    Ok, so at first all it was doing was slipping in fourth after 45mph. Then it only had second gear and I decided to start overhauling the drivetrain. I have replaced both control boxes under the dash, changed the fluid and filter, checked the shift linkages and made sure the transmission was fully engaging the gears. After I put it all back together it only had first. Then it had first and second, and then even third for a short period of time. Now it's back to just 2nd and it makes a slight grinding noise in reverse. I am looking at a master overhaul kit, shift kit, and torque converter from b&m. Anyone have any suggestions?? and how do I adjust the kick-down cable??
  • As i was approaching a sharp left turn, i released the gas and car suddenly accelerated turning close to 4000 rpm. Applied the brake and it would not slow down the car and i went straight thru [ small country road] Quickly put transmission in neutral and engine slowed to normal. Went down the about 2 blocks and turned left into a driveway and this senerio repeated it self. Drove fine after that. Can anyone help me with problem. Thank you in advance,newbie Donavan2

    Are there computer challenges to solve in this modification?
  • Hello, I am looking to buy a 2000-2005 Crown Vic RCMP car. I have heard that they have a strickt maintenance schedule which includes engine and transmission changes. Is there a preffered KM range where one should have a new engine and/or transmission, or is it basically the lower the KM the better? Are these good reliable cars and is there anything specific that I should looking for on these cars? I have owned a 1993 Caprice RCMP car, and that thing was incredible. I sold it around 400,000 KMS for something a little cheaper on gas and even at those KMS it still ran great. I am hoping that these police cars are as durable and reliable. Thanks for any information and help.

    Every police car has been treated differently & run in a wide variety of ways. When you choose a low KM car, you might be getting one with an engine with lots of hours on it due to long periods of idling. To choose the best, drive them all, but if you do purchase one, change all the fluids including the pinion housing & replace with Synthetics. If you are good at the Casinos, try your luck in Regina.

    I would like the default startup condition to be overdrive off and then change that by pressing the OD button. I would always like the startup to be overdrive off just the opposite of the factory setting. Is there a way to do that?

    When the tranny shifts from 1st to 2nd, it jumps then goes into gear. Do I need a new trans shift sensor or etc solenoid or tcc lock up solenoid? :confuse:

    What occurs when you shift manually from 1st to 2nd to 3rd?
  • I hae a 1998 Mercury Grand Marquis LS w 168,000 miles. Car usually runs great, avg. 20mpg. Bought car about year and a half ago. Has had occasional light shudder when lightly applying gas between 35/40 mph. Other day did shudder every time a tried to keep steady speed of 55 and higher w light acceleration . Very scary , no shudder with heavy acceleration. Sucks gas when this happens,

    Change the transmission fluid & replace with Mercon V. Don't use the forcefull system, but drop the pan and replace the filter. The shudder will not be. It worked for me. :)
