GEN 2 Abrupt jerk after lifting off throttle

Same here. Feels like abrupt lock up of the TC.

no solution found at my end yet. looked at wheel speed sensors, no codes, all fluids are topped off, no leaks, multiple ecu/tcu resets and relearn cycles, checked transmission fluid levels, drained and filled trans fluid, replaced filter, monitored ABS in forscan, checked 4A/4H functionality...can't remember what else I looked into, and it still does it from time to time.

Still the same trigger for the symptom, normal driving then going WOT in a short burst. Abrupt drop off and you get flung forward like you're gonna eat the dashboard when lifting off gas pedal.

I'm starting to get convinced this is a programming issue. goosetuned e50 and tcm.
