What Transmission Do I Have?

Asking yourself, What are the types of transmission? How to Find What transmission I have? or How to determine my transmission code? Check it out NOW!!

Unless you are a mechanic, or just like to know the ins-and-outs of your vehicle (car, truck, light truck, etc.), there’s a chance that you don’t know exactly what transmission you have in your vehicle. You would be doing yourself a favor to learn a little more about your transmission when you have to get some repair work done or something just doesn’t seem right with your vehicle. Let’s go over the main ways to find out what transmission you have.

How Can I Find What Transmission I Have?

Since there are more than 200 types of transmissions made in vehicles today, it can be very difficult for the average person to determine which type they have. Luckily, there are pretty simple ways to help you determine yours.

Even people with experiences choose to use the simplest methods of identifying the transmission. You can essentially find out your transmission type in a matter of minutes. Stop spending more time than necessary, identify your transmission type with the quick methods below:

Look at The Placard on Driver’s Side Door

You can easily find the transmission type of your vehicle on the white tag just inside the driver’s door. This label also has such information as tire sizes and pressures, gross axle weights, and total vehicle weight beside the vehicle’s manufactured date. This comes in handy when trying to determine what year it was classified as. It also has the vehicle identification number, more commonly known as the VIN.

Use The Owner’s Manual

Another place to find the transmission of your vehicle is the oft-overlooked (and usually still in its original wrapper) owner’s manual. You can most often find any other information you need, including the transmissions that came with your vehicle and the fluid each one requires. It will also have the maintenance schedules, so you can see how often you should be changing the fluid and filter (when possible). If you can’t find the owner’s manual in the glove box, you can find them online, either at the manufacturer’s website or from a website that stores them. If you are still having issues locating your transmission model/type and service info, there are a few more ways we can discuss it.

Find Under the Hood or Transmission Oil Pan

Yet still another way is to either looking under the hood or the oil pan.

Crawl under the vehicle and start looking for part numbers stamped on the side of the transmission or bottom pan. Your local part store or your vehicle’s dealer will be able to cross-reference the numbers to determine the kind of transmission the part belongs to. Or:

Look under the hood and see if any of the tags are attached to the top of the radiator cover, the shock towers, and in some cases, the back of the engine compartment, on what is called the bulkhead or firewall. Take a good flashlight, too, because some of the figures may be difficult to read.

Decode the VIN Number 

The VIN number can be found on either the driver’s side door or on the dashboard. It will be on a white sticker with black lettering that also includes other information about your vehicle. It will be a 17-digit code that comprises a combination of letters and numbers. Each of the numbers means something specific to your vehicle.

To know exactly the transmission type of the vehicle, you can look upon some websites that can help find transmission identification by VIN such as checkmycar.com and autocheck.com.

Also, you can take that VIN number to an auto dealership or repair shop, they should be able to put the VIN number into their computer and tell you exactly what transmission type you have.

What Are The Popular Transmission Types?

Today’s transmissions are varied. In the past, all automatic transmissions had 3 speeds, meaning that they would start off in first gear and shift up into second, then into third or direct drive. In third or Drive, the engine was turning at the same speed as the driveshaft. Those transmissions would not provide the best fuel efficiency, nor would they provide the shift quality we have come to know and expect. Today, 6 speed, 8 speed, even 10 speed automatic transmissions are the norm.

Automatic transmissions in past years were relatively easy to service, and required service usually once a year/every other year. The fluids that were used were very simple to keep up with. Dexron for GM and Chrysler, Type F fluids for Fords. Type A fluid was available, but typically relegated to tractor use and very early automatic transmissions. But now?

Since the early 1970s vehicle manufacturers have been looking for a way to increase fuel efficiency. Engines were modified/number of cylinders reduced while removing weight from the vehicles. The “lead sleds” were fast becoming a thing of the past. As this trend continued into the 1980s, the next logical way to reduce fuel consumption was to reduce the amount of power it took to operate all the accessories. This also included the transmissions. If operating pressures were reduced inside the transmission, the engine didn’t have to work as hard to turn the pump inside the transmission. Unfortunately, lower pressures = higher chance of clutch failures. More changes, along with the advent of computer-controlled engines AND transmissions was the only thing that would work.

