1995 crown vic gear problems/gear shift wont lock

Check the trans fluid with in neutral. If low, put some in. Would not be electrically actuated so fuses have nothing to do with your situation.

check the linkages from the gear box to your gear stick may be loose.

I have a 92 Crown Vic first and second works fine reverse works fine when it shifts in the third gear it goes to slipping and overdraft can you help me fix this problem thank you

Check the solenoid mechanism on the shifter to check that it is disengaging the shift lock mechanism when the brake switch and ignition are on.

check pressures for drive gears if not in range then possable bad clutches in the ****** if you have a scan tool scan for shift coads and tern your shift sylinoids on and off to see if you have engagement if not rebuild or replace

Unless you are low on fluid, I suspect you are in need of a rebuild. I have had similar problems before. Any shop will tell you to try a fluid and filter change. It has never brought one of mine back. I would suggest adding fluid to the top of the 'add fluid' area of the dipstick and no more. It can foam if it is to full, causing similar problems as being to low. I would add that if you have to replace the transmission - you need to consider that the car may not be worth the cost.
Good Luck.

Have he transmission drained and the screens cleaned

If check engine light is on ,remove battery cable, you have an electrical problem, maybe fuse?

if the shifter is loose and sloppy feeling then the shift cable bracket has come loose under the dash at the steering wheel. remove the lower panel under the steering wheel so you can see under the dash then get flash light and look while jiggling the shifter. you should be able to see the cable and bracket. if the bracket is loose then tighten the bolts. note this bracket is at the steering colum.

Check transmission fluid levels,,replace lost fluid as needed,,,if this does not work,,take the car to a mechanic,,,sorry to say,,this kind of problem almost alway's requires a transmission mechanic to repair.
