Re: Weird RPM flux when driving..
Yep, that just seems to be the verter locking (rpm drop plus you should feel the verter clutch when it locks, Its a jerky feel) and unlocking. I have mine locking in 6th gear only part throttle, normal and sport, and 5th and 6th when in manual. It helps with the locking clutch longevity plus the locking feel can be a biatch if you are not use to it. Locking 6th only is all we need for daily driving unless you drive around long hills, in which case you can use manual and ask to lock 4th,5th and 6th depending on how hot things are getting in the trans.
