i recently got a 02 tl s and everthing was fine for about 5 hours. when i got it i noticed the 1 (D1) light stayed on at all times but i figured i would figure it out. after i filled up the tank the day i got it, it wouldnt shift out of park so i forced it with the override thing. for the next week it would sometimes shift out of park when it wanted to but if i forced it out of park the tranny would shift at high rpms, when it decides to shift out of park, it shifts fine, super smooth, so lately its been parked cause i dont want to mess up the tranny.

i switched out the shifter assembly so the 1 light is now gone, but it still wont shift out of park.

the brake lights light up when i press them, so im assuming the brake light switch is fine.

previous owner spilled coffee on the shifter so im assuming it was shorted but the harness has since been cleaned as well as a new but used shifter assembly.

i am so lost right now, the car will nt shift out of park at all, no check engine lights at the moment.

any help woulp be appreciated, im willing to try everthing.

 

does it work fine when you insert a key into the shifter unlock slot next to the shifter? if so, then I would inspect that whole shifter lock circuit. the switch you mentioned you checked, the solenoid underneath the shifter and the power supply to that shifter as well as the trigger. the service manual may be needed to check for any fuses associated with that circuit.

 

You need to feel click at transmission sifter handle when you press brake.

 

Had the problem for a while. Started the car in nuetral and drove around. Usualy its an issue with shift linkage (per other threads) my problem went away after doing all the brakes. But it may not have actually fixed it as it was an intermittent problem.
