I'd say 35mph. The auto will most likely be in 9th. As you approach the drop force it down into 8th and put it in the lightest Jake position. Then like a video game cycle in more jakes as you need them. If the truck exceeds 40mph apply service brake to bring it back to 35. I've done that hill a hundred times and rarely touch the brake.

Fresh oil change fixes this. Otherwise most likely cause is electronic, the ECM runs the Jakes, it needs input from you (Jake switch) and sends signal to Jake controller which directs oil pressure to the Jake rockers.
