Wondering what is normal for T-56 shifting effort. While driving around town and shifting between 4-5K the ease of stick movement is light, buttery smooth. However, when shifting at cam shaft red line of 6500 rpm stick effort is noticably increased. Sometimes it feels like I have to literally slam it into gear. Currently there is Mobile 1 synthetic ATF as the lubricant with about 1000 miles run time. The shifter is a Hurst Pro Billet, their top of the line if that means anything. I don't think the clutch is sticking but uncertain how to check that. The clutch is a Centerforce Dual Friction with their billet flywheel. The tranny was rebuilt by a good shop and told it was in great shape so don't think the syncros are shot, if it even has syncros (goes to show how much I know about T-56 trannys). Any ideas what is causing the high shift effort in the upper rpm range?