In fact, most people think that there are only two types of transmission: manual and automatic. While these are the two main types, there is more to each type than just that distinction.

1. Automatic Transmission

A vehicle with an automatic transmission is one of the most complexes when it comes to how it actually works. But from a usability standpoint, it is the simplest, which is why it is the most common type of transmission on the road today.

The learning curve for an automatic transmission is one of the lowest since it’s so easy to learn.

If all you have to do is to press the brake pedal and move your gear shifter into reverse or drive, you have the luxury of an automatic transmission.

It will automatically shift gears for you as you drive, which makes for a much simpler driving experience.

Of course, there is a mechanical complexity to it behind the scenes. But you don’t have to worry about that unless something goes wrong.

When you open the hood of your vehicle, you may see a code stamped on the transmission, or even a tag hanging on it. This will help you identify whether you truly do have an automatic transmission or not.

The pan shape of the transmission is probably the quickest and easiest way to tell which type it is. Most of the automatic transmissions are either square or shaped oddly.

If you still don’t know whether you have an automatic transmission, you can measure it and find a chart with a quick online search to match the dimensions to yours and identify it.

2. Manual Transmission

The manual transmission is one of the oldest and most trustworthy types of transmissions that are still made today.

You may have heard it referred to as a standard or a stick shift as well.

As the driver, you have to manually operate the clutch with your foot and shift into different gears accordingly.

The learning curve for a manual transmission vehicle is much greater than the other counterparts. But there are some advantages to having one.

Since the transmission is much less complex, it means that repairs will not be as costly or as difficult to fix. Drivers still enjoy a manual transmission because they have more control over how the vehicle runs. Besides, you will generally get better fuel economy than with automatic transmissions.

Identifying manual transmissions can be difficult. The 3-speed, 4-speed, and 5-and-6-speed transmissions all have different characteristics. You can find them in diagrams online if you are unsure about what they look like.

Things to consider when looking at the manual transmission include the position of the selector’s arms, and whether the mounting studs protrude from the side case or if the selector’s arms are secured with a bolt.

Knowing this information, combined with a diagram or chart of common characteristics of manual transmissions, you should be able to positively identify the type of manual transmission you have.

3. Dual-Clutch and Semi-Automatic Transmission

These types of transmissions aren’t very popular for a variety of reasons.

It is essentially a hybrid between a manual and automatic transmission. A semi-automatic transmission has a similar design as an automatic transmission, while dual-clutch transmissions have separate clutches for even and odd gears.

This may seem complicated, but once you get the hang of it, you will see how fast you can shift gears.

Since they have the ability to shift gears rapidly, you can find these types of transmissions in sports cars that are built for speed.

As a result, they are very expensive and, due to the complex nature, are very costly when it comes to repairs.

4. Continuously Variable Transmission

From a driving standpoint, you won’t notice much the difference between a continuously variable transmission (CVT) and an automatic transmission.

From a mechanical standpoint, the CVT uses a belt and pulley system, operated by the vehicle’s computer, instead of gears to create the perfect ratio for the driving conditions.

This is beneficial because it gives the vehicle a much better fuel economy than any other transmission available.

They won’t break down as much or be as costly as an automatic transmission, but they also aren’t as efficient as a manual transmission.

  4. Question need answer??? I have a 2000 Ford Excursion 7.3 L diesel VIN#1FMSU43F5YED18212 . I believe it is a 4R100 trans. But my ? is when I am going down a hill/grade the vehicle continues to pick up speed not holding me back on the hill. I am pulling 34′ travel trailer with it and sometimes dump trailer/enclosed trailer. The transmission is a automatic, I thought in the past that the transmission held me back on the hill when I would lightly touch the brakes. Shouldn’t it down shift thinking like a compression brake?? I had a transmission shop replace the transmission on 7/27/2016 which at the time said they could not get one for my vehicle as the warehouse was out of them. ??? Then all of a sudden one popped up, hidden in the back of the warehouse??? I have thought since they replaced it that it has not shifted on the hill correctly.
    Can you give me your thoughts, idea, etc. I still have under 3 year warranty until 7/27/2019
