I have done a complete drian of all 11 qts and replaced with new fluid (mercon 5) & filter change. Between 45-55 mph the truck is running at about 1400 rpm's (4.2L) but when needing to accelerate or approaching inclines the transmission will make a couple of bumps shifting out of OD. If I'm getting on interstate and accelerating up to 70 mph it passes right thru this cycle to OD without any problems. I have read that shifting bands my be the problem (anyone know how much that might cost) or anything else I can check first.
