A transmission interlock assembly is described. A shift rail may include an interlock passage containing at least one interlock member. First and second gear engagement devices mounted to the shift rail may include, respectively, first and second interlock indents. The interlock member may extend into the first or the second interlock indent when, respectively, the first or the second gear engagement device is in neutral. With both gear engagement devices in neutral, as the first (or second) gear engagement device is moved to engage a gear, the interlock member may be urged out of the first (or second) indent and into the second (or first) indent, the interlock member thereby preventing the second (or first) gear engagement device from moving out of neutral. |

1. A shift interlock assembly for a transmission configured to shift between at least neutral, a first gear, and a second gear, the shift interlock assembly comprising: a shift rail with at least one interlock passage extending through the shift rail; a first gear engagement device mounted to the shift rail, the first gear engagement device being movable along the shift rail to engage the first gear, the first gear engagement device including a first interlock portion with a first indent, the first indent aligning with a first opening of the at least one interlock passage when the first gear engagement device is in neutral; a second gear engagement device mounted to the shift rail, the second gear engagement device being movable along the shift rail to engage the second gear, the second gear engagement device including a second interlock portion with a second indent, the second indent aligning with a second opening of the at least one interlock passage when the second gear engagement device is in neutral; a single-piece interlock pin having a length greater than the at least one interlock passage and less than a longest distance between the first and second indents, the interlock pin being contained, at least in part, within the at least one interlock passage, a first end of the interlock pin extending out of the first opening of the at least one interlock passage and into the first indent when the first gear engagement device is in neutral, and a second end of the at interlock pin extending out of the second opening of the at least one interlock passage and into the second indent when the second gear engagement device is in neutral; wherein, with both gear engagement devices in neutral, the first end of the interlock pin is spaced from the first indent, and the second end of the interlock pin is spaced from the second indent; wherein, with both gear engagement devices in neutral, as the first gear engagement device moves along the shift rail to engage the first gear, the first interlock portion urges the first end of the interlock pin out of the first indent, the second end of the interlock pin being thereby urged into the second indent to prevent the second gear engagement device from moving out of neutral; and wherein, with both gear engagement devices in neutral, as the second gear engagement device moves along the shift rail to engage the second gear, the second interlock portion urges the second end of the interlock pin out of the second indent, the first end of the interlock pin being thereby urged into the first indent to prevent the first gear engagement device from moving out of neutral. |
