It looks like it bounced off the rev limiter when traction was lost at the high end of 1st gear...

(it looks like 1st gear to me... but the GEAR pid wasn't logged).

Either traction was severely lost (50mph -> 80mph in 0.2s) or the VSS sensor is faulty and/or picking up noise... I don't think you lost traction since the RPM jumps up only 100-300 rpm... I think there's a VSS problem.

Then it looks like it shifted 1->3... when VSS shot up to 80mph, the WOT 2->3 MPH condition was met so it shifted into 3rd.

It looks like it never went into 4th during WOT (it went into 4th after the throttle was released.
