* 700R4: A 4-speed automatic overdrive transmission. This was very common in many configurations.
* 4L60E: A 4-speed automatic overdrive electronic controlled transmission. This was also frequently used, often replacing the 700R4 in later production years. It's possible a '92 would have this, but less likely than the 700R4.
* SM465: A 4-speed manual transmission. Less common, particularly in the later years of the second generation Blazer.
To know for certain which transmission is in *your* specific 1992 Chevy Blazer, you need to:
* Check the vehicle's identification number (VIN): A VIN decoder can often reveal transmission information.
* Look under the vehicle: The transmission case will usually have identifying numbers cast into it.
* Check the owner's manual: If you have the original owner's manual, it will specify the transmission type.
Without more information about your specific Blazer, it's impossible to say definitively which transmission it has.
