My 90 accord is having issues when cold with the part I described in the subject line. The end result is on a cold day, if I try to shut the car off before it warms up a good amount it will not let the key unlock the ignition.

I will put the car in park but the tranny gear indicator on the dash never fully goes in park until i hear an audiable "click" from around the shifter area.

When that part is acting up when cold, I can hear that same click every time I press the brake when it's in park.

It seems pretty obvious at this point that auto tranny locking mechinism is very sticky and unreliable when cold.

 

Here's a good read http://techauto.awardspace.com/ignit...tch.html#stuck

(35700-SM4-A91) SWITCH ASSY., AUTOMATIC TRANSAXLE GEAR POSITION and the solenoid is called (39550-SM4-A83) SOLENOID ASSY., AT (SHINDENGEN).
It could be that the (30158-700-010) E-CLIP (3MM) may have fallen off and the (54024-SD4-A40) PIN, SOLENOID may be cockeyed not allowing the solenoid to fully engage the switch.

 

Thank you for the reply. One last thing, how do I translate the parts #'s you gave me to the schematic part #'s? Thanks again
