* 3-speed automatic: This was a common transmission in many models.
* 4-speed automatic: Also possible, though less frequent than the 3-speed.
* 5-speed manual: Many models offered a manual transmission option.
To know for sure which transmission is in a particular 1990 Dodge V6, you'll need to check:
* The vehicle identification number (VIN): A VIN decoder can provide detailed specifications including the transmission type.
* The owner's manual: If you have the original manual, it will specify the transmission.
* The vehicle's data plate: Located typically in the engine compartment or on the driver's side doorjamb.
* The transmission itself: Look for markings on the transmission casing which will identify it. However, this requires some mechanical knowledge and may not be easy to access.
Without more information about the specific Dodge model (like Ramcharger, Dakota, Caravan, etc.), it's impossible to say definitively which transmission was used.
