Excessive heat is the No. 1 enemy of AT's. At only 67000 miles, an auxillary transmission cooler is an excellent idea. Examine the 10,000 lb model.

My problems were many, but what ultimately got the traction control problem solved was a new ABS module and a reflash of the PCM. Turned out that the part # on the ABS that was provided to Ford for the replacement months ago was the wrong part #, albeit this part # came right from the module installed in the car. The only explanation that makes any sense is that the original ABS module was replaced with the wrong one. So replacing the wrong module with the wrong module again obviously doesn't solve anything. We proved it to the Ford service dept (they tried charging me another $700 for a different module), but got them to relent and take back the wrong one and replace with the correct one. Everything seems to be back on track, to use a bad pun...
Thanks to everyone for your input.

take some electrical contact cleaner and spray the mass airflow sensor. This will clean it, and might solve the driveability situation.
#54 of 99 transmission/engine noise

I have a 2003 Crown Vic Police Interceptor with 35000 miles on it. It was a light duty car for the Sheriff and his deputy, and never used for patrol. My problem is that it seems the engine and transmission roar louder than they should on acceleration. I have a 1995 CV and it is quiet and does not roar on acceleration. I know the 1995 car has lot's of insulation whereas the cop car has a vinyl mat and very little sound damping. Everything works correctly and the car runs great..no issues with tranny or motor..except they seem a little loud.
Also, the gas pedal is hard to push..it seems to have a lot of resistance, and gets very tiring on long drives without cruise control. It doesn't seem like it is binding, just hard to push. Can the accelerator cable be adjusted?
#55 of 99 Crown Vic transmission slipping?
Dec 02, 2007 (9:22 am)
i have a 2007 Crown Vic with 33K on it. I am having a problem whereby anytime the roads are wet, the powertrain seems to act out. It will usually happen when snow or ice are on the ground, but this makes no sense to me. First, the car will feel like a skip hits it. Then eventually, a lit wrench appears on the dashboard. The engine lihgt also illuminates and remains on. The cruise control also goes out. If i restart the car, everything is back to normal until the skip happens again.
I had this on my 2006 crown vic, and the dealership didn't know what the problem was because I could never get it there with the wrench lit. Anybody know what i'm talking about or have experiences with it?
#56 of 99 output speed sensor insufficient input
Dec 02, 2007 (2:50 pm)
2001 Grand Marquies 4.?L engine 32 K miles. The service engine light came on and the overdrive on/off light began to blink. Took it to autozone for a scan and it came up with the output speed sensor insufficient input code P0720. Is this possible it's just a bad sensor or can this be an input problem to the sensor? I can cycle the O/D button on the shifter a few times and the light will stop blinking on and off. Does anyone know where the sensor is located? Is this something I can change while changing the transmission fluid?

Hey just wanted to say that i have a 1991 crown vic and the tranny went out and i believe what your probably expering is either the od band is out or there may be a throttle valve which is a cable that goes from the top of the motor to the tranny and the top piece is mad out of teflon and it has gotton hot and burnt up. if those are not the case check the rear end my went out with the same shuddering and when it went out i was going down the insterstate and the axle and all flew out so be carefull. anyway i have work on tranny for the ford people for 19 years and there just saying they dont know couse they don't want to work or they want to wait for the right time so they can rip you off. just chek those couse after i fixed mine rear end and tranny i have never had trouble. i have owned 3 crown vics and all have had tranny trouble. good luck

Ok I have a 94 grand marquis and the trans just started acting up on me yesterday. It wouldn't shift into park and the gears fear loose when I shift to them. I found a bolt in the driverside floor board and it have no idea what it goes to. Please give me some kind of feedback on this problem.

1. Not shifting into Park may require a minor linkage adjustment.
2. Not knowing how many miles since you had a fluid change, perhaps that is due. Remember to also drain the torque converter and install a new filter in the transmission.
3. The bolt found on the floor board may be related to the need for linkage adjustment, but I doubt it. Your Mercury dealer parts manager would know by showing it to him.
