Anyone able to explain what’s going on here / how I fix this.. cannot launch for a stop or go WOT 1-2 or 2-3 without this happening. https://youtube.com/shorts/1sJSbRqhbKQ?si=AYDtPVinYTMXStdI - Gearhead tune but did it stock too - fresh trans fluid and filter (did it before also) - no codes - shifts fine through the rest of the gears and 1-2, 2-3 when driving normal. - I can never get trans temp past around 160 after driving for a long period of time even. - clunky going into park?

looqw,
Is there anything loose under the vehicle like the trans mount, differential bushing, diff bushing bolt, etc.?
As recommended, ask Gearhead if a datalog would help him diagnose the problem. The datalog should focus on the transmission - shifts, temperature, pressure, slip along with operating info like load, throttle position, commanded torque, spark, etc. A review of the datalog will show if there is excessive slip or low pressure. Of course, if you feel it is best to get to your local shop quick then they can review the datalog, too, which should help them get to the root cause.
The Service Manual has a troubleshooting section for the transmission but it is a little beyond what most of us weekend wrenchers can tackle. It's good reading anyway.
