Trans slipping? *video*
Maybe get a longer video? Or if you want to see if the trans is slipping just put it to the floor from a dead stop, do the tires spin? or does it hit the rev limiter?
Heres a video of a converter in my car. I gave it more throttle at 5 seconds, and at :23 the clutch locks. But it shows how a loose converter will maintain the same rpm through shifts at light throttle.
