Well, bit the bullet and dropped a new "corvette" governor in. Wot shifts are now:
So, I still have some variation in shift points, but I am back under the rev limiter.
Tomorrow I will "sneak" up on an rpm that will keep me around 5500rpm
BTW, I did get advice from a local transmission shop owner that said to forget the governor kit, and simply grind mass off of the existing weights. He said tha the kits work for th350s, but are more trouble on the 700r4.
