Make sure you have the PCS1 CMD pressure, PCS 2, PCS 3, PCS 4, and PCS 5 CMD pressure, fill Pressure CMD, Time of latest 1-2 shift, Time of Latest 2-3, 3-4, 4-5 Shift,
Trans shift mode, oncoming Clutch, TCC Line pressure, trans engine torque, trans slip RPM, TCC slip, TCC desired slip, Trans input shaft rpm, Trans output shaft and in trans misc. add the trans turbine rpm PIDS.
Clear your charts and put those into groups [Latest shifts group], [C1-5 PCS group], [TCC Line pressure, CL Fill pressure, trans input and output group], [RPM speed latest shift cur gear group] make one for [TCC slip,TCC desired slip, trans turbine rpm, tcc line pressure, trnas current gear] too.
The Pressure control solenoids or PCS is what makes the shift happen. One is oncoming the other is off-going others are steady. What did you change for the Shift pressure>Base shift pressures TCC On tables and TCC Off? You do not want to update the whole table here add only up to 4thgear. Add 30 psi to the LAST 4 columns, @ all rpm range and in each 1-4th gear TCC on and the OFF tables if you haven't.
Have you updated the General shift> Shift Inertia for the single gear changes ...no skip shifting adjustments but add 2 to whole single gear tables. This is a bit subjective and firmness is personal, but it may help with the slip. Did you 0 out the TCC desired slip AC off 1-5th? You also may have the shift times tooo fast for your hardware. Has the tranny been rebuilt for the desired shift timing? There are mechanical limits and if the tune is faster than the physical mods/stock parts it will be unpredictable. Really watch the PCS data in scanner when it slips.
Have fun.
