2002 Liberty Transmission Trouble

[Lonewolf23234]

I have an 02 Liberty I was driving on the highway approximately 60 mph I heard and felt a few small clunks, this almost felt like the engine was miss firing, then all of a sudden the ****** dropped as if shifted into neutral. The weird thing and what I am not sure about is I have no gears at all, not even park, when I put it in park with the engine running I hear a grinding sound like it is to trying to catch, once the noise stops the ****** still acts as though it is neutral, have to use the park brake to prevent it from rolling. Anyone have any Ideas?? I assume replace the transmission??

How is the fluid level and quality? Has it been serviced recently? I'd drop the pan and have a look first, but doesn't sound good for that ******.

Fluid level s fine and fluid is clean, also even t was dirty or low, it would not effect park. I am thinking maybe the tcm but not sure that would effect park either.

Need to get it to a shop where they can scan it.

^^yup. No doubt there are some transmission codes being thrown there (not engine, won't thrown a DTC to turn on your check engine light).
Even if it were something simple like your shift linkage, it'd be stuck in drive since you were there when the clunks happened. Your fluid level may look clean, but that's because any debris would settle.. I'd be curious to see the inside of that transmission pan.

First step if you'd rather be positive about what it is, would be to take it to get it scanned. Even if it's work you'd rather do yourself, definitely would just get it scanned. If you truly are leaning towards tcm, you'll know from the codes.

scan ran clean no codes engine or ******

No codes and it won't shift? Linkage?

That's what I was thinking.. maybe the linkage shifted it into neutral before popping off. That would explain why you can't shift into any other gear. Only thing it wouldnt explain is the grinding noises you're describing

 

[Lonewolf23234]

linkage is connected if the internal bands broke it will not throw codes as the pressures are still holding just not mechanically capable of shifting I have seen this in older model ******
I have just not sen one not go into park, and I have limited experience with electronic controlled shifting.
