Slave is on the tranny side of the bell housing.
It will shift into 3rd and 4th, but it is difficult. Even into 2nd when first starting up but then gets harder as it warms up. It shifts easier when I let up on the clutch pedal a little and the grinding whirring noise goes away. I think the throwout bushing may be bottoming out in the pressure plate or dragging on the tranny input shaft when the clutch pedal is pushed all the way down causing the whirring noise. With the clutch pedal all the way down, the car will actually start to creep while in gear. Let up a little on the clutch pedal and it stops creeping. Let up a little more and the clutch starts to engage. The throwout moves in an arc described by the motion of the clutch fork.
When I was bolting it all together, it seemed like the forks on the pressure plate did not sit as high as the one I had removed. That may be because the old clutch had worn and the old pressure plate was a very old one that had been turned once. If the clutch wears down a little, the forks on the pressure plate will sit higher and that may give me more room to release the clutch before the throwout bottoms out in the pressure plate or drags against the tranny input shaft.
I just pulled the tranny filler plug and the oil is foaming something fierce. I assume that is because the oil I put in was detergent (even though it said non detergent) or incompatibility with the oil that was used when the tranny and OD were rebuilt. I am going to change the oil (problematic because California has outlawed SAE30ND oil). I don't know if that will solve my problem, but one step at a time.
Does anyone know if compressor SAE30 oil is the same as SAE30 motor oil? Compressor oil is available in California, but motor oil is not. I'm not sure if compressor oil may have some additive that is bad for the brass in the tranny or may cause a problem with the OD clutch. Both kinds of oil are labelled API SA/SB. Of course, I can always ship in some oil, but none of the auto stores or even Tractor Supply will ship because of the regulations. Walmart seems willing.
