ahb08 Posted April 11, 2010 Share Posted April 11, 2010 Hello all, I have a 99 gs 300 with about 130k miles on it. A couple weeks back after driving around town for and hour or so I arrived back home, and attempted to put my car in PARK, well the shift gear would not go past NEUTRAL...it would shift from D > N and any other shifts below Drive. I kept trying to make the shifter go from N > R and it wouldn't budge...it was like it was locked....so i pull out the manual and it said in the event i cannot shift the selector even though the break pedal is depressed, i would have to use the SHIFT LOCK OVERRIDE BUTTON...so i looked up the instructions...and it showed were the shift lock override button was and now I have to depress this lock button EVERY time i need to switch from PARK to DRIVE and visa versa...there are no check engine or any other warning lights showing giving me hints to check something..I just went for an oil change yesterday and they say transmission fluid is actually good. Can someone please hlep me...Im scared to take it to a lexus shop were i ask for them to take a look at it i end not being able to get the car back without having to pay like 2k in repairs!! Does anyone know if this would be just a minor repair or is a whole new transmission needed???? Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted April 11, 2010 Share Posted April 11, 2010 Are your brake lights working? The problem cause could be as simple as a defective brake light switch on the brake pedal. If the switch fails, the shift lock override button has to be depressed to move the selector lever out of Park. I had one or two of these switches fail on an LS I drove for over 13 years.

1990LS400 Posted April 11, 2010 Share Posted April 11, 2010 If one or more of your brake lights is working, then it is less likely that the brake light switch on the brake pedal arm (under the dash on the driver's side) is the problem although the brake light switch can fail intermittently and still cause a shifter lockout problem. Replacing your brake light bulb at the back of your car "should not" help your shifter lockout problem -- at least it isn't supposed to.

Does anyone know if this would be just a minor repair or is a whole new transmission needed???? its a bad conection inside the shifter it self,, it needs to be cleand or replaced,, its deff not the lights, over time the iner parts of the shifter get worn out, nothing u can do about that,, i have the same thing, it comes and goes , but now it fine,, if u trying to save money get some1 who knows wat they r doing and have them open the colomn and clean where the contact is,,, ,,,,,,,,,,,,,,good luck Quote Link to comment Share on other sites More sharing options...
busterwoodham Posted June 21, 2010 Share Posted June 21, 2010 I have a 99 with 150k on it and my shifter locks up from time to time as well. I have noticed it happens mostly when it is cold outside and I have to use the shift over ride button when it does. Then its will go away for awhile. Thanks for the insight about the taking apart the assembly and cleaning the connections, i'll try that. Quote Link to comment Share on other sites More sharing options...
TBHudson Posted July 20, 2015 Share Posted July 20, 2015 Hello I seen your post and I know its old but I'm having the same issue with my car. Wanted to know if you got the issue fix, if so what was the diagnosis? Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted July 20, 2015 Share Posted July 20, 2015 Have you checked to see if your brake lights are working when you have to use the shift override button? (Throwing a towel on the back window can make easier to see if the high mounted stop light is lighting up.) If your brake lights are not working, the most likely cause is a defective brake light switch on the brake pedal lever - fairly inexpensive part.
