Update. Following last week complete car computer system wipe, the transmission has behaved like a champ this morning. No hesitations, no jerkyness and I was even graced with a little kick down passing a car on the high way. Transmission behaved very well and was smooth in bumper to bumper trafic. Over all, the current behavior is on par with what I had post FSA 12B37 this summer.
