Hi,

Just wondering if the replacing the Shift Lock Solenoid will fix the clicking sound when the car is in Park and brake pedal is pressed? The click was a bitter quieter back then, but recently it has become louder. My mechanic mentioned that is the part that is needed. I just want to double check with you guys. Thanks.

Maybe some grease might help?

Hi,

Thanks! I'm a newbie. So do you mean greasing the solenoid? PLMK. Thanks.

I dont think you need to grease the solenoid, clinking sound means that the solenoid is working repeatedly (on and off continuously) because of bad contact of the shifter switch. The shifter switch senses P position and send a signal to solenoid to release shifter lock when you depress brake pedal

the one to replace/ clean should be the shift lock switch, not the solenoid. I am having similar issue with my shiftlock control but cant find the replacement part. I now need to use Shift lock override button instead

that little button down by the shifter ( I have a '91 ls400) is that supposed to be able to be pushed mine seems to be broken, or can you tell me what is that little button's function at least?

Hi,

So is it possible to get that part? PLMK.

@Nawls400: if you cant move shifter out of P while stepping on brake, that little button (named shift lock override), depressed and held, will help you to by pass the electronic locking mechanism

@en11871: i cant find it till now, i am using shiftlock override button every time the locking mechanism fails. its kind of on and off due to bad switch contact i believe

ok cool, that clears it up...thanks man!

qha,

Thanks for your replies. You mentioned above that "the clicking sound means that the solenoid is working repeatedly", but the clicking noise/sound is just once everytime I step on the brake pedal in Park. Just wondering if the one clicking sound is different from your "working repeatedly" the same. So the new solenoid help? So it is called "Shift Lock Switch"? How much is that piece and can I just ask Lexus for the part under that name? PLMK. Many thanks.

from my experience, if you still hear clicking sound when stepping on brake pedal, most likely the solenoid still works as it is the only thing that produces sound in shift lock mechanism

if you have access to a Lexus dealer (lucky you) just explain the symptom to them and do NOT say anything about shiftlock control switch or solenoid as these things may cause missleading and cost you more as a result

as I mentioned below, I cant find replacement part online so I dun know how much it would cost you

To me, your "one click" may mean that you solenoid is still working fine, your "shift lock control switch" is still fine. problem may be at the linkage between solenoid and the latch that locks the shifter

if you want to learn more about how the shift lock system works, please go to http://www.autoshop101.com/ and click on "Shift Interlock System". They explain very clear that you may want to fix it yourself

hope this helps
