if you want to find out, put it in low and count how many times the output shaft shaft turns for one revolution of the input shaft. If it turns 4.7 times, you have 4.7s. If it turns 2.28 times, you don't.
ALso, people will want to know what year it came out of since not all 4cyl t-cases are the same. Some are top shift and some are forward shift.
