Choosing the Right Transmission Fluid

By Mister Transmission

Choosing the right transmission fluid is one of the most important things a driver can do to keep their vehicle safe – and avoid unwanted car repair costs!

How to choose the right transmission fluid

The best place to start is by consulting the owner’s manual. It will note whether the car requires Dextron or Mercon transmission fluid. It’s very important to follow the owner’s manual. For example, some imports won’t accept Mercon, and instead require brand-specific fluid.

Synthetic or conventional transmission fluid?

Car owners also need to choose between synthetic or conventional transmission fluid. Synthetic fluid is more costly, but provides better performance and is more durable at higher temperatures. However, on some older models of cars, it’s actually better to stick with conventional fluid – especially if synthetic has never been introduced. Making the switch can actually do more harm than good, and lead to unwanted transmission repair issues.

Choosing the right brand of transmission fluid

Once the right type (Dextron or Mercon) and quality (synthetic or conventional) of transmission fluid is chosen, the next step is to find the right brand. There are a number of popular and well-regarded manufacturers, including Mobil, Shell, Penzoil, and more.

At Mister Transmission, our mechanics have in-depth knowledge and training, and provide our customers with sound advice on which transmission fluid brand gives them the best performance within their budget, and therefore helps them avoid unwanted car repair issues (including the need to rebuild a transmission) down the road!

Aljonder Leycano
I recently took my Chevrolet Equinox to this transmission specialist because I was concerned about what I perceived as unusual RPM behavior. The staff there, especially a person named Jamie, were incredibly adept at breaking down complex automotive concepts into simpler terms that I could easily grasp. They reassured me that the RPM behavior of my 4-cylinder engine was normal.The service went above and beyond my expectations. They had already conducted a road test, but when I called, Jamie suggested I could also take a test drive accompanied by a technician named Stephane. This offer was very reassuring, allowing me to see firsthand that everything was functioning as it should. The most remarkable part of the experience came at the end. Despite their professional and comprehensive service, they did not charge us for their time and effort. Their expertise, excellent customer service, and generosity greatly impressed me, and I would strongly recommend their services to anyone in need of trustworthy and proficient car care.

Great service and great price. They weren’t able to look at my truck until the following week when I was away. They stored it for over a week and kept it inside during the snow. Appreciate it

These guys (Chris & Dawn, and Crew) are absolutely amazing I couldn't recommend MR Transmission enough!! I have a 2016 f150 with the 6R80 and for a little while I had almost every symptom of a bad torque converter expecting to need a full rebuild, I called in a asked for a worst case scenario qoute and was asked to bring it in, I was expecting a $4-7k rebuild I was 90% sure it was the torque converter, with a quick scan and diagnostic it was found the output speed sensor had gone and Chris without looking at a book or a screen 1300$ was the qoute and 1250$ was the final price these guys know what they are doing but the most appreciated thing you guys did for me was rush the repair knowing I had no way to get home to wait for the repair to finish they allowed me to wait in the shop and offered me coffee I really appreciate you guys. thank you for being a HONEST shop you could've just said oh yeah needs a torque converter and i would've believed you, but you didn't so thank you I will be recommending you to anyone I come across in need of you're amazing services!

Peter Urbanski
Ray and Gus are my transmission guys from now on! Ray filled me in on any possible aspects of what can be wrong with my 1993 Lincoln TownCar He used to fix them (also Crown Vic's) back in the nineties Then, he had changed the fluid as the first step It's been two months since then, and my Lincoln is smoother then ever! My point is, Any shop can change the transmission fluid, but most of them will tell you "You need a new transmission" Honesty and integrity, which we all long for Sorry Rayfor waiting two months to write this, but I had to make sure I don't "jump the gun" to praise you!
