A tranny was give to me and i don't know exactly what kind it is and what it came out of. The ID# is 13-52-065-908 on the main housing and 13-52-066-919 on the tailshaft housing.
Many of the T5's used the same castings and external parts. The only way to accurately identify a T5 is by the aluminum tag screwed down under one of the tailshaft housing bolts.
Look at the chart. The 4 cylinder T5 does have a smaller input shaft. It may require either a V8 input shaft to do a side by side visual comparison or a mike or dial caliper to measure it.
