Thanks for the good report Jerry M.
Since I installed my transmission and rebuilt DZ I have had a stiff operating clutch when the car is fully warmed up. When cold it works fine. Could this be an alignment issue? The block, bellhousing and tranny never met each other before I introduced them. I am pulling the drivetrain during bodywork and will check the alignment for sure now, but is stiff, sticky and hard to shift the clutch when warmed up a symptom of mis-alignment?
