If yours is happening in the 3 to 5 gear range it maybe a shift flare. My truck would rev up every so often when it was shifting between 3 and 4th gear and it woud feel soft and mushy when it did it. For me it would only happen or I would only notice it when I was at half throttle or less and once again this would only happen every so often. It would also feel like it would get stuck inbetween gears or couldn't find the right gear sometime if I was braking hard for a stop light and then get back into the throttle before coming to a complete stop. To fix it for me I first tried traction bars thinking that woud fix everything but it didn't. Traction bars are great for everything expected fixing the shift flare. The thing that fixed it for me was a modified DD shift solenoid from PTP for $150. It makes the 3 to 5 gear shifts faster and more solid feeling. I've had mine installed for maybe 500 miles or so and not one shift problem yet. I hope that helps. If you do it I would recommend doing a transmission relearn on it after install. My shifts were a little to firm at first until the relearn was done.
