Transmission slip?

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