[QUOTE="Duster, post: 448125, member: 20812"] It sounds like fuel starvation or excess under load. When you reduce the demand the power band remains where it ought to to be. When you put the hammer down, you are increasing fuel flow and air intake, or should be. If either or both are slightly off high demand will enhance the effect. The change is correlated with a new transmission, but you don't say whether the transmission is simple replacement or intended as an upgrade, or what type of transmission it is. If the transmission is of a different gearing, that [I]might [/I]be an issue. The only vaguely similar thing I ever experienced was due to a glazed clutch. My truck would begin slowing up steeper hills even that the engine RPM increased. [/QUOTE]
