126K on 96 GL Duratec ATX. I've done the drain & refill (2x) routine every 6 months for the last two years. This last time (yesterday) I included Lubeguard. So far I've used 3 different types of Valvoline ATF fluids:

1) Durablend synthetic blend, Dex III, Mercon, Mercon V
2) Mercon V
3) Dexron III, Mercon w/Lubeguard red bottle

If I knew for certain the TransGo Shift kit would put me over 200K I'd do it in a heartbeat, but ... I'm keeping my fingers crossed.
