Transmission control apparatus

A transmission control apparatus comprising:

• a housing;
• an inner shaft configured to be rotatable within a predetermined angular range with respect to the housing;
• a rotation lever configured to be rotatable along with the inner shaft to set a transmission position to one of Park (P), Reverse (R), Neutral (N), or Drive (D) positions;
• a solenoid disposed in the housing and configured to be interfered with the rotation of the rotation lever, wherein the solenoid includes a plunger that moves between a first side and a second side with respect to the solenoid;
• and
• a fixing means included in the rotation lever and configured to interfere with the solenoid,
• wherein the fixing means includes interfering members, which are formed to be engageable with the plunger when the plunger protrudes to one of the first side or the second side of the solenoid, and inclined members, which are inclined from the interfering members to press the plunger toward the other of the first side or the second side of the solenoid.
