99 & up 7.3L Power Stroke Engine & Drivetrain
Everything seems to be going well but I have a question:
Normal shifting pattern under normal light/moderate acceleration: 1, 2, 3, 3 lock (35-40 mph), 4 w/lock (45+mph depending on accel rate).
Note it shifts into 4th immediately and locks - or stays locked. Is there such thing as 4th unlocked...
