Did you ever clean the splines? I have a new transmission jack, bolts, and grease. Just haven't yet put it on jack stands and gotten started. You stated exactly how I feel. It is not bad enough to turn it loose with someone else. Ken
9r23 doesn't have the throttle boost option, and yes, the delay happens in 4th, 5th and 6th as you described. Rolling back to 9r23 forces the CalID to be rolled back - the newest CalID what's causing the delay.
