#37 of 87 Re: What to do about stiff 1999 Marquis ride? [mlowner] by turbo301 Oct 16, 2006 (2:40 pm)
Replying to: mlowner (Oct 11, 2006 2:49 pm) While not necessarily a defence, what you're probably experiencing is the frame transmitting vibrations throughout the car. I love body on frame, but that is one of its drawbacks. To say that these cars ride harshly (or handle like sportscars - still an astonishing thing to say!) is certainly an over-reaction, though. Pre-2003 Panthers are perhaps the softest, most wallowing machines made in the last decade! My 2004 Crown Victoria runs 37 psi in the tires, and the ride is still very nice: you feel the bumps, no doubt, but it's still softer than my '85 Grand Marquis with the handling package was.   While I'm here, am I the only one who can't help but laugh at the notion of replacing springs in these cars with SOFTER ones? The typical thing to do when modifying a car to get it lower, make it stiffer, etc. and yet there's so much talk of going the OTHER direction on Panthers. It's just kinda funny ^_^.   And, Panthers are an excellent start for a performance car. Lots can be done with the 4.6L (or stuff a supercharged 5.4L under the hood?), and just think of the wild sleeper you could make!
#38 of 87 mysterious chugging by whitebread64 Nov 24, 2006 (9:08 pm)
I recently purchased an '01 Grand Marquis LS with the 4.6 in it. It had 67,00 miles on it. I have noticed lately that anywhere from 40 to 60 mph it sometimes "chugs", or jolts when I slowly accelerate. My uneducated guesses have led me to believe that it is either the transmission or something to do with the electronic ignition, but in reality I have no clue. Any suggestions so that I can try to avoid getting raped by unscrupulous mechanics would be greatly appreciated.

Replying to: whitebread64 (Nov 24, 2006 9:08 pm) Having experienced the "shudder" - it is recommended you change the oil in the transmission and torque converter. You should then be good for another 40,000.

Replying to: whitebread64 (Nov 24, 2006 9:08 pm) 14 quarts of Mercron V transmission fluid - make sure they drain or pump out the fluid in the torque converter. I think the 2001's still have a drain plug in the torque converter. If you don't have a drain plug, the mechanic might have to disconnect a line at the transmission cooler and let it pump out. My opinion is to not "flush" the transmission, but drain the fluid, drop the pan and check for debris, clean the magnet, and change the transmission filter.   Labor might be a little higher, but if you use high quality fluid (like Amsoil), you should be good for another 100,000 miles.   This could be done by an average shadetree mechanic, but trying to remove 14 bolts from the transmission pan while on my back is no longer something I'd like to try.

Replying to: whitebread64 (Nov 24, 2006 9:08 pm) Have you had your spark plugs and especially your spark plug leads checked or changed? A spark plug lead which breaks down can cause the engine to miss and the car to chug, jerk, or jolt. Sometimes this engine miss from a faulty spark plug lead happens under light acceleration rather heavy acceleration. Two or more bad spark plug leads can cause the car to really jerk, chuck, etc. Fouled spark plugs can cause the car to jerk, chug, etc.

Replying to: brucelinc (Jun 09, 2006 4:56 am) If you have the single exhaust you do not have the handling package   Thats funny, I have single exhaust and the handling package, so that statement would be false, just wanted to correct you on that.
#43 of 87 '91 CV LTD wagon tranni(?) problem-lady needs help by teachinjose Aug 11, 2007 (1:44 am)
Hi everyone,   I inherited my father's '91 CV wagon, LTD, w the 5.0 and it's been great, but the tranni has been whirring at about 40 mph for the last 2 yrs. or so. To compensate, I start in overdrive, 0 to 40, hear the whir, switch to drive, then accelerate to 60, when I can get back into OD again to save gas. If I don't do this, the trani makes this slipping sound and the car hesitates. I switch the gears cuz I don't want to wreck the transmission. ( I had an '85 Buick Cent. T that took 6 rebuilt tranis,(GM 440's), but got 185K miles out of it.) Any ideas on how to fix this? Thanks. Teacher in San Jose
#44 of 87 tranny slipping? by hyphy Aug 30, 2007 (6:05 pm)
yes i have a 97 vic. and sometimes when i excelerate the engine revs for a few second then it will shift. what could the problem be and how and how much does it cost to fix Replies to this message: euphonium (Aug 31, 2007 10:13 am) jsylvester (Sep 01, 2007 6:20 am) captain131 (Sep 14, 2007 2:34 pm) bestracer500 (Jan 26, 2008 7:19 pm) teachinjose (Sep 15, 2007 7:31 pm)

Replying to: hyphy (Aug 30, 2007 6:05 pm) If you have over 40,000 or it has been 40,000 since, change the transmission oil including the turbine. If you plan to keep the car change to a semi synthetique, it's costly, but lasts longer and performs better. Mercon V is the one.

Replying to: hyphy (Aug 30, 2007 6:05 pm) It's hard to say - usually the sign that the transmission fluid is old is you will start to get "stuttering" when the transmission tries to shift into 4th gear. As mentioned above, it is the torque converter that gives you warning of that issue.   The poster above is correct in regards to the fluid to use - Mercron V is backwards compatible with all Grand Marquis back to 1992.   This is just my personal preference, but when I change the fluid, I drop the pan and change the filter as well - in my mind power flushing just forces all the dirt in the filter back into the transmission. That will also allow your mechanic to see how much trash is attached to the magnet in the pan, and whether there is something more serious to fix.
