How do I identify my Ford manual transmission?

The quickest way to identify your Ford manual transmission is to read the ID code stamped or tagged on the transmission case and cross-check it with Ford's official part records or a dealer database. If the marking is unreadable, use your vehicle’s VIN and build sheet to determine the exact gearbox installed.

In this guide, you'll learn where to find the transmission ID code, how to interpret it, how to verify the transmission using the VIN/build data, and what to do if labels are missing or damaged. The methods apply to most Ford cars and trucks with manual gearboxes, from older models to modern ones.

Find the transmission ID code

Many Ford manual transmissions carry a model or serial code stamped on the case or shown on a small tag. Reading this code is often the fastest route to a precise identification.

Look for a stamped identification code on the transmission case, typically on the bellhousing face or the side of the housing. The code is usually a short string of letters and numbers that identifies the gearbox family and model.

Some models use a small metal tag attached to the case with the gearbox model name, number, and sometimes production date. Photograph or write down all markings.

If you replaced the transmission before, there may be a non-OE unit with a different code—note any aftermarket labels as well as the OEM markings.

If the markings are faint or missing, take clear photos of the entire transmission and seek guidance from a Ford dealer, mechanic, or a dedicated Ford parts database.

With the ID code in hand, cross-check against Ford’s official service information or a reputable parts catalog to confirm the exact transmission model and compatible parts.

Use your VIN/build sheet to confirm the transmission

Your vehicle’s VIN is linked to its original drivetrain configuration, including the transmission. When possible, use it to confirm the gearbox originally installed by Ford.

Locate the VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s door jamb, and note it down.

Enter the VIN into Ford’s official VIN decoder or ask a Ford dealer to pull the vehicle’s original equipment list. Look for the drivetrain/transmission entry to identify the gearbox.

If you still have the original window sticker or a build sheet (often found in the glove box or with the original sale documents), check the Drivetrain or Transmission line for the exact model name or code.

Be aware that aftermarket changes or replacements after delivery may not be reflected by the VIN alone; when in doubt, compare the ID code from the case with the VIN-derived data and consult a professional.

VIN-based confirmation is typically the most reliable way to verify the factory-installed transmission, especially if case markings were removed or replaced.

Visual clues to narrow down the identification

If you cannot read the ID code or lack a VIN lookup, you can narrow the possibilities by inspecting the gearbox's physical traits and the number of gears.

Gear count and shift pattern

Count the forward gears visible on the shift pattern (for example, 4-speed, 5-speed, 6-speed). The shift knob or boot often shows the pattern, including the reverse position. Modern 6-speed units typically have a distinct 6-speed pattern versus older 4- or 5-speed systems.

Bellhousing, case layout and mounting

Different transmission families have characteristic bellhousing shapes, mounting flange patterns, and input shaft alignments. Compare the general layout with photos from Ford service manuals or reputable repair guides to narrow down the option set.

Cast markings and external tags

Some units bear a cast-in model number or a side tag near the bellhousing. Even small numbers or letters can identify a transmission family. Photograph these marks and search Ford parts catalogs for a match.

What to do if you still can’t identify it

If markings are unreadable, the VIN/build data doesn’t match, or the transmission has been replaced with an aftermarket unit, seek professional help.

Contact a Ford dealer’s service department with your VIN and vehicle details; they can pull the exact original transmission using the VIN and build data.

Bring the vehicle to a trusted shop with experience in Ford manuals; they can often identify the gearbox by internal features or by comparing the input shaft, output shaft, and gear ratios during inspection (this may require removal of the transmission).

Consider obtaining a formal build sheet or factory documentation from Ford Customer Service or an automotive data service if you need definitive provenance for resale or parts compatibility.

In some cases, a historical record or exact replacement part may be necessary to ensure you order compatible parts or schedule the right maintenance schedule.

Summary

To identify a Ford manual transmission, start with the ID code stamped or tagged on the case and verify it against Ford’s catalogs or a dealer. If markings are unreadable, use the VIN to pull the original drivetrain configuration, and consult build sheets or the window sticker. Visual clues—such as gear count and mounting layout—can help, but the ID code or VIN-based confirmation remains the most reliable method. When in doubt, contact a Ford dealer or a qualified mechanic for definitive identification.

How to identify a Ford manual transmission?

You can find your transmission type on your window sticker, a Build Sheet, or a Vehicle Identification (VIN) Decode Letter. To find the transmission types on any of our current models: Visit the Ford website. Click on Vehicles to select a vehicle.

Can my VIN number tell me what transmission I have?

Yes, a VIN can often tell you what transmission you have, but it's not guaranteed as a specific digit solely for transmission is not always required in the VIN standard. You can use a VIN decoder tool from a site like Edmunds or the NHTSA to get detailed vehicle information. The 4th through 8th digits of the VIN often contain information about the transmission, model, and engine, and the information provided can range from basic (manual/automatic) to detailed depending on the manufacturer and model year.
How to use the VIN to find your transmission

Use an online VIN decoder: Enter your 17-character VIN into a decoder tool. Websites like AutoZone, Edmunds, or the official NHTSA VIN decoder can provide a breakdown of your vehicle's specifications, including the transmission.
Check the 4th through 8th digits: For many vehicles, the 4th through 8th digits provide information about the model, engine, and transmission. For example, one character in this range might indicate a 5-speed manual or an automatic transmission. Be aware that the coding can vary between manufacturers and model years, so a decoder is the most reliable method.
Contact the manufacturer or dealership: If online tools don't provide the exact detail you need, a dealership's parts department can look up the specific transmission model using your VIN.
Look for physical labels: Some transmissions have a metal plate or sticker with an identification code that you can use to look up the model.

How to identify a Ford T18 transmission?

The Ford versions can also be identified by its numbers cast into the driver's side of the case, commonly "T18-1E" for earlier units and "13-01" for later units. From 1966 until 1978, many T18s used a T98 shifter assembly. 1979 and newer T18s used a three fork shift cover assembly that shifts reverse gear directly.

How do I tell what manual transmission I have?

You can identify a manual transmission by checking your owner's manual, looking for a white placard on the driver's side door jamb, or using the vehicle's VIN. Other methods include visually inspecting the transmission case for labels or casting numbers, which can provide model-specific information.

Vehicle-specific information

Owner's manual: The owner's manual should specify the type of transmission your vehicle is equipped with.
Door jamb sticker: Open the driver's side door and look for a white sticker with a barcode and vehicle information, which may include a code for the transmission.
VIN decoder: Use the Vehicle Identification Number (VIN) on a site like the NHTSA's to get a detailed report on your vehicle, including the transmission.
License plate lookup: Some online services can provide vehicle details, including the transmission, based on the license plate number.
