiring and installing new parts in your transmission occasionally calls for a bit of fancy footwork, particularly if your goal is to install authentic, original components. If so, we’ll contact the vehicle’s manufacturer about obtaining the original parts. Many times, we can source replicas that have the correct decals and information on them that look and work the same as the original pieces.

Step No. 4: Begin the Overhaul

With the necessary parts in hand, we can begin overhauling the transmission. That involves completely taking the transmission apart, rebuilding it, and then putting it back together. When restoring a muscle car, this is the best choice, as it is rare to find a completely original transmission in good working order for older classic cars.

Step No. 5: Replace or Clean Parts

The last step in your classic car transmission restoration calls for the disassembling and cleaning of the valve body. We replace all the bands and soft parts, the lined friction plates, the seals, sealing rings, gaskets, and any other worn out or defective parts. We also need to go over the electric components (if equipped) and assess the torque converter. If the transmission uses a computer to shift gears, it too will need to be inspected.

If you have a transmission or driveline issue with your muscle car or are looking to upgrade to the next level of performance and reliability, Mister Transmission has the technology and experienced, certified technicians to complete the repair work you need.

Alison Kidd
My transmission died while travelling through Calgary. Dawn and Kris were both very kind and helpful on short notice to make arrangements to look at the issue, even though they were clearly quite busy. Once I realized how extensive the damage was, I didn't feel rushed to make a decision, and they didn't charge me anything once I decided not to go ahead with the work. They made an incredibly stressful situation manageable to deal with. Thank you!

My girlfriend and I had to have the flex plate/ flywheel replaced on our 2017 Dodge Journey SXT.We both said “ oh great , we won’t be able to afford to have it fixed.The finance company that financed the car has a list of approved locations that they send customers to for repairs. We have an extended warranty on the car. Thats another story altogether.The first place we took it to ( won’t name the company because that’s going to be a separate review) quoted us $2,300 to fix it with parts and labour. We figured because it was transmission related, we figured that was acceptable. Then we found out that the extended warranty wouldn’t cover it. On top of that, they never took it for a road test.This is where MR. TRANSMISSION comes into play. They are also an approved repair location.We took it there, explained what was the problem was. First thing they did and said was that they were going to take it for a road test, to confirm what the issue was at no charge whatsoever.They confirmed that it was indeed the flex plate / flywheel .Here is where we decided that MR. TRANSMISSION was going to get all of our future business.They quoted us $1,358 including taxes, parts and labour. They also confirmed that the extended warranty wouldn’t cover not cover the cost of the repairs.Now here is where things got even better for us.They deal with a 3rd party warranty/ insurance company that covers repairs, and they approved the repairs for us. All we had to pay was a $53 deductible. Then make bi-weekly or monthly payments.So there was more than $1,000 dollars difference between the 2 separate quotes and they gave us a 1 year warranty on the repairs, no questions asked.So hats off to MR. TRANSMISSION for the awesome customer service and professionalism.They went the extra mile for us.Also a big thank-you to Jennifer for walking us through the process and keeping our frayed nerves to a minimum.JOB WELL DONE MR.TRANSMISSION

I had a great experience...

I had a great experience with Mister Transmission. Before doing any work on my Nissan Murano, they did a complimentary scan and test drive to check the transmission and make sure everything looked good. That gave me confidence to move forward with the transmission fluid change service.They booked me in quickly, were very professional and communicative throughout the process, and took their time to do the job properly. John worked on the car and Mohammed at the front desk was very helpful and honest. They also gave me a very fair price for the service, which I appreciated.It’s been about two weeks since the transmission fluid service and the car has been driving perfectly with no issues at all. Highly recommend these guys if you’re looking for honest and knowledgeable transmission specialists.

My car was experiencing transmission issues, they diagnosed the problem for free, were honest and transparent about pricing and work needing to be done. I ended up not going through with the repairs, but if I need anything in the future I will absolutely be back!

Frank D
I had a leaked enough tranny oil to cause issues with my FJ. I had the issue repaired but there was debris in the pan. I was literally afraid to drive my truck. I had a second opinion today from what I wanted a Transmission expert. The “ nothing is wrong with your FJ” was such a relief. Honestly I would have had a new Tranny installed if that was the verdict. It’s nice to find integrity in service. It’s also nice I am ready to drive my beast again. I take 10 hour trips with it and breaking down that far away is a giant hassle. If I ever do have issues I wouldn’t hesitate to use this place.
