A couple questions first:
1) Why do you want to get your tranny "refreshed?" Is it grinding, leaking, etc.?
2) How many miles are on your T5?
My guess would be that "refreshing" your tranny would include all or some of the following:
- installing new syncros
- inspecting the gears for excessive wear or chips
- changing the fluid
If your tranny feels fine, I would just forgo the "refreshing." Plus, if you decide to get it rebuilt your looking at least $500. I was actually quoted $700 for a rebuild
