Transmission slip?

Hey guys,
I’ve started to lean on my car, and logs are showing some non linear changes in rpm. Could this be normal flash? The second graph is a 2->3 shift where it appears to take a second or 2 for the rpm to settle.

—-Edit— realized the first picture is wheel spin in 2nd

I can feel this slip in my car. Sometimes it will blow the tires off mid second gear, and sometimes it just feels…soggy?

My transmission should be up to the task, but my converter is questionable. Transmission is a fully built cope roller. Converter is a billet 9.5” setup in the tightest configuration the company(Gillece) has available. 3.25 gears, 28” tire

Power SHOULD be north of 800 crank on these pulls, but I can’t say it feels that strong.

You can feel it slipping so you are not Now to determine what is slipping.

Cope? Does it have a cope valve body? Then yes it is slipping! LOL

What is the amount of time on the graph left to right.

Is this a joke? I was under the impression his stuff was quite good so I need corrected if that’s wrong.

I’m not sure if what I feel is slipping. It doesn’t feel like a clutch slipping where RPM’s just flare up. It just feels soft. Also your question of time is the correct one. With zero slip this entire pull would represent 75-150mph in 3.42 seconds. Something is slipping A LOT.

I thought if I was blowing through the converter I wouldn’t experience a rpm drop on the shifts and it is dropping 1000rpm
