The linkage has slipped and when i go to wash car I can't find neutral.

Could you please comment below with more information about the vehicle this is happening to? Make, Model, engine size, Year it was made, Manual or automatic gearbox.
On a manual transmission the three most common reasons are...
Old or low transmission fluid.
Badly adjusted shift linkages.
Worn Syncro-mesh rings.

bent linkage - or failed motor mount. The engine at idle has little torque so the linkage isn't really where it needs to be - once revs are increased - torque increases and the twisting of the engine on the remaining mounts is enough to keep the linkage in place. Either way, probably not a very expensive fix.

Hi Chris:
If you can get at the linkage and pull it back into neutral it should function for a while.
I found that on older vehicles with manual transmissions the "gates" in the linkage shift assembly got worn so that when a fast shift was attempted, the shift knob (lever) would move, but the pin connector would slip out.
Be safe. Work off a hoist or have the vehicle on jack stands so that you can safely get at the transmission where the linkage levers are attached.

clogged filter low fluid or bad ******

if trans not slipping and shift o.k true out its shift range
i would look at adjustiing the selector swich if electric
or lever control if linkaged if electric a new selector swtch may be required
if linkaged parts in linkaged may start to wear (bushings etc)
also look at engine and motor mounts if system is linkaged

under hood on top of trans, it has slipped the linkage reajust linkage. W/EMERGECY BRAKE ON

It sounds like the linkage in the transmission has slipped. Check the linkage adjustment from the gear shift to the transmission. It sounds like it has slipped into neutral, and automative transmissions will not start in neutral.
Try moving the gear shift back and forth and have a friend see if the linkage, viewable from under the hood (though you may have to remove the air box first), is moving as well. If it is, disconnect the cable off the link and manually push the arm into park. Try to start the car. If your car starts, then this is definitely the problem. Go to your local transmission dealership for information on repair.

flywheel needs replaced; or linkage is loose; Could be low on fluid

Your linkage could be loose; low on transmission fluid; or you need a new flywheel
