* 4L60-E: This was a very common 4-speed automatic transmission.
* 700R4: A 4-speed automatic, though less common than the 4L60-E in the G20 by 1993.
* Manual Transmissions: While less frequent, some G20s were available with manual transmissions, but the specific type would depend on the engine and configuration. This information would be needed to give a specific answer.
To know for sure which transmission is in *your* 1993 Chevy G20 van, you need to check:
* The vehicle's identification number (VIN): A VIN decoder can often provide transmission information.
* The sticker on the driver's side doorjamb: This often lists the transmission type.
* The transmission itself: The transmission case usually has identification markings.
Without more information about your specific van, it's impossible to say definitively which transmission it has.
