Im seeing over 1500rpm of Trans Slip rpm when the trans commands the 3-4 shift attached log and editor file. Is this normal seems excessive and costing me some time and power.
Just a bolt on car with E85.
Can this be fixed in the TCC Pressure settings?
Thanks

Additionally, locking a (factory) single disk converter is not a good idea. It will ruin it and send bits into the transmission, then you gotta rebuild the trans and converter. I would suggest NOT locking at WOT for the safety of the car. It is slipping because it can't hold the power.

Those are set to lock WOT on the stock calibrations all except 1st gear. As are many 6 speed stock calibrations.
The 6l90e has a nice dual carbon clutch too.. very good converter

have you tried adding 40-60psi to the tcc and zero all tcc, set tcc gain to 1???
