99 disco 2 stuck in park. It was hard putting it into park that it stuck there. I can manually release it and start it in neutral. Basically I don't think it knows it's in neutral. Is my xyz switch cooked?

 

The first thing to check for a DII stuck in Park is the brake light switch.

This topic has been covered literally dozens of times in this forum.

I don't understand why everyone wants to leap to the XYZ switch being the problem.

Start with the inexpensive solution, and if that doesn't work move up the scale toward more expensive solutions. The XYZ switch is a more expensive solution.

Or better yet, diagnose, diagnose, diagnose before leaving to an expensive part and expensive repair. Test the brake light switch, for example.

In the meantime, you can get your fingers under the plastic bezel surrounding the shifter, lift it up, and manually move the solenoid to release the shifter from Park.

Again, there are dozens of threads about this on this forum.

 

well I originally posted this in the wrong spot so I reposted here. Thanks for the criticism that always helps. While working on my truck I didn't take time to write a book here. I read "dozens" of threads and the indication was that if my brake lights are working my switch is fine.

​​​​​​brake lights work.
all indicator lights on the console light up except park
I can start it just fine in neutral. But not in park
When I pushed the shifter forward into park it bound up for a second. Now everything works fine except I don't think it knows it's in park

I didn't jump to the xyz. I diagnosed as best I could from other threads, and came to that summation and would like feed back from someone with experience

 

I ran into the situation where sometimes I would not be able to start because it wasn't detecting that I was in Park. If I shoved the shift lever forwards it would sometimes register. I cured that by removing and cleaning the XYZ, for zero cost.
If the brake lights work correctly, then your brake switch probably isn't the problem. However, we did not have that information.

 

I understand. People always assume you're stupid if you don't tell them everything you already read or tried. It's easier to ask questions to assist diagnosis than it is to criticize.I stated the vehicle doesn't know it's in park. A brake switch won't prevent it from knowing it's in park. I was working on it when is wrote my initial question. I should have been clearer.

So based on your experience. If it doesn't know it's in park, the xyz has to be the culprit?

 

@suzukisam If I follow correctly your Disco will start in Neutral but not in Park it is more likely the lock out plunger I would think

You need to start simpler :

• Pop up the transmission bezel, be gentle it just lifts straight up. You should be able to do this with the gear **** still in place
• Check that the gear selector is all the way forward there is a lockup pin that allows you to start
• Put it in neutral you will see the pin location should look the same in park

 

I was assuming by saying "I can manually release it" that the OP was meaning that the bezel was being lifted up and the pin pressed so that the vehicle could shift into neutral, at which point it could be started. I don't think it's accurate that the lock pin is in the same position in neutral as it is in park. The lock pin prevents accidental shifting into/out of park.
Not sure what could be the cause of it being difficult to shift into park, but perhaps that could be related to the lock pin. I don't think the lock pin forms part of the starting circuit though, so it would be unrelated to the no-start condition anyway.

 

exactly. This is correct
It is fully forward. And if it were the plunger it would start. the plunger is only activated by the brake switch while in park. So if it doesn't know it's in park, the brake switch and the plunger are on a dead circuit. The circuit is heated when the park circuit is activated.

I'm an electrical diagnostic tech.. Guess I should throw that out..

 

you are correct but I've verified all this prior to posting

 

Have you gotten under the truck and looked at the cable mechanism? If the circlip slips You will not be able to move the lever far enough forward to get to "home" in park. Just a thought...
