As far as I know there isn't a speed sensor on this trans, or if there is I don't know what would be reading the speed. I've got a N/S plug and the other three wire plug coming off of the OD/TC solenoids, and that's it. If the vehicle speed sensor monitors that, then I'm going to go ahead and replace it. I'd driven without it working for years so just have been ignoring it. I monitor my speed by rpms and sound. It's second nature now.

I would love to know more about how temp affects this trans, as it pretty much dictates whether I have OD and TC lockup, sir. I can't thank you enough for all of your help. This project scared me to death, at first, but now I'd tear another 46rh apart in a heartbeat and rebuild one.
