This is old tech and rarely seen unless you drive a refuse truck which most of these shifters were used on. I believe Allison went to a keypad style setup in '94? It's all new to me as well. The only real reason T.H. Anderson services these is due to the fact they are primarily used on oil field pump transmissions. If not for that, I would have to learn to dissect and make parts for this.
