The two th350s in my possession have different governors in them. The governor from my old th350 (built to unknown specs) has much lighter springs than the new one. The new one has noticeably heavier springs. I know what the governor does, and I suspect the one from my old tranny is the one I'll want to use, but is there any way to figure out exactly what the differences are going to do after the fact (i.e. Not having a set of springs to choose from, but just taking what happens to be there). Are the springs color coded? Looks like the ones in my old governor were white if that matters. And I thought heavier springs would raise the shift points, and lighter ones would lower it. Is that right? If so, maybe I want the springs from the new governor? If I do want to keep my old governor (which is what I think I want to do) the drive gear is busted and shaft is scored from the broken case. If I'm right, I can just use the head assembly (weights and springs) from mine and the shaft from the new one and that should get me what I want. Correct?
