I removed my RMVB and reinstalled an automatic valve body. The auto valve body has been sitting for a few years.
At first the car wouldn't shift into third, but a new modulator fixed that problem.
Now, the car will NEVER downshift on its own. If it is in third, when I come to a stop, it stays in third. I can manually shift it down to first or second, but it should go there on its own.
I'm thinking that the governor isn't working properly. It didn't serve a purpose with the RMVB.
Am I looking in the right direction and can I access it without pulling the tranny?
