The 4 cylinder T5 trans has a 3.97:1 first gear so, it will wind up very quickly. If you blink you will have hit the redline in first gear before you know it. It also has a lower torque limit spec, 235 Ft/Lb, so it may break easier than a V8 T5. The pilot shaft is smaller, so you will need a different pilot bearing.
The pilot bearing you need is for a Ford Ranger diesel from AutoZone part #14672 - hope this helps!!!
