Nadie responde a mi consulta  al parecer algunos de ustedes no en pasado por lo mismo, tengo serias dudas de mi vehículo Hyundai Excel año 93 caja electrónica, funciona los cambios como a tirones y no funciona el retroceso, pienso que puedan ser los solenoides pero necesito  estar seguro son demasiado caros. Al calentarse la caja (el aceite) pierdo toda tracción del vehículo. Revisado  el aceite, bomba, ectr.

NEUTRAL SAFETY (INHIBITOR) SWITCH


The inhibitor switch is located on top of the transaxle case. This switch has the manual control lever attached to it and the selector cable attached to the lever. It is also a neutral safety switch that will prevent the vehicle from starting in any gear except P or N. The inhibitor switch also completes the reverse light circuit when backing up.



1.Disconnect the negative battery cable.
2.Place the selector lever in the N position. Loosen the manual control lever flange nut to free up the cable and the lever.
3.Place the manual control lever in the N position.
4.Turn the inhibitor switch body until the 0.47 in. (12mm) wide end of the manual control lever aligns with the switch body flange. Tighten the mounting bolts to 7-9 ft. lbs. (10-12 Nm) torque.


.When setting up the switch body, be careful not to drop the O-ring from the switch body. Tighten the switch body carefully.
