Interchange Fitment FAQs
A: All Transmission options shown on this page are matched to your selected configuration:
1966 Mercury Comet.
Used OEM parts are dismantled from donor vehicles as complete assemblies, and a specific interchange fitment is assigned during this process.
Every detail shown in the fitment notes must match your vehicle exactly.
A: An interchange fitment option defines the exact donor vehicle configuration your part came from. For 1966 Mercury Comet, this may include engine size, VIN code,
transmission model, drivetrain, axle ratio, and other critical identifiers. This data comes from VIN decoding, OEM information, and
physical inspection of the donor vehicle.
A: Used OEM parts are not universal. If any fitment detail for your 1966 Mercury Comet differs from what is shown in the fitment notes,
the Transmission may not install, communicate with your vehicle, or function correctly. Always verify all fitment details before ordering.
A: Fitment information is captured when the donor vehicle is dismantled.
The yard decodes the VIN for 1966 Mercury Comet, checks OEM data and interchange databases,
and verifies details during physical inspection. The resulting fitment is then assigned to the Transmission assembly.
A: Many 1966 Mercury Comet vehicles were built with multiple configurations in the same year and trim. Trim name alone (XLT, Limited, Sport, etc.) is not enough.
You must match the exact configuration shown in the fitment notes—such as engine size, transmission type, drivetrain, and axle ratio—before selecting a Transmission.
A: You can find the VIN for your 1966 Mercury Comet on
the driver-side dashboard (visible through the windshield), inside the driver-side door jamb, and on your registration or insurance documents.
The VIN helps confirm the correct configuration and fitment.
A: For transmission fitment, match transmission type (automatic or manual), number of speeds, drivetrain (2WD, 4WD, or AWD), and transmission model as shown in the fitment notes for
your 1966 Mercury Comet.
All of these must match before you select a transmission.
A: 2WD, 4WD, and AWD transmissions are not interchangeable even if they look similar. The interchange fitment is assigned to the transmission based on the donor vehicle’s drivetrain,
so your 1966 Mercury Comet must have the same drivetrain for the transmission to fit correctly.
