A904 Hard 1-2 Shift and Reverse

Hard to say without a tachometer. However, I turned the idle down quite a bit and reverse has settled down to normal now only 1-2 is hard shifting. I didn't realize how high the idle was, purrrrs like a kitten now. Thank you for that Mike
Good to hear. If you look at the illustration above, the slotted rod should just slide over the pin setting in the idle position. If it is under spring pressure you can unscrew it until it is in the right position. The shift mph can be fine tuned from there. That is a good place to start. I myself like a firm shift but the transmissions don't last long if it's the opposite and slides into gear at a low mph.
