Here's why:
* Year Range: The 1992 Rodeo was part of the first generation (1990-1997). During this time, Isuzu offered a 4-speed automatic as the standard transmission for the 3.1L engine.
* Manual Option: While a 5-speed manual transmission was available in some 1992 Rodeo models, it was generally offered with the 2.6L engine, not the 3.1L.
However, to be absolutely sure:
* Check your VIN: You can use your vehicle identification number (VIN) to look up the exact specifications of your 1992 Rodeo on websites like AutoZone, PartsGeek, or Carfax. This will tell you the exact transmission type.
* Look under the hood: If you're comfortable with a little bit of car work, you can look under the hood for a sticker on the transmission itself. The sticker should indicate the transmission type and model number.
Remember, without knowing your exact VIN or having a look at the transmission itself, it's only possible to give a general answer.
