It doesn't have a dipstick. The red cap on the driver's side of the tranny is where ATF (Dextron-III) is put in. The level is checked by removing an inspection plug located on the passenger side of the tranny on the right transaxle housing. If you jack it up and look underneath it will be adjacent to the engine oil drain plug. The level must be checked with the vehicle level.
