This transmission was a workhorse for Chrysler vehicles for many years and was known for its reliability and durability.
It's important to note that while the TF727 was the standard transmission, some vehicles may have had optional transmissions like the Chrysler 904, also known as the "Torqueflite 904", a three-speed automatic.
To be absolutely sure about the specific transmission in your vehicle, you should check the following:
* Vehicle Identification Number (VIN): You can decode your VIN to find out the exact model and options of your Grand Wagoneer.
* The transmission tag: The tag is typically located on the transmission case itself and will have information about the transmission model.
* Service records: If the vehicle has previous service records, they may indicate the transmission type.
