Just had my trans rebuilt after breaking the direct drum (http://www.turbobuick.com/forums/transmission-talk/229782-lost-od-highway.html). Seems to shift as it should at part throttle, it’s responsive and firm. I have not yet checked the full throttle shifts. It shifted great before I broke the drum. It’s a CZ trans with CK’s shift kit (which is great!) and has the basic hard part upgrades. I’ve never fried clutches in this trans (just broken hard parts!!)
Should I be concerned with the pressures below? Compared to the pressures in CK’s manual, my pressures at MinTV are higher and my pressures at MaxTV are lower. How can I fix this? Does it need to be fixed? Can this hurt anything or am I just not getting optimum clamping force on the clutches?
