Before you go to the bank and ready to withdraw stacks of cash to purchase the car of your dream, make sure that you've read this article thoroughly. Every car buyers, especially buyers of used ones want to know if the to-be-their car is in its mint condition before they put the money down. In this article, we'll focus on one of the most important factors in any wheeled vehicle, the transmission system.
1. Check the history of the vehicle
If you want to check the history of a vehicle, there is no better place to visit than websites that allow checking vehicle history such as Carfax. You can find all the possible details about the condition as well as the history of the car. Information such as the number of maintenance it has been through, parts that have been replaced, or accidents it has been involved in.
2. How to inspect different types of transmission
2.1 Automatic vehicle
You need to do a lot of work with this one, generally, there are 3 following problems you need to notice:
When you switch on the key and start the car, you have to wait for 2 to 3 seconds for the car to start rolling. Some people mistook this issue with the issue of the turbocharger-equipped car (because the turbocharger only works when the engine has started for a few seconds). See more about how a turbocharger works in our previous article.
Next, a harsh shift. To test for this, you also need to simply switch gears—you don’t even have to be moving. If the transmission makes a clunking/grinding sound when you switch or the car lurches, then there’s something wrong.

You exchange the minimal effort to shift with the issues to worry about
Next to lagging, you also have to look for this issue. When you accelerate and the system automatically switches gear for you, you feel a little bit rocky. When it happens, the transmission system might have a problem.
This is used to describe the phenomenon when you floor the pedal, and the meter shows maximum RPM but it still goes at its regular speed without accelerating at all. This is called gear slipping.
2.2 Manual vehicle
There are specific parts that you need to focus on when checking a manual such as the clutch. If you're going to buy a discontinued model, the clutch might be in its last days. The symptoms of a car that has a worn-out clutch are slippery acceleration, the excessive smell of burnt fuel.

2.3. With a Continuously Variable Transmission (CVT)
This is a moderately new kind of engine compared to the other two. Some brands have produced cars with CVT such as Audi, Nissan, or Subaru. Having said that, the model is new but the issues are still similar to its predecessors, such as delayed engagement, loud noise when driving, leaky fluid/oil, or clattering.
