New converter installed and on the dyno this thing shudders horribly in 5th and 6th. If I unlock converter via vcm controls it goes away instantly. I have set the tcc slip tables to 0 in 5th and 6th gear. I?ve tried increasing the min tcc pressure etc etc. I even flashed the stock file back into it with no luck. Slip err fluctuates +/- 10% or so at the most when locked. Tcc pressure is falling in line exactly as commanded. Even locking the converter with the vcm controls (max line pressure) changes nothing.
I think it?s a converter issue so just checking here to see if any of you guys may have experienced something similar. Tcc locks at wot and does not slip. Pulls clean to 7k rpm in 4th every time. Gonna check trans fluid level again in the am but we checked it earlier and it was fine however trans temp was slightly higher than it should be for checking level.
Thanks guys for any help offered.
