TCC RPM Slip = 255 RPMs @25% throttle. Gear 3. If I TOok it to the freeway and started scanning sec.s Before OD would I Get Data For TCC Lockup Rpm For Gear 4? Where Else Can I Get RPO codes?

You didn't do what we asked.

We need slip RPM's in TCC LOCKUP. In OD, above 48mph AFTER TCC lockup.

48 mph TCC lock up RPM' ok, Ill TRY to remember that, ok. Will You Look At both The Factory And The Sinister Perfomance chips Data? :D
